NIDEC’s Three Essential Attitudes: The Operating System Behind Purpose-Driven Manufacturing

Posted on by Samantha Hambleton

In an era of rapid change, tighter targets, and rising expectations for speed and quality, the companies that endure pair a clear purpose with decisive action. At NIDEC, our philosophy is straightforward and ambitious: design ever more efficient products and improve people’s lives.

Our Three Essential Attitudes, or the “NIDEC Way”—Passion, Enthusiasm, Tenacity; Working hard and smart; and Do it now, do it without hesitation, do it until completed—are more than values on a wall. They guide our teams, our projects, and our partnerships every day.

Below is how these attitudes take shape across our operations, and why they matter for our customers’ competitiveness and for a better industrial future.

Passion, Enthusiasm, Tenacity: Fuel for Innovation

Complex manufacturing challenges rarely resolve in a single sprint. They demand cross-functional collaboration, patience, and the will to iterate. Passion drives ambitious goals. Enthusiasm sustains energy through setbacks. Tenacity ensures we finish the job.

How this shows up at NIDEC:

  • Engineering depth with customer empathy: We don’t just tune specs. We understand throughput constraints, floor layouts, workforce skills, and maintenance cycles.
  • Iteration without fatigue: Whether refining hobbing parameters for micro-geometry accuracy or stabilizing thermal behavior on a machining center, we pursue precision with persistence.
  • Lifecycle commitment: From installation to optimization, we support the full lifecycle, not just the handoff.

Working Hard and Smart: Effort Meets Evidence

Advantage comes from pairing effort with data, process discipline, and the right tooling. That’s how we reduce variability and increase productivity without compromising quality.

How this shows up in our solutions:

  • Application engineering and prototyping: At the NMTA Gear Technology Center, we use our latest gear cutting machines in real-world trial cuts and prototyping to dial in optimal processes before they reach your production floor.
  • Gear inspection and data feedback: State-of-the-art gear inspection equipment verifies quality and feeds measurement data back into process adjustments, tightening tolerances and improving repeatability.
  • Rebuilding, reconditioning, and control retrofits: By rebuilding systems and modernizing older equipment, we extend the life of proven NIDEC platforms while elevating accuracy, reliability, and ease of use.
  • Lifecycle optimization: Through installation, training, maintenance, and ongoing process support, we keep machines running at peak performance and continuously identify opportunities for improvements in cycle time, quality, and uptime.

Outcome: Shorter cycle times, fewer rejects, lower operating costs, and more stable production windows, especially in high-precision environments.

Do It Now; Do It Without Hesitation; Do It Until Completed: A Bias for Action

Delayed decisions defer value. We move decisively, aligning stakeholders, clarifying requirements, and executing with urgency. That discipline accelerates learning and delivery.

How we put action first:

  • Rapid discovery: We define the problem precisely, from target tolerances to surface finish, and get aligned quickly.
  • Prototyping and validation: We run trials, gather data, and iterate to de-risk production.
  • Finish the job: Implementation is the start, not the end. We stay engaged through ramp-up, operator training, and process stabilization until performance holds.

Outcome: Faster time to value, fewer surprises during launch, and sustained performance in real production, not just in a demo.

Why This Matters Now

Manufacturers are navigating:

  • Labor constraints and the need for intuitive, reliable machines
  • Pressure to compress lead times while increasing customization
  • Tighter tolerances for gears and precision components

NIDEC’s Three Essential Attitudes speak directly to these pressures. Passion, enthusiasm, and tenacity keep teams moving through complexity. Working hard and smart grounds improvements in data and repeatability. A bias for action cuts time-to-outcome and keeps initiatives from stalling.

The result is better manufacturing systems: efficient, resilient, and ready for what’s next.

A Better Future, Built One Completed Task at a Time

NIDEC’s corporate philosophy guides our daily decisions. The Three Essential Attitudes turn that philosophy into action on the factory floor and in the boardroom. When teams embrace them, projects move faster, machines perform better, and the long-term impact compounds.

Gear History at New Year’s: The Mechanics Behind the Date Jump

Posted on by Samantha Hambleton

On New Year’s Day, it’s easy to focus on the countdown to midnight. But if you wear a mechanical watch, there’s another transition happening in the background: a small gear train advances the date disc by one exact step.

That seemingly simple jump is the product of more than a century of incremental work on calendar displays, culminating in the mid-20th century with robust date and day-date mechanisms that are still the template today.

How Mechanical Date and Day-Date Mechanisms Work

Mechanically, most traditional date and day-date systems share the same basic architecture.

The hour wheel drives an intermediate wheel. That intermediate wheel drives:

  • A star or date wheel with 31 teeth (date).
  • A star wheel with 7 teeth (day of the week) in day-date watches.

Each of these star wheels advances by one tooth every 24 hours.

The intermediate wheel is important: without it, the calendar would advance twice per day. With it, the system steps once per 24-hour cycle and typically changes around midnight.

To hold each indication precisely in place, the system adds:

  • A jumper spring that engages between teeth on the date (and day) wheel.
  • A shaped cam or finger that gradually loads the jumper and then lets in snap into the next tooth, depending on whether the change is standard, semi-instantaneous, or instantaneous.

From a gear-engineering perspective, that means very small modules and teeth must withstand:

  • Cyclic loading from the daily change.
  • Long-term boundary lubrication.

Backlash and tooth form must be controlled so the indication:

  • Lands on center.
  • Resists vibration or partial movement between jumps.

It’s essentially a micro indexing drive synchronized to a 24-hour input.

Short Months and Manual Corrections

Standard date and day‑date mechanisms are built on a simple assumption: every month has 31 days. In a non‑perpetual system, this means the date must be corrected five times each year, whenever the actual month length falls short of 31 days 

That simplification keeps the movement compact and relatively straightforward, but it pushes some of the complexity onto the user. To deal with real‑world calendars, watchmakers provide ways to “force” the date mechanism to advance. In modern quick‑set systems, the crown (or, on some watches, corrector pushers) lets the wearer rapidly click the date forward, and in some designs also change the day or month, one indexed tooth at a time. Earlier non‑quick‑set watches are less forgiving: the only way to update the date is to repeatedly rotate the hands past midnight, cycling the 24‑hour mechanism over and over.

In both approaches, the calendar train has to tolerate behavior that goes far beyond the gentle, once‑per‑day change it was nominally designed for. Rapid corrections impose many small, user‑driven shock loads in quick succession. On top of that, there’s the risk of overlap between human inputs and the watch’s own automatic changeover. If the wearer tries to adjust the date too close to midnight, while the change mechanism is partially engaged, there’s potential for damage. 

For gear designers, this will feel familiar. The mechanism is sized and optimized for the ideal operating case: one clean step per 24 hours. But its durability and real‑world reliability are defined just as much by edge conditions: irregular month lengths, impatient users advancing the date as fast as they can, and ill‑timed inputs right in the middle of an automatic change.

What This Means for Modern Gear and Mechanism Design

For engineers working on other gear-driven systems such as indexing tables, rotary actuators, and small step-feed mechanisms, there are a few direct takeaways:

  • Continuous rotation to discrete steps: Calendar mechanisms show a clean way to derive discrete, repeatable steps from a continuous drive, using gear ratios and spring-based jumpers rather than electronics.
  • Load and tolerance discipline at small scale: Because the teeth are tiny and the loads are light but persistent, tooth geometry, backlash, surface finish, and material choice become critical over long life.
  • Designing for human interaction: Manuals from brands and historical overviews emphasize care when changing dates, especially around midnight. The mechanisms are robust but not invincible, a reminder that real users will always push designs outside nominal states.

A New Year’s Perspective

Each New Year’s Day, when the date rolls over from 31 to 1, the same fundamental mechanism that advances the date every night does its job once more: a small, carefully cut set of wheels moves exactly one tooth.

2025 Year in Review: Advancing Manufacturing with NIDEC

Posted on by Samantha Hambleton

As 2025 comes to a close, NIDEC MACHINE TOOL AMERICA is reflecting on a year that combined strong technical progress with deeper collaboration across our customers, partners, and global NIDEC teams.

The Origin of Hobbing: From Craft to Scalable Precision

Posted on by Samantha Hambleton

Before hobbing, cutting precise gear teeth was closer to an art than a repeatable process. Output depended on time, cost, and the operator’s touch. That began to change as innovators pursued a different idea: generate the tooth form through controlled motion rather than copy it one space at a time.

Three milestones set the trajectory:

  • In 1835, Joseph Whitworth patented hobbing for spiral gears.
  • In 1856, Christian Schiele patented an early hobbing machine, helping establish the generating approach that would define modern practice.
  • In 1897, Robert Hermann Pfauter patented hobbing for spur and helical gears, cementing the method as the backbone of production gear cutting.

Why hobbing changed everything

At its core, hobbing synchronizes a helical cutter with the rotating blank so the correct tooth geometry emerges from their relative motion. That shift delivered durable advantages:

  • Accurate involute profiles at speed, improving mesh quality and efficiency.
  • Much higher throughput at lower cost per part, enabling true volume production.

How it reshaped manufacturing

Hobbing didn’t remove the need for expertise; it codified it. Predictable kinematics lowered the skill barrier and made high quality teachable and repeatable. That predictability supported the rise of transmissions, differentials, timing drives, and industrial gearboxes across sectors, from automotive and energy to automation and robotics. Over time, hobbing helped drive standardization and rigorous inspection practices, while integrating naturally with heat treatment and finishing.

A line that leads to the future

Expectations keep rising: tighter tolerances, faster iteration, and greater sustainability. The principle Whitworth and his successors helped establish still underpins modern manufacturing, but today’s tools must scale precision and agility together.

This is where NIDEC’s hobbing machines fit. NIDEC machines are built around what matters most now:

  • Repeatable quality across programs and volumes.
  • Agile production that adapts to new designs and shifting demand.
  • Cohesive workflows so teams can move from prototype to production with confidence.

Hobbing turned gear cutting into a scalable science. The next chapter belongs to manufacturers who keep elevating the process. NIDEC machines are built for that future, helping engineers deliver the next generation of drivetrains, robotics, and industrial systems.

Gear History: From Shipwreck to Shop Floor–What the Antikythera Mechanism Teaches Modern Gear Engineers

Posted on by Samantha Hambleton

Around 2,100 years ago, long before CNC and CMMs, Greek craftsmen built a compact, hand-cranked computer of bronze gears: the Antikythera Mechanism. Recovered from a Mediterranean shipwreck in 1901, it has been reconstructed from fragments and inscriptions; recent work proposes a coherent design that models the motions of the Sun, Moon, and planets according to ancient Greek astronomical theory. Beyond its historical significance, it offers practical lessons for anyone designing drivetrains, automation platforms, or precision instrumentation today.

A Compact Astronomical Computer

The Antikythera Mechanism is a densely layered assembly of bronze gears housed in a wooden case with engraved dials. Turn a hand crank and pointers sweep across scales that predict eclipses, track lunar phases, and represent planetary positions. Its gear trains encode astronomical periods such as the Metonic cycle (about 19 years) and the Saros cycle (about 18 years and 11 days), combining them into legible displays.

Engineering Ideas, 2,100 Years Early

  1. Differential thinking, ancient style
    • The challenge: The Moon’s apparent velocity varies because of its orbital anomaly.
    • The solution: Epicyclic trains with a pin-and-slot mechanism produce a modulated output from a uniform input—an analog “differential” that synthesizes non-uniform motion.
    • Today’s echo: The same logic underpins differentials, harmonic drives, and cam-like modulation in robotics and precision stages, where uniform motor input is transformed into time-varying motion at the load.

  1. Ratios as models, not just reductions
    • Tooth counts were not arbitrary; they encoded astronomical ratios. Preserving those integer relationships across multiple stages maintained phase fidelity.
    • Today’s echo: Start with a high-fidelity model to define ratio architecture. Whether mapping encoder counts to motion profiles or matching gear stages to spectral requirements, ratio selection should be driven by physics and output specifications.

How Well Did It Work?

Reconstruction studies show a kinematically consistent mechanism that aligns with surviving fragments and inscriptions and can demonstrate and predict astronomical cycles.

Why It Still Inspires

The Antikythera Mechanism compresses theory, design, fabrication, and communication into a unified product. It foreshadows differentials, compound reductions, and cam-like motion synthesis in today’s transmissions, robots, and metrology instruments. For modern engineers, it’s a reminder that lasting engineering couples precise internal models with trustworthy external displays.

If you build drivetrains, automation, or instrumentation, the lesson is timeless: let high-fidelity models drive your gear-ratio architecture, and let clear displays earn operator trust.
