Bring the problem. We will find the path.

Start with a part number, a drawing, a measured load, or a failure. We will identify the next useful engineering step.

What gets measured.

A datasheet is a summary of somebody else's test. The useful work starts where the summary stops: at the operating point your mechanism actually sits at, on the duty cycle it actually runs.

Motor MM-C1636-060B, the winding inside configuration MM-C1636-P00203-060B. Drawn from the four published points: no-load speed, no-load current, stall torque and stall current. The straight lines are the linear model, not a measured curve. A real machine departs from them near stall and as the winding heats, which is exactly why a screening result is not a qualification.

The four questions a screening answers

  1. Where does it sit on the curve?

    The operating point, not the rated point. Speed, current and dissipation at your load, with the margin to stall stated as a number.

  2. Does the geartrain survive the duty?

    Peak and RMS output torque against the gearhead limit, stage count against backlash, and the start transient that a continuous rating never covers.

  3. What is unknown?

    Every value we hand back carries its basis: published, calculated, typical, or a limit. What we have not measured is named, not smoothed over.

  4. What single test closes the gap?

    One test, named, with the sample it needs. A comparison table is a screening. Test evidence is what qualifies a part.

Run an operating point yourself

What comes back.

A screening packet, not a quotation. It is written so a mechanical engineer, a controls engineer and a buyer can each find the part they need in it.

  1. 01The candidate configurationA Micro Motion public SKU with a complete reviewed record behind it.
  2. 02Dimensional comparisonEnvelope, shaft, mounting and total length against the part you sent.
  3. 03Electrical comparisonVoltage, no-load and rated current, stall current, and what the driver has to survive.
  4. 04Speed and torque comparisonAt your operating point, with the margin to the gearhead limit stated.
  5. 05Known differences and assumptionsWritten out. Anything we assumed is listed where you can argue with it.
  6. 06Sample or prototype statusWhat can be built now, what needs configuration, and what needs tooling.
  7. 07A test and qualification planThe evidence that would turn a screening into a design-in.

We know what makes a gearmotor hold up in production.

Micro Motion is led by an American sub-fractional horsepower motor manufacturer who learned the production system by running it: stamping laminations, hobbing gears, machining pinions, winding coils, molding magnetic material, pressing pins, welding housings, building the tooling, assembling gear trains, testing, and finding out why a line stopped. That is why the conversation can go past the datasheet and into the process that decided the number on it.
