Micro
Motion Talk to an engineer

Cross-reference the motor already in your machine.

A printed number, a nameplate photograph, a drawing, a datasheet, or the unit in a box. One legible identifier starts a project.

Is this the problem I have?
The mechanism stays. An obsolete, unreliable, unavailable, or over-cost motor has to change.
What can I share?
A part number, label photograph, drawing, datasheet, dimensional photograph, or the unit itself.
What will Micro Motion provide?
A candidate, dimensional and electrical comparison, known gaps, assumptions, and qualification plan.
When, and how?
Acknowledged in one business day. Initial recommendations returned within two business days by email.

What to send

Ranked by how much it moves the screening forward. The first line alone is enough to start.

The part number, exactly as printed
Including the suffix. A suffix usually carries the winding, the shaft and the lead configuration, which is most of the electrical identity.
A focused photograph of the nameplate or label
Both faces if the label wraps. Fill the frame with the label rather than the machine around it.
The drawing or the datasheet
Envelope, mounting pattern, shaft form and tolerance. This is what decides whether a candidate is a mechanical fit at all.
A photograph of the shaft and mounting face with a scale in frame
A rule or a caliper beside the part lets us read flat depth, shaft diameter and the pilot from the image when no drawing exists.
Measured no-load speed and current at the supply voltage
Two numbers on a bench fix the motor constant more tightly than any catalog table. They separate a worn unit from a design mismatch.
The operating point in your mechanism
Torque, speed and duty at the load. A motor is only equivalent at the point it actually runs, not at its rated point.
Annual volume and the plant it ships to
Decides stocking, configuration, sample terms and whether a tooled variant is worth proposing.

What comes back

One document, written by an engineer, against the evidence you sent. Every value carries its basis: published, calculated, typical, or not established.

  • Candidate configuration

    A Micro Motion SKU, or a configuration that is buildable but not yet published, named as such.

  • Dimensional comparison

    Body diameter and length, shaft form, mounting face, pilot, lead exit, and total installed length against yours.

  • Electrical comparison

    Rated voltage, no-load speed and current, stall torque and current, terminal resistance, and the motor constant.

  • Speed and torque at your operating point

    Not at the rated point. Where your mechanism actually loads it, with the margin stated.

  • Known differences and assumptions

    Everything we had to guess because the evidence did not say. This section is usually the most useful one.

  • Sample or prototype status

    What can ship now, what needs a build, and what needs tooling.

  • The test and qualification plan

    What has to be measured on a real sample, in your mechanism, before anyone calls this a replacement.

From initial support to qualification

Start with a candidate. Move to samples and testing when the application requires measured proof.

Row Screening The offer on this page Qualification Quoted engineering work
What happens We read your evidence, match it against published platforms and buildable variants, and write down every difference we can see.Sample build or configuration, bench measurement at your operating point, and life, noise or environmental testing to the plan we agreed.
What you receive The packet above: candidate, comparisons, assumptions, gaps, and a proposed test plan.Measured data from the actual sample, against the plan, with the test conditions recorded.
What it proves That a candidate is worth testing. Nothing beyond that.That the candidate meets the requirement in your mechanism.
What it costs No cost, and no obligation.Quoted in writing before anything is built or tested.

Start the cross-reference

The first six answers are enough. Add detail when available and we will use it to sharpen the recommendation.

Obsolescence, allocation, a lead time, a failure, a cost target, a new program, a second source.

Two or three sentences in your own words. What it has to do, and what is wrong today.

Up to 6 files, 20 MB each. Drawings, datasheets, nameplate or teardown photographs, STEP or IGES geometry, DXF, a CSV duty log, a ZIP of the set. Larger files: contact us and we will coordinate transfer.

Detail that sharpens the screening (optional)

Lead screw, belt, direct drive, cam, gear train. Include the reduction after the motor.

Diameter and length, or the box it has to fit.

Nominal, and the range at the motor terminals.

At the load, after any reduction.

Continuous and peak, at the load.

On time, off time, starts per hour, and how long a run lasts. This is what predicts temperature and life.

Hours, cycles, or units of the mechanism's own work.

dB(A), the distance, and the background level.

Encoder, hall, index, current sense, or open loop. Name the driver if it is fixed.

Ambient range, orientation, humidity, cleaning agents, sterilization, vibration, altitude.

When samples are needed, and when production starts.

Where the assembly is built and where the motor ships to.

What decides this design

Pick the constraints that actually bound the choice. It changes what we screen for.
