Find why the motor or gearbox failed.

Noise, heat, current, brush wear, gear damage, endplay, inconsistent life, locked-rotor damage. The failure mechanism has to be found before a replacement means anything.

Is this the problem I have?: Units are noisy, hot, intermittent, damaged, or failing too early, and the mechanism is unknown.
What evidence can I give?: The failed unit untouched, its duty, failure rate, life point, symptom, supply, and ambient conditions.
What does Micro Motion return?: Initial engineering guidance, followed by a priced teardown only when physical analysis is the right next step.
When, and how?: Acknowledged in one business day. Nothing ships, opens, or incurs cost before written approval.

Describe the failure

Failure analysis options

Start with the available evidence, then choose the level of analysis that will answer the engineering question.

Row Intake and plausibility review Free Teardown and root-cause analysis Quoted engineering work

What happens We read the symptom, the duty and the photographs, and reason about which failure mechanisms are consistent with them.Chain of custody, incoming inspection, electrical characterization before disassembly, controlled teardown, dimensional and wear measurement, photography at magnification, and root-cause reasoning against the duty.

What you receive A written plausibility review: likely mechanisms, ruled-out mechanisms, and what would have to be measured to separate them.A root-cause report with the measurements, the photographic record, the corrective options, and the sample or requalification plan. Evidence is retained for an agreed period.

What it proves Whether a physical teardown would answer your question, or whether the answer is already in the duty profile.What actually failed, in what order, and whether a different motor would survive the same duty.

What it costs No cost.Quoted in writing before the unit ships. The unit is destroyed by a teardown; that is agreed in advance.

When Acknowledged within one business day.Set by the analysis plan you approve.

What to tell us

The unit answers what broke. Only you can answer what it was doing when it broke.

The symptom, in the words the technician used: Noisy, hot, slow, stalled, intermittent, dead. The first description is usually more accurate than the diagnosis that follows it.
How many failed, out of how many built: One in five thousand and one in four are different problems with different causes. A rate turns a story into data.
How far into life it failed: Hours, cycles or units of the mechanism's work. Infant mortality, a wear-out curve and a random rate each point at different mechanisms.
The duty profile it actually ran: On time, off time, starts per hour, direction reversals, and whether it is ever stalled against a hard stop. Reversals and stalls end more motors than continuous running does.
The supply at the motor terminals: Nominal voltage, the real voltage under load, and whether it is PWM. Ripple, switching frequency and inrush all show up in brush and commutator wear.
Ambient and mounting: Temperature range, orientation, enclosure, and what the motor is bolted to. A sealed enclosure at 55 degrees C is a different motor problem than a bench at 22.
Photographs before you pack it: The label, the shaft end, the lead exit, and anything visibly wrong. Photograph it in the mechanism if it is still installed.
What changed: A new supply, a new lot, a new mold, a new grease, a firmware change to the ramp, a new plant. Failure that starts on a date usually has a cause with the same date.

How the work runs

Ten steps, and the first six happen before a unit is opened.

Intake

You describe the failure and the duty here. Nothing ships yet.
Confidentiality terms

Signed before drawings, process detail or failure data changes hands, if your terms require it.
Plausibility review

Free. What the symptom is and is not consistent with, and whether a teardown would answer it.
Analysis plan and quote

What will be measured, what is consumed during teardown, what it costs, and the expected timing.
Shipping instructions

How to pack it so the evidence survives transit, and where to send it.
Chain of custody

Logged on receipt: what arrived, in what condition, photographed as received, held under a project identifier.
Inspection authorization

You confirm the analysis plan before the first destructive step.
Teardown and measurement

Electrical characterization first, then controlled disassembly with dimensional, wear and photographic records at each stage.
Findings review

Walked through with your engineers, with the measurements in front of both sides.
Corrective options and sample plan

What would change the outcome: duty, drive, mounting, configuration, or a different motor. With the test that would prove it.
