Full JR code
Use the full JR16M4CH, JR24M4CH or JR25M6CH designation from the plate, including every option suffix. Short family names alone leave the build scope unresolved.
JR-series ServoDisc
Kollmorgen / PMI JR16, JR24 & JR25 Retrofit Review
Review an existing JR-series machine axis as a motor, feedback and support-bearing system. The suffix, brake package and driven load must stay visible when assessing a replacement.

Ruggedized assembly, brake and support loads
Information that determines the JR-series ServoDisc review
Bearing and coupling loads
Provide the coupling arrangement and radial, axial or overhung load. The replacement review must retain the machine load path and bearing responsibility.
Brake assembly
Record brake voltage, holding duty, release behaviour and added length. Distinguish the holding brake requirement from the machine stopping strategy.
Tachometer or encoder
Photograph the feedback housing and connector and record its electrical interface. Similar external packaging does not establish the same feedback signal.
Duty and acceleration
Provide the load cycle, maximum speed, repeated acceleration and available cooling. Review current and inertia against the installed amplifier before choosing a retrofit architecture.

Find a legacy motor reference.
Search the model, a family abbreviation or manufacturer. A result identifies equipment for review; every replacement proposal still needs mechanical, electrical and duty validation.
5 identification references. Status: engineering review required. Supply and current OEM availability are unconfirmed.

Have a different suffix or unreadable plate?
Send the exact code or a controlled photo link. The absence of a search result does not prevent an industrial identification request.

Questions about this identification route
Is a JR16 family name enough to identify a motor?
It is a useful starting point. A final review needs the full model and suffix, option package, interface photographs and drive information.
Can the existing brake and gearbox remain?
That is a project-specific review item. Supply their mounting and operating requirements so the proposed scope identifies exactly which parts are retained or replaced.
Check the source and the installed motor together.
Source documents identify legacy products. Actual option packages, application suitability, lifecycle status and replacement compatibility require confirmation for the complete nameplate code.
