Stepper motor analyzer

[kristinj]

I am trying to find suppliers of motor analyzers for small stepper motors. In particular, I want something that can measure detent torque as well as pull-in and pull-out torques. Any suggestions would be appreciated. Thanks!

There are several manufacturers of these testers.

Vibrac in Amherst NH is probably the best known. They have lab or production systems that can measure motors with a wide range of inertia matching. (expensive but good)

Magtrol has equipment that can do the job.

Also, a company in the Chicago area (S. Himmelstein) has some excellent equipment. I used their modules to build a custom system for a company I was working with in Korea.

Ther are a couple of offshore (Japanese) sources also. These are quite good.

You need to consider;
1. Cost
2. Speed of test
3. Accuracy. Detent can be accomplished with a Torque watch, but will ony give the high readings.

Good luck!
