Q: I'm looking for more mechanical specifications of your BLH series brushless motor output shafts. I'm working on a pretty sensitive motor application where the load cannot move much. Can you provide me the shaft run-out, the radial play, and the axial play?

A: Since we use the same ball bearings and shafts from our PK series step motors, these specifications should be the same for our brushless motors.

Shaft Runout
0.05 mm (0.002 in.) T.I.R.
0.075 mm (0.003 in.) T.I.R.
0.075 mm (0.003 in.) T.I.R.
Radial Play
0.025 mm (0.001 in.) maximum of 5 N (1.12 lb.)
Axial Play
0.075 mm (0.003 in.) maximum of 10 N (2.2 lb.)

This information is valid for PKP and PKE series stepper motors as well.
