Cycloidal Ball Reducers
High precision zero backlash reducers are coupled with the MYCOM STAR BIPOLAR DRIVE high performance stepping motor/driver system for and easy out-of-the-box installation

In-line style saves space

Over 1,389 oz-in running torque at 60 rpm and above

Up to 20,000 steps of true resolution (standard ratio)

+/- 15 arc seconds repeatability

5-phase stepping motor sizes from NEMA 17 to Metric 34, final holding torque from 375 oz-in (size 17 motor) to 2,776 oz-in (size 34 motor)

Highly cost effective

MYCOM's 5-phase stepping motor system has proven its superior capabilities over the standard 2-phase microstepping motor systems in many recent applications.

Now the powerful 5-phase motors are available with zero backlash cycloidal ball reducers to offer resolution of up to 20,000 highly accurate mechanical steps per revolution, as well as a large gain in maximum running torque from any given motor size.

Coupled with a high performance 5-phase motor, this unit can be implemented to your system to move any given load at a high velocity, unlike any other reduction system to this date.
