Omegamation™ offers a robust line of 2-phase biploar step motors ranging in frame size from NEMA 11 to NEMA 34. Most of our models are the high torque style, with holding torques up to 1845 oz-in. All motors conform to industry-standard NEMA mounting dimensions, and are offered with a range of well-featured, compatible drives and indexers. With the exception of our two smallest motors (OMHT11-013, OM5014-842), all of our step motors are optimized for microstepping: they can achieve a stepping resolution of up to 51,200 steps/revolution (.007° per step) when operated by one of our microstepping drives. In addition, these motors can be operated in a closed-loop system for even more precise position control when fitted with one of our incremental encoders.

All of the stepper motors sized from NEMA 17 through NEMA 34 are 8-lead motors, offering the flexibility of either series or parallel connection. The motors should be series connected for best torque at low speeds, and parallel connected for best torque at higher speeds.

Motor Wiring --- Parallel Connection (8-lead motors):
Drive A+ = Orange + Black/White
Drive A- = Black + Orange/White
Drive B+ = Red + Yellow/White
Drive B- = Yellow + Red/White

Motor Wiring --- Series Connection (8-lead motors):
Drive A+ = Orange
Drive A- = Black
Drive B+ = Red
Drive B- = Yellow
Connect Orange/White to Black/White (not connected to drive)
Connect Red/White to Yellow/White (not connected to drive)

Motor Wiring (4-lead motors):
Drive A+ = Red
Drive A- = Blue
Drive B+ = Yellow
Drive B- = White
