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.

Introduction to Stepper Motors and Drives
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
