Wide Range

Sizes!
OMEGA 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 wellfeatured, 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
(0.007° 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.
8-lead motors offer 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.
All models shown
smaller than actual size.
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
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)
(4-lead motors):
Drive A+ = Red
Drive A- = Blue
Drive B+ = Yellow
Drive B- = White

MOTION INSTALLATION TIPS
l Mount the motor securely
against a surface with good
thermal conductivity such as
steel or aluminum
l Properly align the motor
with the load using a
flexible coupling
l Protect the motor shaft from
excessive thrust, overhang and
shock loads
DESIGN TIPS
l Series connect lead wires for
best torque at low speeds
l Center tap to end or parallel
connect lead wires for best
torque at higher speeds
l Keep motor case temperature
below 100°C. This can be
achieved by lowering the motor
current or limiting the duty cycle
l Allow sufficient time to
accelerate load
l Size motor with 100% safety
factor for required torque
@ speed
l Do not disassemble motors.
A significant reduction in motor
performance will result
l Do not disconnect motor from
drive while in operation
l Do not use holding torque/
detent torque of motor as
fail-safe brake

MODEL NO. DESCRIPTION
ENC-1000i Differential e
ENC-1000i-23
ENC-1000i-34 Differential encoder for NEMA 34 motors, 1000-line, with index pulse
ENC-CA-4217-6FT Encoder cable, 2 m (6')
ENC-CA-4217-10FT Encoder cable, 3 m (10')
ENC-CA-4217-20FT Encoder cable, 6 m (20')
ENC-ZAA Differential encoder for ST and STAC6 drives, NEMA 23/24 motors, 2000-line, with index
ENC-YAA Differential encoder for ST and STAC6 drives, NEMA 34 motors, 2000-line, with index
ENC-ST-CA-10 Encoder cable for ST and STAC6 drives, 3 m (10')
Encoders offered are differential encoders with line drivers. These provide two channels of signals with complementary
signals. Versions with index also offer Z-channel and its complementary signal. Remember that a double shaft motor is required.
Ordering Examples: OMHT17-075-D NEMA 17 high torque step motor with 62.8 oz-in min holding torque and double shaft.
ENC-1000i 1000-line encoder with index pulse for NEMA 17 motor, and ENC-CA-4217-10FT 3 m (10') encoder cable.
ST/STAC6 Encoder Option:
Use encoder ENC-ZAA for ST5-Si, ST10-Si, and STAC6-Si drives with NEMA 23 motors.
Use encoder ENC-YAA for ST5-Si, ST10-Si, and STAC6-Si drives with NEMA 34 motors.
The ENC-ST-CA-10 cable connects the optional encoders listed above to the ST and STAC6 series drives.
