The document introduces the HO series NEMA 23 brushless motors from Applimotion for precision direct drive applications. The motors feature a large through hole, NEMA 23 mounting flange, high performance magnets, and optional windings. They provide sinusoidal torque curves, high resolution encoders up to 29 million counts per revolution, and are designed to replace geared mechanical stages for better accuracy and reliability. Key specifications for motor model 63-B-44-A are listed.

1. “Precision, Accuracy
and Resolution of a
direct drive rotary
stage packaged in a
standard motor frame”
Applimotion Inc. (www.applimotion.com) introduces the
HO series NEMA 23 brushless motors with large
through hole for precision Direct Drive applications.
Features:
Large Through Hole – 16 mm axial through
hole with optional shaft extensions available.
NEMA 23 Mounting Flange – Industry standard
for step motors and servo motors.
NdFeB Magnets - High performance single ring
multi-pole magnet.
Optional Windings – Select your voltage,
speed and current, we create the winding.
Sinusoidal Torque Curves – less than 1%
higher harmonic content for minimum torque
ripple on sinusoidal drives
High Resolution Encoder– Standard Encoder
Resolution 288,000 counts/rev, optional
resolution up to 29,492,200 counts/rev.
Designed for Direct Drive Rotary
Applications Replace geared mechanical
stages with better accuracy, higher reliability,
quiet operation, and longer life.
