BLM-N23-50-1000
M O T O R S / D R I V E S
Brushless Servo Motor
Product Description
The BLM-N23-50-1000 brushless motor with incre-
mental encoder is a low cost, high performance
motor well suited for OEM applications.This motor
has a high torque to inertia ratio making it ideal
for point-to-point applications requiring fast accel-
eration.The BLM-N23-50-1000 provides 46 oz-in of
continuous torque in a Nema 23 frame size package.
