Product Description:

The SR3632-8292-7-56BC-CU is a permanent-magnet DC motor from Pacific Scientific in the Permanent Magnet DC Motors series. It provides continuous rotary power for actuators, conveyors, and compact machine drives where precise speed control is required. Within an automation cell, the unit couples to a compatible DC drive to move loads smoothly and maintain commanded velocity under varying mechanical demand.

The motor uses a rated supply of 90 VDC and produces a nominal shaft speed of 1750 RPM. At this operating point, the armature draws 3.5 A and delivers 12.0 lb-in of continuous torque for steady-state duty. Short acceleration or overload events can be handled because the peak armature current reaches 71.0 A. Electrical resistance of 1.8 Ω and inductance of 6.6 mH affect the current-loop response, allowing the drive to keep ripple and overshoot under control. The 56C NEMA face with a 4.500 in pilot lets the motor bolt directly to standard gearheads, and the face orientation keeps the keyed shaft aligned with the driven element without additional adapters.

The output is rated at 1/3 HP, which is appropriate for small material-handling stages that run continuously on production shifts. Each ampere above idle contributes roughly the same torque because of the 3.9 lb-in/A torque constant, so drive tuning can remain linear across the working range. The totally enclosed, non-ventilated construction is identified by the TENV enclosure code and helps prevent airborne debris from entering the frame. Overall unit mass is kept to 21 lb, and length is limited to 10.13 in so the motor fits where cabinet depth is restricted. A 0.6250 in shaft with a 0.188 × 1.38 in key transmits torque while maintaining positive coupling to pulleys or couplings without fretting.
