Product Description:

The PMB32C-20100-00 is a brushless servomotor produced by Pacific Scientific within the PMB Brushless Servomotors series. As a closed-loop actuator, it converts drive commands into controlled rotary motion for positioning tables, indexing conveyors, or similar automation axes that demand repeatable torque at low speed. Its resolver feedback links directly to digital servo drives, making the motor a self-contained element for precise velocity and position regulation in industrial machinery.

This model occupies the NEMA Size 34 frame, so its face mounting and shaft height correspond to common U.S. flange standards, simplifying mechanical interchange. The magnetic circuit can sustain a nominal stall current of 3.8 ARMS at 240 VAC, indicating how much continuous phase current the drive must supply for rated torque without overheating. Feedback is supplied by a Resolver, which tolerates electrical noise and high temperatures better than optical encoders while still providing absolute position over a single turn. Torque is delivered through a Square Key shaft, allowing couplings or pulleys to lock to the shaft without fretting. Power and signal exit the housing on Flying leads with AMP connectors, so no mating motor-side receptacle is required and wiring can be routed through tight spaces before termination.

Because the unit is configured as a Standard Motor, it ships with the default winding and magnet set used for this frame size, avoiding lead-time penalties associated with custom options. A stack length multiple of 2 means two lamination sections are bonded inside the stator, giving a mid-range torque constant compared with shorter or longer stacks in the same diameter. Its product type is PMB Series Brushless Servomotor, and it is intended for use with matching Pacific Scientific SC or SCE drives in multi-axis assemblies that use resolver-based motion loops.
