Product Description:

The PMB32B-00114-00 is a brushless servomotor produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. It is intended for closed-loop position and velocity tasks inside industrial automation cells, where precise electrical commutation and compact frame dimensions are required to drive rotary actuators, indexing tables, or small gantry axes. Its compact design supports accurate motion control in equipment that must respond quickly to changing command signals.

It is built around a NEMA Size 34 frame, which provides consistent face mounting and shaft height across compatible gearboxes and fixtures. The integrated digital encoder delivers 2048 ppr feedback, enabling the drive controller to resolve fine angular movement for tight motion loops. Power is supplied through flying leads with AMP connectors, so the motor can be wired directly into harnesses without additional terminal blocks. Rotor position and commutation data are derived from a digital encoder with commutation, allowing the controller to energize the three-phase windings in the correct sequence at every speed. During sustained standstill at the rated 240 VAC bus, the windings can carry 2.7 ARMS of nominal stall current, indicating the continuous torque threshold before thermal limits are approached.

The mechanical interface uses a flat shaft end that simplifies coupling to pulleys or precision clamps without keys. Rotor length uses a stack length multiple of 2, balancing inertia against output torque for mid-range servo duties. Because the unit is supplied as a standard motor, it does not include customer-specific winding or flange modifications. Its designation as a PMB Series brushless servomotor indicates electronic commutation and permanent-magnet construction. These features reduce maintenance needs and support fast response compared with brushed motor designs.
