Product Description:

The PMB33C-10201-03 is a brushless servomotor manufactured by Pacific Scientific as part of the PMB Brushless Servomotors series. It is intended for closed-loop industrial automation where rapid torque response and repeatable positioning are required. By pairing with a suitable drive, the motor converts electrical energy into controlled mechanical rotation, making it useful for indexing tables, pick-and-place axes, or medium-torque machine tools.

A frame size of NEMA Size 34 sets the mechanical envelope and mounting bolt pattern, allowing the motor to fit many existing 34-frame installations. At 240 VAC, the motor has a nominal stall current of 3.8 ARMS, which helps match it with a compatible drive during continuous holding duty. Rotor position is detected by an integrated Hall sensor, supplying commutation feedback to the controller for electronic switching. Electrical termination is provided through flying leads with MS connectors, which supports flexible routing while preserving a sealed circular connector interface at the cabinet boundary. Mechanical output is delivered through a round shaft, which simplifies coupling to gears, timing pulleys, or flexible couplings because no keyway alignment is required.

Torque density is increased by a stack length multiple of 3, meaning three lamination stacks extend the active magnetic path without changing the frame diameter. Environmental protection is improved by the factory-installed shaft seal and PTC thermistor; the seal limits contamination at the output end, and the thermistor provides temperature feedback for overload protection. The added thermal monitoring supports protective shutdown by the paired drive when winding temperature rises. Produced by Pacific Scientific, the motor remains part of the PMB Brushless Servomotors series.
