Product Description:

The PMB33F-10201-01 brushless servomotor is built by Pacific Scientific within the PMB Brushless Servomotors series. It serves as a permanent-magnet rotary actuator that converts regulated stator current from a servo drive into accurate mechanical motion for indexing tables, packaging lines, and pick-and-place axes in industrial automation. By eliminating brushes and using electronic commutation, the motor maintains torque repeatability and reduces maintenance compared to brushed designs. The brushless layout also helps preserve consistent response during repetitive start-stop cycles where stable torque delivery is important.

It occupies the footprint of NEMA Size 34, so it installs directly into standard 3.4-inch square mounts on machinery. Power and feedback exit the housing through flying leads with MS connectors, combining quick cable replacement with secure threaded coupling. Rotor position is provided by an integrated Hall sensor, giving the drive the commutation timing required for controlled current operation. A round shaft simplifies coupling to gearheads or pulleys without additional machining. Under locked-rotor conditions, the windings can carry 11.0 ARMS at 240 Vac maximum. This current limit sets amplifier thermal sizing and allowable duty cycle during stall or very low-speed operation.

For environments where oil spray or dust could migrate along the shaft, the motor can be supplied with a shaft seal that blocks contaminant ingress into the front bearing. Torque capability scales with lamination height, and the stack length multiple of 3 indicates three standard lamination sections. This gives the motor greater continuous torque than shorter variants in the same frame size. The unit is identified as a PMB Series Brushless Servomotor, which places it within the same magnetic and insulation platform used across the line.
