Product Description:

The PMB33E-10216-02 brushless servomotor is manufactured by Pacific Scientific within the PMB Brushless Servomotors series. As a permanent-magnet unit intended for closed-loop control, it supplies repeatable torque and speed to automated pick-and-place axes, indexing tables, and other production equipment that depend on precise electrical-to-mechanical power conversion under changing loads. Its compact package integrates feedback and thermal protection features, reducing the need for separate external devices around the motor. This helps the unit fit into space-limited motion systems where clean wiring and consistent feedback are important.

The mechanical envelope follows the NEMA Size 34 standard, so its mounting face and pilot diameter match common 3.4-inch square motor brackets used throughout industry. Position feedback is delivered by an optical encoder that generates 4096 ppr, allowing the controller to track rotational movement with fine resolution in velocity and position loops. During stalled conditions at 240 VAC, the windings draw up to 7.4 ARMS. Over-temperature protection is provided by an embedded PTC thermistor that changes resistance sharply near its trip point, enabling the drive to cut power before insulation temperatures are exceeded. Power, feedback, and sensor conductors exit the housing as flying leads with MS connectors, which allows field connection without opening the motor.

Commutation data is supplied through the integrated Digital Encoder with commutation, eliminating the need for separate Hall sensors and keeping sine-wave current alignment accurate as speed changes. A round shaft simplifies coupler selection and reduces stress concentrations compared with keyed alternatives. The magnetic section is built with a stack length multiple 3, which increases torque capacity without increasing the face dimensions of the motor. This brushless servomotor can be paired with compatible servo drives for responsive motion axes in automated equipment, and its integrated feedback arrangement supports stable operation during acceleration, deceleration, low-speed positioning, repeated direction changes, and stop-and-hold moves.
