Product Description:

The PMB33F-00216-00 brushless servomotor is produced by Pacific Scientific as part of the PMB Brushless Servomotors series. It converts electrical energy into controlled rotary motion for axes that require tightly regulated torque and speed in automated machinery. In packaging lines, indexing tables, or small gantry stages, the unit works with a servo drive to position loads quickly and repeatably. Because it is intended for closed-loop servo operation, it can support both point-to-point moves and steady speed regulation on the same axis. That makes it suitable for machines that must settle at target positions without excessive overshoot during short production cycles.

The motor body follows the NEMA size 34 frame standard, so its face mounting dimensions match common compact machine layouts. A feedback device with 4096 ppr resolution is integrated, and the motor uses a digital encoder with commutation so the drive receives both position data and phase information for startup and closed-loop control. This arrangement supports accurate speed correction and repeatable position updates throughout motion. When the shaft is stationary, the winding can sustain 11.0 ARMS at 240 VAC before thermal limits are reached, which helps determine suitable drive current capacity and enclosure airflow. Power, signal, and ground conductors exit as flying leads with MS connectors, which simplifies connection where matching receptacles are already installed.

The motor has a flat shaft, which is commonly used with clamp or setscrew hubs in compact assemblies. The shaft form keeps the coupling arrangement simple in applications that do not need a keyed connection. Its electromagnetic section uses a stack length multiple of 3, adding active material for higher continuous torque without changing the mounting footprint. The unit is supplied as a standard motor, so it uses standard magnet and insulation materials rather than special options. With its compact frame and integrated feedback, the motor can fit into dense multi-axis layouts where cable space and mounting area are limited.
