Product Description:

The PMB33F-10116-00 is a brushless servomotor produced by Pacific Scientific. It works with servo drives to provide tightly regulated torque and speed in equipment such as pick-and-place gantries, indexers, light machining centers, and material-handling lines. By combining permanent-magnet excitation with embedded feedback sensing, the motor supports closed-loop positioning and stable velocity control in industrial automation. This arrangement allows the drive to track command changes quickly while maintaining smooth rotary motion under varying load conditions. Because feedback is built into the motor, the drive can correct speed and position errors as the axis accelerates, decelerates, or changes direction.

On a 240 VAC bus, the winding can sustain a nominal stall current of 11.0 ARMS, which indicates the continuous phase current a matched drive must supply while the rotor is held under load. Rotor position is reported by an integrated encoder with 4096 ppr, so the controller receives 4,096 incremental pulses per revolution for accurate motion feedback. Power, sensor, and ground conductors exit the housing as flying leads with AMP connectors, which allows direct connection to a mating harness. The frame uses the NEMA Size 34 mounting pattern, so it fits a 3.4-inch square face common in many servo installations. Commutation is handled by a digital encoder with commutation, which removes the need for separate Hall sensors and simplifies motor feedback wiring. This setup reduces the number of separate motor components and keeps external cable routing simpler inside compact machine assemblies.

This model is supplied as a Standard Motor, so it uses the baseline winding and mechanical arrangement for this motor line. The shaft is round, which means couplings rely on clamp hubs or other external locking methods rather than an integral keyway. Magnetic output is scaled by a stack-length multiple of 3, increasing torque capacity over shorter stack lengths without changing the mounting face. The motor belongs to the PMB Brushless Servomotors series, which places it within the same product line as related motors. That combination suits general-purpose axis applications that need predictable installation and conventional coupling hardware.
