Product Description:
The PMB33F-10201-02 is an AC brushless servomotor produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop motion axes, the motor converts electrical energy into controlled torque and speed for pick-and-place units, indexing tables, and other positioning tasks in automated machinery. Its compact build allows direct mounting to NEMA 34 gearboxes or load couplings, which helps keep the drive train short in space-limited equipment. Integrated Hall sensors supply commutation data to digital drives so the system can maintain accurate rotor synchronization as load conditions change.
The frame is classified as NEMA Size 34, which corresponds to a 3.38-inch square flange that matches standard servo gearheads and supports direct mounting. During stall at 240 VAC, the winding can sustain a nominal current of 11.0 ARMS, so the drive must supply that level continuously when the axis holds position. Rotor position feedback comes from a Hall sensor, which sends three digital signals for six-step electronic commutation. A round shaft eliminates keyways and supports clamp couplings that help minimize concentricity error. Power and feedback exit through flying leads with MS connectors, allowing quick connection to compatible drive wiring. That arrangement also keeps the cable exit compact where the motor is mounted close to guards or frame members.
Torque density is increased by the laminated core's stack length multiple of 3, which provides more active magnetic material than shorter versions without changing the mounting outline. Winding protection is provided by a built-in PTC thermistor, and the drive can monitor its resistance to reduce current or stop the axis if internal heat rises too far. The common connector style and Hall-based feedback arrangement support use with compatible servo amplifiers that expect commutation signals together with a thermal input. This keeps motion feedback and temperature monitoring inside the same motor envelope while leaving the shaft end and mounting face free for the mechanical connection.
