Product Description:

The PMB33F-10200-02 is a brushless servomotor produced by Pacific Scientific and delivered within the PMB Brushless Servomotors series. Intended for closed-loop industrial automation, it converts electrical power into tightly regulated rotary motion for axes such as feeders, indexing tables, and compact gantries. When paired with a matched digital drive, the unit supports rapid index moves, velocity control, and torque regulation required in electronic assembly, packaging, and material-handling equipment. Its construction is suited for continuous-duty operation in multi-shift production environments where repeated starts, stops, and speed changes are common.

Under stall conditions, the winding set is rated for 11.0 ARMS, so the drive must supply that current while managing overload protection. This value assumes a DC bus derived from a 240 Vac three-phase supply, which affects upstream power distribution and circuit protection. The motor body conforms to NEMA Size 34 dimensions, so it fits machine layouts that use this standard flange and pilot pattern. Power and feedback leads emerge as flying leads, and assembly is completed with field-attachable MS connectors that support secure external termination and flexible cable routing. This arrangement is useful where cabinet wiring must be routed through tight spaces or around moving machine members.

Rotor angle is captured with a resolver, an analog feedback device chosen for wide speed range and strong noise immunity. Output torque is delivered through a round shaft, allowing clamp or compression couplings when a keyed connection is not required. Thermal safeguarding relies on an embedded PTC Thermistor, whose resistance change allows the drive to reduce output before winding hot spots develop. The electromagnetic core uses a stack length multiple of 3, which extends the lamination stack and raises continuous torque without changing the outer frame. These electrical and mechanical features make the motor suitable for precise motion control where stable feedback, compact mounting, and dependable thermal protection are important.
