Product Description:

The PMB33C-10201-00 is a brushless servomotor produced by Pacific Scientific and included in the PMB Brushless Servomotors series. As a permanent-magnet, three-phase actuator, it converts electrical power from a matched servo drive into controlled torque and speed for indexing tables, pick-and-place axes, and other motion tasks in industrial automation cells. Its electromechanical design supports closed-loop control for precise position commands and repeatable motion in compact machinery. Because commutation is handled by the servo drive, the motor can respond quickly to acceleration, deceleration, and direction changes while maintaining stable rotary output.

At the mechanical interface, the motor follows the NEMA Size 34 flange pattern, so it aligns directly with gearheads and brackets that share this standardized 3.4-inch square frame. Under locked-rotor conditions at 240 VAC, the winding draws 3.8 ARMS, which helps size the drive current loop and associated cabling. Rotor position feedback is provided by a Hall sensor, enabling six-step commutation and supporting controllers that do not require encoder-level resolution. Motion is transmitted through a round shaft, which simplifies coupling to clamps, timing pulleys, or collets instead of keyed connections used for heavier torsional loads.

Electrical termination uses flying leads with MS connectors, allowing direct connection to cabinet wiring without a terminal box on the motor housing. Cable strain relief must be arranged inside the cabinet because the conductors leave the motor as flexible leads rather than through a fixed conduit entry. The rotor uses a stack length multiple 3, which provides more active length than shorter versions in the same frame size. The unit is a standard motor with no custom modifications, so it keeps the baseline winding and magnet arrangement for this model.
