Product Description:

The PMB33F-10201-00 brushless servomotor is manufactured by Pacific Scientific. It is designed for use with matched electronic drives and supplies rotary motion for pick-and-place heads, indexing tables, and other automated axes that need precise velocity and positioning. The unit combines a permanent-magnet rotor with electronic commutation, so it can deliver repeatable torque without brush wear in continuous-duty industrial environments. This operating method also supports smooth response during repeated start-stop cycles common in automated machinery.

The motor’s mechanical interface follows the NEMA Size 34 outline, giving a mounting face and pilot diameter that align with standard U.S. gearboxes and actuators. Power exits through flying leads with MS connectors, a wiring style that reduces cabinet depth by eliminating a rear exit plug while still accepting military-style circular mates. With a DC bus derived from 240 Vac, the phase windings can hold a steady stall current of 11.0 ARMS. Rotor position information is supplied by a Hall sensor, enabling six-step commutation in compatible drive platforms. The feedback signal gives the drive the rotor state needed to switch current to the correct phases during startup and low-speed operation. A round shaft permits direct coupling to belts, pulleys, or collets without keyseat machining.

To extend torque without increasing frame diameter, the design uses a stack length multiple of 3, adding laminations while keeping the same mounting pattern. Because it is supplied as a Standard Motor, the unit does not include custom windings or special seals. The motor belongs to the PMB Brushless Servomotors series. The longer lamination stack increases active material while preserving the standard outline used by this frame size. That arrangement keeps the motor compact at the mounting face while providing more magnetic length inside the housing.
