Product Description:

The PMB33F-00216-01 is a brushless servomotor built by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop motion modules, it converts electrical power into precise rotary movement, allowing automated equipment to position loads quickly and repeatably in industrial assembly cells. Its permanent-magnet rotor and electronic feedback allow the drive to maintain accurate velocity and torque control during acceleration, deceleration, and holding. This operating profile suits pick-and-place gantries, compact indexers, and small packaging axes that require stable motion through repeated cycles.

The motor frame conforms to the NEMA Size 34 outline, so mounting holes and shaft height align with common gearheads and slide adapters. Position feedback is delivered by a 4096 ppr incremental signal, and the digital encoder with commutation provides phase information so the drive applies current at the correct electrical angle. A nominal stall current of 11.0 ARMS at 240 VAC indicates the continuous phase current the amplifier must supply when the rotor is locked under rated load. Power and signal conductors exit as flying leads with MS connectors, which helps cable routing in compact machine spaces and supports separation of motor and feedback wiring.

The output shaft has a flat, so clamp-style couplings can transmit torque without a keyed connection. To protect the front bearing area from coolant or dust, the motor is supplied with a shaft seal, which helps limit contaminant entry in washdown or abrasive environments. The electromagnetic section uses a stack length of 3, increasing copper volume and supporting higher continuous torque than shorter versions of the same frame. That longer active section also helps the motor handle repeated starts and stops on compact axes where steady thermal performance is important.
