Product Description:

The PMB33F-00200-00 is a brushless servomotor manufactured by Pacific Scientific and assigned to the PMB Brushless Servomotors series. As a rotary actuator, it converts drive current from a matched amplifier into precise mechanical motion, supplying closed-loop speed and position control for conveyor sections, pick-and-place heads, and similar automated stages. Its electromagnetic design supports rapid reversals and high repeatability, making it suitable for tightly synchronized industrial automation tasks. The motor is intended for applications that need accurate response during repeated starts, stops, and direction changes.

Physical interface follows NEMA Size 34 frame conventions, allowing direct installation in gearboxes or mounts designed for that footprint. Power exits the housing through flying leads with MS connectors, so field wiring can be completed while preserving the connector seal. At a 240 V AC bus, the motor can produce a nominal stall current of 11.0 ARMS. This is the current the drive must supply when the rotor is locked and rated torque is required. Rotor position feedback is delivered by a resolver, providing analog sine-cosine signals that withstand electrical noise better than digital encoders. Mechanical coupling is provided by a flat shaft, which gives a positive drive surface for set-screw couplings without the added cost of a keyed output.

The magnetic circuit is built on a stack length multiple of 3, which increases active iron volume and raises torque compared with shorter stacks of the same frame. Because the unit is supplied as a standard motor, it does not include custom windings or special seals. This keeps the motor in a standard PMB configuration for general industrial motion service. The overall arrangement supports consistent operation in systems that require stable rotary response and repeatable positioning.
