Product Description:

The PMB33E-10214-00 is a brushless servomotor produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop industrial axes, the motor converts drive current into controlled rotary motion suited for pick-and-place, packaging, and material-handling equipment. It is intended for applications that require repeatable speed and position control during continuous machine cycles. Because the motor is brushless, there are no brush contacts to wear during normal operation, which helps maintain consistent commutation over long production runs.

With a frame classified as NEMA Size 34, the motor uses the mounting dimensions common to size-34 devices on standard machinery. Its shaft is Round, so couplings can slide on without keyways when precise concentricity is required. Power and feedback exit the housing through Flying leads with MS connectors, an arrangement that allows quick mating to turret-type receptacles while maintaining vibration resistance. The lead-and-connector arrangement also gives cable routing flexibility when the motor is installed in confined machine spaces. Rotor position data is supplied by an optical encoder that generates 2048 ppr, giving the drive 2048 discrete counts per revolution for fine velocity and position control. During static load conditions, the winding can draw up to 7.4 ARMS at 240 VAC, a value used when sizing the drive amplifier and cabinet wiring.

The feedback device is identified as a Digital Encoder with commutation; commutation tracks embedded inside the code wheel let the drive derive phase information without external Hall sensors. This arrangement helps the controller maintain smooth torque production through acceleration and low-speed operation. The encoder signal supports stable interpolation, accurate stopping, and controlled speed changes during repeated indexing moves. The motor is supplied as a Standard Motor, so it uses the regular winding and flange arrangement for this product line. Pacific Scientific designates the active magnetic stack as a multiple of 3, indicating the third length option in the family and a higher torque constant than shorter stacks. The motor is classified as a PMB Series Brushless Servomotor and follows the PMB electrical and mechanical format used with compatible drives and accessories.
