Product Description:

The PMB33E-00116-00 brushless servomotor is produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for industrial automation, the unit supplies controlled torque and speed to conveyor sections, pick-and-place heads, and indexing tables that rely on precise closed-loop motion. It converts three-phase drive output into rotor movement while feeding back position data so the controller can maintain tight velocity regulation. Because it shares a NEMA 34 footprint and uses flying-lead terminations, the motor fits standard mounting plates and common cable-entry layouts with minimal mechanical changes.

With a frame classified as NEMA Size 34, the motor matches the mounting pattern of other size-34 devices. Rotor position is reported by an optical encoder that delivers 4096 ppr, giving fine resolution for smooth low-speed control. The feedback device is a digital encoder with commutation, so incremental position data and three Hall tracks share one disk. Continuous torque is supported by a nominal stall current of 7.4 ARMS when powered from a 240 VAC bus, and the selected drive must accommodate that current at lock. Power and feedback exit through flying leads with AMP connectors, which simplifies wiring by removing the need for a barrel-type plug on the housing.

The output shaft uses a flat shaft surface rather than a keyway, giving a simple interface for set-screw hubs while keeping diameter minimal. Magnetic stack height follows a multiplier of 3, which indicates the longest lamination stack in this frame and supports higher continuous torque than shorter stack lengths. The unit ships as a standard motor, so no custom windings or special seals are included. It is a PMB series brushless servomotor, and it works with Pacific Scientific drives that read the Hall pattern and incremental channels without adapters.
