Product Description:
The PMB33E-10116-00 brushless servo motor is produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop velocity and position control, this unit couples directly to gearboxes or machine shafts, delivering consistent torque in automated assembly, packaging, and pick-and-place cells. It integrates an internal digital feedback device and a phase-wound stator, allowing the accompanying drive to modulate current precisely for smooth motion. Its rare-earth magnets sustain flux at elevated rotor speeds, supporting dynamic indexing and rapid reversals.
At continuous stall, the motor develops 5.42 Nm (48.0 lb-in), providing a baseline for load matching when airflow is limited and the rotor is locked. The frame follows the NEMA Size 34 outline, so mounting holes and pilot diameter align with common U.S. servo brackets. When energized from 240 VAC, a nominal stall current of 7.4 ARMS is required, so drive sizing must account for cable ampacity and power-stage rating. The integrated digital encoder with commutation supplies sinusoidal tracks and an index pulse, while its resolution of 4096 ppr enables precise interpolation for sub-arc-minute positioning in electronic camming and accurate machine registration cycles.
The electrical interface is provided through flying leads with AMP connectors, so the motor can be connected without a plug mounted on the motor housing. A round shaft transmits torque without keyways, favoring clamp couplings that minimize concentricity error. Pacific Scientific ships this unit as a standard motor, meaning no special winding or seal modifications have been applied. A stack length multiple of 3 increases the active iron volume within the same frame size, which raises torque density while keeping inductance low for rapid current transitions.
