Product Description:

The PMB32E-20114-00 is a brushless servomotor produced by Pacific Scientific and offered within the PMB Brushless Servomotors series. Designed for closed-loop motion axes in packaging lines, pick-and-place robots, and semiconductor tooling, the unit converts controlled electrical input into precise mechanical rotation. Its permanent-magnet rotor and electronic commutation allow rapid torque modulation, helping the motor support tight position tolerances and high throughput in automated machinery. This makes it suitable for indexing, transfer, and placement tasks that require consistent response during frequent speed changes.

The mechanical frame follows the NEMA Size 34 standard, so the motor bolts directly to gearheads or brackets that support 86 mm square flanges. Incremental feedback is generated by a 2048 ppr optical encoder, so each revolution produces 2048 pulses for position tracking. Under worst-case loading, the continuous stall current is limited to 7.4 ARMS when the drive is supplied with up to 240 Vac, which helps with thermal planning and cable selection. Power and signal conductors leave the housing as flying leads with AMP connectors, simplifying connection to matching hardware. For mechanical coupling, the output shaft uses a square key seat that transmits torque through standard keyed hubs.

For controllers that expect simultaneous position and commutation data, the motor includes a digital encoder with commutation. This dual-track sensor supplies both incremental counts and commutation sequences so the inverter can energize the correct phase immediately after power-up. Because it is delivered as a standard motor, the unit uses factory-set winding and feedback options that match common drive parameters. It belongs to the PMB Series Brushless Servomotor group, and the lamination stack uses a stack length multiple of 2, which provides an intermediate power option without changing the mounting footprint.
