Product Description:

The PMB32D-00101-03 is a brushless servomotor built by Pacific Scientific for the PMB Brushless Servomotors series. Within industrial automation, it functions as a powered actuator, transforming three-phase electrical input from a compatible drive into precise rotational motion for conveyor sections, small gantries, and indexing equipment. Direct coupling to motion controllers allows closed-loop velocity and position control without the commutator wear associated with brushed motors. This operating approach supports repeatable starts, stops, and speed changes in continuous-duty production lines.

Mechanical interface follows the NEMA Size 34 pattern, so the frame mounts to a standardized 2.75-inch square pilot and shares bolt spacing common to many stepper and servo stages. Thermal loading is governed by a nominal stall current of 5.4 ARMS at 240 VAC, which is the maximum continuous current the windings can endure without exceeding insulation limits. Commutation feedback is delivered through an integral Hall sensor, enabling trapezoidal or sinusoidal control schemes in the drive. Power and signal conductors exit the housing as flying leads with AMP connectors, which remove bulkier flange sockets and help routing in tight cabinets.

The laminated iron core is built to a stack length multiplier of 2, yielding a mid-range torque constant that balances acceleration against inertia for mid-weight payloads. A flat shaft end allows rigid clamping hubs or pulleys to grip the rotor without keys, reducing component count. Environmental and safety provisions include a shaft seal that restricts dust and liquid entry at the front bearing and a PTC thermistor embedded in the windings so over-temperature trips can be set in the drive. They support use where airborne contamination or rising winding temperature could interrupt operation.
