Product Description:

The PMB32D-00101-01 is a brushless servomotor built by Pacific Scientific and part of the PMB Brushless Servomotors series. As an integral component in industrial automation, it converts three-phase power from a drive into controlled torque and velocity for linear or rotary mechanisms. The unit’s frameless electromagnetic design minimizes maintenance and supports high cycling rates demanded by assembly cells, electronic packaging lines, and small gantry stages. It is suited to systems that need compact rotary power and repeatable motion in a small mounting envelope.

Mechanical and electrical dimensions align with the standard NEMA Size 34 frame, so the motor fits equipment designed for a 3.4-inch square package. Under locked-rotor conditions, the winding draws a nominal stall current of 5.4 ARMS, so drive sizing must account for that steady-state value. At the rated supply of 240 VAC, the motor operates within the continuous thermal capacity of the stator without forced cooling. Rotor position feedback for electronic commutation is provided by an integral Hall sensor, allowing six-step control or startup alignment for higher-resolution encoders mounted on the load side. Power and signal conductors exit the housing as flying leads, which simplifies routing through cable tracks and eliminates the need for an on-motor junction box.

The wiring harness terminates with industry-standard AMP connectors, so plug-in connections can be made without field crimping. The rotor uses a flat shaft end to accept setscrew couplings and help prevent slippage during high-torque reversals. For environments prone to oil mist or fine dust, a customizable shaft seal can be specified to reduce bearing contamination and help maintain lubricant integrity. The magnetic circuit uses a stack length multiple of 2, giving this model a medium torque constant within the series while preserving moderate inertia for responsive acceleration.
