Product Description:

The PMB32D-00201-00 is an electric servo unit manufactured by Pacific Scientific as part of the PMB Brushless Servomotors series. It generates controlled rotary motion when driven by a matched amplifier and is used for positioning, velocity, and simple tension tasks in automated machinery. By eliminating carbon brushes, the motor reduces wear particles and allows higher operating speeds, which supports continuous-duty use in packaging, pick-and-place, and small gantry axes. Its compact format also suits applications where NEMA-frame motors are preferred because available mounting space is limited.

The frame follows the NEMA size 34 standard, so the mounting pilot, bolt circle, and shaft height match commonly stocked brackets and gearheads. Power is transferred through flying leads with MS connectors, a wiring style that supports quick connection changes on the machine. The feedback and commutation sequence rely on a three-phase Hall sensor set, allowing a low-cost controller to track rotor position without a high-resolution encoder. At 240 VAC, the motor has a stall current rating of 5.4 ARMS, and this value is used for fuse sizing and thermal modeling. This arrangement gives the drive enough information for basic rotor synchronization and stable operation during normal servo control.

The mechanical end of the rotor uses a flat shaft, allowing rigid coupling through set-screw hubs while helping prevent slip under reversing loads. Magnet and winding length correspond to a stack length multiple of 2, which increases the active core depth compared with the base model and raises continuous torque without changing the mounting envelope. This unit ships as a standard motor, so no custom shaft seals or windings are applied. It carries the designation PMB Series Brushless Servomotor. The shaft form is suitable for simple hub-style connections used in compact motion assemblies.
