Product Description:

The PMB32D-00116-02 is a brushless servomotor manufactured by Pacific Scientific and assigned to the PMB Brushless Servomotors series. The unit is intended for industrial automation where closed-loop speed and position control are required. It supplies mechanical power to indexing tables, pick-and-place arms, and other motion axes that need repeatable response during frequent start-stop operation. The motor is built for applications that rely on controlled acceleration, steady running speed, and accurate stopping at commanded positions.

Mechanical framing follows NEMA Size 34, giving a 3.4-inch face dimension that matches standardized gearheads and mounting brackets. Power is supplied through flying leads with AMP connectors, a pre-terminated harness that shortens installation time and eliminates panel adapters. Rotor position feedback comes from a 4096 ppr incremental encoder. Its commutation tracks are read by a digital encoder with commutation sensor set, so the drive can produce sinusoidal phase currents without manual phasing. Under locked-rotor conditions at 240 VAC, the winding draws a 5.4 ARMS nominal stall current, a value used in drive sizing to confirm that the amplifier can deliver continuous torque without exceeding thermal limits.

A PTC thermistor is embedded in the stator to signal the controller when winding temperature approaches its safe limit. This arrangement helps protect the insulation system during demanding duty cycles and repeated load changes in industrial service. The shaft is machined with a flat, so low-profile couplings can transmit torque without a key and still maintain angular orientation during assembly. To raise continuous torque beyond the baseline frame rating, the motor uses a stack length multiple of 2, increasing active iron and copper while keeping the external footprint unchanged. Its designation as a PMB Series Brushless Servomotor links the model to compatible drives with matching electrical constants for consistent motor control behavior.
