Product Description:

The PMB32D-00100-03 is a brushless servomotor produced by Pacific Scientific in the PMB Brushless Servomotors series. It converts commanded current into precise rotary motion for position and velocity loops inside automated machinery. This allows indexers, pick-and-place heads, and light packaging axes to follow tightly controlled motion profiles during repetitive industrial operation. Because the motor is brushless, it avoids brush wear and supports smooth electronic commutation in systems that demand repeatable acceleration and deceleration. That makes it suitable for equipment that runs frequent cycle changes without the maintenance associated with brushed designs.

The housing follows the NEMA Size 34 envelope, so mounting interfaces match common 3.4-inch square motor plates used across North American equipment. On a 240 VAC bus, the coil can sustain a nominal stall current of 5.4 ARMS, allowing the drive to supply continuous torque without thermal overload. The output uses a flat shaft end to simplify torque transfer to pulleys or couplings that rely on setscrews. Power conductors exit as flying leads with AMP connectors, which removes the need for a separate terminal box and supports compact cable routing on moving axes. Rotor position is reported through resolver feedback, and the inductive signal remains stable in electrically noisy environments. This helps the servo amplifier maintain accurate commutation and speed regulation when nearby power cables or switching devices introduce interference.

Factory options include a shaft seal and a PTC thermistor. The shaft seal helps limit the entry of contaminants near the bearing area, while the thermistor gives the servo amplifier a direct temperature signal for protective shutdown. A stack length multiple of 2 gives the motor a longer active iron core without changing the front mounting pattern. The longer magnetic stack increases the active area available for electromagnetic interaction, which supports steady torque production during low-speed holding and short indexing moves. This added axial length can be useful when the axis must remain compact at the mounting face but still handle repeated starts and stops.
