Product Description:

The PMB33C-10100-02 is a three-phase brushless servomotor manufactured by Pacific Scientific and sold within the PMB Brushless Servomotors series. The device converts commanded current from a compatible servo drive into controlled shaft torque for axes that require accurate velocity or position control. Typical uses include pick-and-place gantries, carton indexers, and light machine tools, where fast response, low maintenance, and repeatable motion are important during frequent start-stop cycles. Because the motor uses a brushless design, it avoids brush wear and helps maintain consistent performance during extended operation.

Mounting follows the NEMA Size 34 pattern, letting the motor fit standard 3.4-inch square brackets without redrilling. This common frame size works well in compact machine sections and on standardized mounting plates. Rotor position is measured by a resolver, which provides durable sine-cosine feedback that remains reliable under vibration and heat. At stall, the phase demand reaches 3.8 ARMS at the maximum rated supply voltage, so the selected drive and cabling must support that current. Power, feedback, and thermal leads exit as flying leads with AMP connectors, which simplifies connection to mating harnesses. Output torque is delivered through a round shaft, allowing clamp-style or compression couplings without requiring a keyed interface.

Overtemperature shutdown is supported by a PTC thermistor, which produces a sharp resistance increase when the winding temperature rises toward its limit. The thermal signal can be monitored by the drive to help protect the motor during repeated acceleration or prolonged low-speed loading. Torque capability is increased by the electromagnetic package's stack length multiple 3, which adds active material depth while keeping the same front mounting pattern. The current range pairs with drives supplied from 240 VAC, which suits installations that distribute this line voltage directly. It is identified as a PMB Series Brushless Servomotor, indicating use with matched products in the same motor family.
