Product Description:

The PMB33C-10100-03 is a brushless servomotor built by Pacific Scientific in the PMB Brushless Servomotors series. Designed for medium-frame motion axes, the unit uses permanent magnets and electronic commutation so a servo drive can regulate speed, torque, and position under closed-loop control. Typical roles include indexing tables and pick-and-place actuators where compact size and stable stall torque support accurate, repeatable motion. This motor is suited to automated equipment that requires responsive acceleration, controlled stopping, and consistent performance during repeated production cycles.

The motor body follows the NEMA Size 34 mounting standard, providing flange and bolt dimensions that match common gearheads and linear stages. Power is delivered through flying leads with AMP connectors, a wiring style that supports straightforward connection while keeping the windings sealed. At a bus voltage of 240 Vac, the winding has a nominal stall current of 3.8 ARMS, giving the drive a clear current level for torque-producing operation. Rotor position is reported by a resolver, allowing analog angle feedback that remains reliable in high-temperature or high-vibration environments. This feedback format supports stable control response in systems that use resolver-to-digital conversion inside the drive or control hardware.

A factory-installed option adds a shaft seal and PTC thermistor, so the housing has added protection against oil ingress while the temperature sensor helps protect the windings from overheating. The output uses a round shaft, which simplifies connection to clamp-style couplings when a keyed interface is not required. Internal laminations use a stack length multiple of 3, increasing active magnetic length without changing the frame diameter. The model is identified as a PMB Series Brushless Servomotor, placing it within the PMB product line. These features make the motor suitable for compact servo axes that need dependable thermal monitoring, sealed shaft support, and straightforward mechanical integration.
