Product Description:

The PMB33E-00201-03 is a brushless servomotor produced by Pacific Scientific as part of the PMB Brushless Servomotors series. Designed for integration with digital drives, the unit delivers responsive torque for pick-and-place gantries, feeder lines, and packaging machines. By using permanent-magnet technology, it supplies continuous rotary motion while allowing the precise velocity and position control required in automated production cells and robotics. This motor format is well suited to applications that need repeatable starts, stops, and directional changes without the wear associated with brushed designs.

Its frame is rated at NEMA Size 34, giving the motor a 3.4-inch square face that fits standard mounting patterns. The winding can draw a nominal stall current of 7.4 ARMS when powered from 240 VAC, so the drive electronics must furnish that steady phase current without exceeding thermal limits. Power exits the housing through flying leads with MS connectors, a layout that supports quick electrical connection while keeping the pigtails flexible for tight bends. Rotor position feedback is provided by an internal Hall sensor, allowing six-step commutation and basic speed detection without an external encoder. A flat shaft end is supplied, simplifying the attachment of clamp-style couplings and helping resist slippage during intermittent reversing loads.

Optional features for this model include a shaft seal and PTC thermistor. The seal helps block airborne contaminants from entering the front bearing, while the thermistor relays winding temperature to the drive for overload supervision. The electromagnetic section uses a stack length multiple of 3, which increases the active iron length and raises continuous torque compared with shorter stacks in the same frame. Delivered as a brushless servomotor, it eliminates brush wear and supports longer operating intervals between service events. The model remains identifiable as a product from Pacific Scientific, and its overall configuration suits motion systems that need compact motor dimensions, stable commutation feedback, and straightforward drive integration.
