Product Description:

The PMB33F-00101-01 is a brushless AC servomotor manufactured by Pacific Scientific for the PMB Brushless Servomotors series. In automated machinery, the unit converts commanded power into precise rotary motion, making it suitable for applications that require repeatable positioning and steady speed regulation under varying loads. The motor is intended to work with matching digital drives and feedback electronics so that its characteristics can be used in closed-loop control systems on production lines, packaging equipment, and material-handling axes.

The motor frame corresponds to NEMA Size 34, so its 3.4-inch square face and bolt circle fit standard gearboxes and brackets. During continuous stall at 240 Vac, the windings tolerate 11.0 ARMS, which the servo amplifier must supply while keeping internal temperature within safe limits. Power exits the housing through flying leads with AMP connectors, which allow quick integration without an extra terminal box and keep the overall length compact. Rotor position information is provided by a Hall sensor, giving commutation signals every 60 electrical degrees for drive feedback. A built-in shaft seal helps minimize lubricant loss and blocks airborne contaminants from entering the front bearing cavity when the motor is installed in dusty or oil-laden environments.

Higher torque density is achieved with a stack length multiple of 3, which adds lamination sections while preserving the frame outline. This longer magnetic stack increases active material without changing the mounting face, which is useful where the bracket size is already fixed. The output shaft has a flat, so couplings can be clamped directly without a key and can be aligned with simple hub designs. As a PMB Series Brushless Servomotor, the unit follows the dimensional and electrical arrangement used across this motor line, which helps maintain predictable mounting and drive matching.
