Product Description:

The PMB33E-00216-01 belongs to the PMB Brushless Servomotors series manufactured by Pacific Scientific. It is a brushless servomotor intended for closed-loop positioning and speed control in automated machinery, where rapid response and repeatable accuracy are critical. By combining an integral encoder with an electronically commutated stator, the motor delivers precise torque while maintaining the low-maintenance operation typical of brushless designs.

The frame is classified as NEMA Size 34, so its mounting footprint matches standard 3.4-inch square flanges commonly used on medium-torque axes. That standard frame size also supports compatibility with brackets, couplings, and related hardware built around common NEMA mounting patterns. At locked rotor, it draws a nominal stall current of 7.4 ARMS when powered from a 240 VAC drive. This current level reflects the motor demand under maximum torque conditions and helps match the motor to a compatible drive capacity. Position feedback is generated by an internal encoder that resolves 4096 ppr, supporting tight servo loops and stable speed regulation. The sensing element is a digital encoder with commutation, meaning the same device supplies both incremental position data and the commutation signals the controller uses to sequence stator phases, which simplifies wiring and synchronization.

Electrical terminations exit the housing as flying leads with MS connectors, allowing quick mate-and-lock connection to military-style plugs in control cabinets. A shaft seal is provided to reduce the ingress of lubricants or cutting fluids into the front bearing cavity. The output shaft has a shaft flat, giving set-screw couplings positive drive without a keyway. A rotor stack length multiple of 3 increases magnetic path volume, which raises continuous torque relative to shorter stacks in the same frame.
