Product Description:

The PMB33E-10214-01 is a brushless servomotor produced by Pacific Scientific in the PMB Brushless Servomotors series. This unit converts drive current into continuous rotary motion for positioning tasks in automated machinery, conveyor indexing, and pick-and-place axes. It is intended for closed-loop operation, where encoder feedback keeps torque output aligned with commanded motion profiles. That feedback relationship helps the drive correct speed and position errors during acceleration, deceleration, and steady running. Its standardized mounting pattern supports straightforward installation on existing machine brackets, and the design suits medium-inertia loads in packaging and light assembly lines.

The motor uses a NEMA Size 34 frame, so the flange pattern matches standard 3.4-inch square mounts used on mid-range actuators. At full excitation, the winding draws a nominal stall current of 7.4 ARMS when used with 240 VAC drives, which helps determine suitable drive capacity and cable sizing. The feedback system provides 2048 ppr of incremental resolution for accurate commutation and stable velocity control across a wide operating range. Electrical connections are provided as flying leads with MS connectors, which allow external wiring without opening the housing. Rotor position is measured by a digital encoder with commutation, reducing the need for separate commutation sensors and keeping the feedback package compact.

A factory-installed shaft seal helps limit particulate ingress and lubricant migration at the front bearing, which supports stable operation in enclosed machine assemblies. Torque is transmitted through a round shaft, making the motor suitable for clamping hubs, pulleys, and similar coupling styles that do not require a keyed output. The motor uses a stack length multiple of 3, which increases active magnetic length within the frame and supports higher torque density without changing the basic mounting envelope. The sealed front end is useful where airborne debris or light contamination can reach the coupling area during normal machine operation.
