Product Description:

The PMB33C-00200-01 brushless servomotor is built by Pacific Scientific and belongs to the PMB Brushless Servomotors series. As a torque-producing rotary actuator, it provides closed-loop position and velocity control for indexing tables, pick-and-place axes, and general-purpose automation cells. In these roles, the motor converts electrical commands from a matched drive into mechanical rotation without brush wear, which helps reduce routine service in continuous-duty machinery. Because commutation is electronic rather than mechanical, it also avoids brush dust inside enclosed motion systems.

This motor uses a NEMA size 34 frame, giving it mounting dimensions compatible with standard 3.4-inch square faceplates used across many servo gear stages. During locked-rotor conditions at 240 VAC, its windings draw 3.8 ARMS of nominal stall current, which the drive must deliver to maintain torque at zero speed. Power and feedback exit through flying leads with MS connectors, allowing quick disconnection while keeping cable routing straightforward in modular equipment. Rotor position is reported by a resolver, so the control loop receives angle information that remains reliable in electrically noisy areas and at elevated operating temperatures. The shaft has a flat section for set-screw style couplings instead of a keyed interface. The motor uses stack length multiple 3, which gives this frame a longer magnetic stack and supports higher continuous torque than shorter versions in the same size.

For applications exposed to coolant spray or airborne particulates, the motor can be supplied with a shaft seal, which helps reduce ingress at the output end and preserve internal bearing grease. That option is useful where the shaft area sits near wet process zones, blown debris, or frequent washdown residue. The motor package remains suitable for compact automated equipment that needs dependable feedback, straightforward cable routing, and low-maintenance operation over repeated cycles. Its general form also suits installations where standard mounting geometry and simple coupling methods are preferred.
