Product Description:

The PMB33F-00200-01 brushless servomotor is manufactured by Pacific Scientific as a member of the PMB Brushless Servomotors series. It is intended for precision positioning and speed regulation tasks in automated machinery, where the drive governs electromagnetic torque by monitoring rotor feedback. In closed-loop motion systems, the motor provides rotary output that can track commanded speed changes, positioning moves, and repeatable cycle timing across automated equipment. Because the motor is brushless, commutation is handled electronically by the drive rather than by mechanical brushes, which reduces wear at the rotating interface.

The motor uses a standard NEMA Size 34 frame, so its flange pattern aligns with common 86 mm mounting hardware used on packaging stations and conveyor axes. Power and signal conductors leave the housing as flying leads with MS connectors, which helps simplify wiring where space around the motor is limited. Under worst-case stall at 240 V AC, the winding draws a nominal current of 11.0 ARMS, so the connected drive must support that load without thermal shutdown. Rotor position is returned through a resolver, allowing the controller to determine shaft angle and velocity in electrically noisy environments. For applications exposed to dust or coolant spray, the motor can be ordered with a shaft seal to reduce ingress at the output end.

The output end uses a flat shaft, giving couplings or pulleys a straightforward contact surface for clamping. The motor has a stack length multiple of 3, which increases active magnetic length without changing the external frame size. That arrangement helps raise torque capacity while keeping installation dimensions consistent with the existing mounting envelope. The flat shaft also supports compact hub styles that rely on set screws or clamping elements instead of keyed connections. This layout helps the motor fit servo axes that need predictable acceleration and stable speed control under changing process loads.
