Product Description:

The PMB33C-10100-00 brushless servomotor is built by Pacific Scientific and belongs to the PMB Brushless Servomotors series. As a rotary actuator for industrial automation, it delivers commanded torque and speed to positioning stages, indexing tables, or material-handling axes that rely on closed-loop servo control. By combining a permanent-magnet rotor with electronic commutation, the motor converts drive current into rotation without brushes, which helps reduce maintenance and supports high-duty operation. The brushless design also avoids commutator wear and helps maintain consistent response during frequent start-stop cycles.

A key mechanical characteristic is its NEMA size 34 frame, which sets the bolt circle and face dimensions used on this motor format. Under a 240 V AC bus, the windings can sustain a nominal stall current of 3.8 ARMS, and the stated input level of 240 VAC matches common servo amplifiers in the medium-power range. Rotor position feedback is delivered by a resolver, an analog sensor that outputs sine and cosine signals for precise angular measurement in electrically noisy environments. Power is transmitted through a round shaft, which simplifies coupler selection when torque loads are moderate.

The electromagnetic package uses a stack length multiple of 3, which indicates three stator lamination sections arranged to increase torque while keeping the same motor footprint. Field wiring is provided as flying leads terminated with AMP connectors, allowing direct connection to drive and feedback harnesses without a terminal box. The lead-and-connector arrangement also reduces the need for separate terminal hardware inside compact machine enclosures. This unit is supplied as a standard motor, so its winding, inertia, and sealing arrangement follow the normal PMB configuration. It is suitable for pick-and-place equipment, test stands, and light conveyor drives that require brushless operation and closed-loop control.
