Product Description:

The PMB33F-10101-00 is a brushless servomotor built by Pacific Scientific for the PMB Brushless Servomotors series. This brushless servomotor converts controlled electrical input into repeatable torque for automated feed drives, pick-and-place modules, and indexing tables where stable motion response is required. When coupled to a servo amplifier, the motor provides closed-loop rotary actuation, eliminates brush wear, and supports precise speed regulation in industrial automation lines. The brushless design also reduces routine maintenance associated with commutator components and helps the motor maintain consistent performance during frequent start-stop cycles.

The power interface uses flying leads with AMP connectors, allowing direct splicing or plug-in termination inside a cabinet without a mating motor connector shell. Its frame is specified as NEMA Size 34, so the front face and mounting hole pattern match standard 3.4-inch square brackets common on mid-torque servo axes. A built-in Hall sensor supplies commutation signals to the drive, supporting controlled operation at low speed and at zero speed. Under worst-case thermal conditions and 240 Vac excitation, the winding has a nominal stall current of 11.0 ARMS, which helps size the amplifier and power cable for continuous holding load.

The motor has a round shaft, so torque is transferred through external couplings or clamps rather than a keyed interface. It is supplied as a standard motor, meaning no custom winding or housing option is applied to this version. The magnetic stack uses a stack length multiple of 3, which increases the active material compared with shorter motors in the same frame size. Because the shaft is round, the driven load can be aligned with common clamp-style or set-screw couplings used on compact servo axes. The longer stack supports higher continuous torque without changing the flange dimensions.
