Product Description:

The PMB33F-10214-01 is a brushless servo motor manufactured by Pacific Scientific and supplied within the PMB Brushless Servomotors series. Designed for closed-loop motion axes, it converts electrical energy into rotary torque for packaging, assembly, and material-handling machinery in industrial automation. Its laminated stator core and high-energy magnets give it the dynamic performance required for rapid indexing, while an integrated feedback device lets a drive regulate position, velocity, and torque over the full speed range. The model supports standard 240 Vac bus voltages and bolts directly to industry-standard mounts.

The motor frame is classified as NEMA Size 34, giving a 3.4-inch square face that fits common gearheads. At a DC bus derived from 240 Vac, the phase windings sustain a nominal stall current of 11.0 ARMS, letting the drive hold static loads without demagnetizing the rotor. Rotor position is reported by a 2048 ppr optical encoder whose resolution matches high-bandwidth drives. That device is a digital encoder with commutation, so it supplies both incremental counts and commutation signals. Power, feedback, and ground conductors exit through flying leads with MS connectors, allowing straightforward cable connection.

A factory-installed shaft seal blocks oil and coolant from entering the front bearing when the shaft is exposed to washdown spray. The stainless-steel output uses a round profile, enabling clamp or collet couplings instead of keyed hubs. Torque capability is influenced by the stator stack configuration, and the length is set to a multiple of 3, which increases continuous torque compared to single-stack variants without changing the mounting footprint. The unit is identified as a PMB Series Brushless Servomotor and is intended for use with compatible servo drives.
