Product Description:

The PMB33E-10101-00 is a brushless servomotor built by Pacific Scientific and assigned to the PMB Brushless Servomotors series. It serves as the torque-generating element on closed-loop positioning axes used in material handling, packaging, and semiconductor tools, where consistent speed regulation and rapid indexing are required. By supplying three-phase current from a matched servo amplifier, the motor produces precise rotation without brush wear, allowing multiple axes to operate with consistent response across an installation while reducing maintenance associated with commutator-based designs.

The frame is classified as NEMA Size 34, a mounting envelope that matches common 86 mm square flanges and supports installation on existing mechanical plates. Rated nominal stall current reaches 7.4 ARMS when operated from 240 VAC drives, so the controller must supply that continuous phase current to hold torque at zero speed. Rotor position feedback is delivered by an integral Hall sensor, and power and feedback conductors exit the housing as flying leads with AMP connectors for direct wiring to terminal blocks. This lead arrangement avoids bulkier housing-mounted connectors and helps keep the motor package compact. The unit is a Standard Motor, indicating that it does not use customer-specific windings or shaft modifications.

The mechanical interface uses a round shaft that accepts clamp or set screw couplings without the alignment constraints of keyed designs. Magnetic stack length is scaled by a multiple of 3, providing higher continuous torque than shorter stacks while retaining the same front-face geometry. The product type is listed as PMB Series Brushless Servomotor, which distinguishes the motor from gearheads and drive units in the same family. This layout supports compact servo installations where mounting space is limited but stable torque output is still required.
