Product Description:

The PMB33C-10114-00 is a brushless servomotor manufactured by Pacific Scientific and assigned to the PMB Brushless Servomotors series. It supplies closed-loop torque and velocity control for automated axes, enabling coordinated moves in packaging lines, material-handling gantries, and electronic assembly stations. When paired with a compatible drive, the motor's embedded feedback and three-phase windings translate command signals into repeatable rotary motion that supports high cycle rates and accurate positioning.

This model follows the dimensional envelope of a NEMA size 34 frame, which simplifies mounting because the pilot diameter and bolt circle match widely used brackets and gearboxes. At 240 VAC, the stator can sustain a nominal stall current of 3.8 ARMS, indicating the continuous phase current the amplifier must furnish to hold maximum rated torque without overheating. Rotor position is resolved by a 2048 ppr incremental encoder, giving 8192 quadrature counts per revolution when four-edge decoding is used, and this resolution supports sub-degree position loops. Commutation and velocity feedback come from a digital encoder with commutation, eliminating Hall sensors and letting the drive align phase currents precisely at startup. Power and feedback leave the housing through flying leads with AMP connectors, so field wiring can be completed quickly without crimping new terminations.

The mechanical interface uses a round shaft, allowing flexible coupling choices such as clamp hubs or keyed bushings when torque must be transmitted to pulleys or gearheads. Three lamination stacks are bonded in the stator, represented by the stack length multiple of 3. This adds active iron depth for higher continuous torque than shorter builds of the same frame size. The unit ships as a standard motor, meaning no custom windings or seals alter its electrical or dimensional data. Its published ratings can be used directly during system sizing.
