Product Description:

The PMB33E-10200-00 is a brushless servomotor produced by Pacific Scientific and supplied as part of the PMB Brushless Servomotors series. It is intended for industrial automation axes that require accurate torque production and stable speed regulation under digital drive control. The motor’s electromagnetic core and mechanical frame are matched to 240 V amplifiers, making it suitable for indexing tables, carton erectors, and mid-frame robotics where fast, repeatable moves are critical.

This model is built on the NEMA Size 34 mounting footprint, so it fits directly on panels or gearheads already drilled for that frame. The nominal stall current at 240 VAC is limited to 7.4 ARMS, allowing drive sizing and cabling to remain within standard 10 A continuous ratings. Power and feedback conductors exit the housing through flying leads with MS connectors, which simplifies routing through drag chains while maintaining secure locking at the mating ends. Rotor position is reported by a resolver, which provides absolute electrical angle information and tolerates high temperatures and vibration better than optical encoders. A round smooth shaft is provided, allowing couplings or pulleys to be press-fit or clamped without keyways and helping reduce concentricity error in high-speed assemblies.

The motor follows the standard motor configuration, so windings, insulation, and bearings match the baseline factory build without custom deviations. It is described as a PMB Series brushless servomotor in legacy Pacific Scientific drive documentation and application libraries. Magnetic flux density uses a stack length multiple of 3, which increases the active iron without extending the frame diameter and supports higher continuous torque per unit length. The winding, connector, and mechanical interfaces remain consistent across standard units of this model.
