Product Description:

The PMB33E-10201-00 is a brushless servo motor manufactured by Pacific Scientific within the PMB Brushless Servomotors series. As a permanent-magnet unit, it converts drive current into controlled rotary motion for indexing tables, pick-and-place heads, and similar motion axes in industrial automation cells. Its servo design supports accurate speed regulation and repeatable positioning during cyclic machine operation. Because the rotor uses permanent magnets instead of field windings, torque response remains immediate when the amplifier changes current.

The frame follows the NEMA Size 34 standard, so its mounting face and pilot diameter match common brackets and gearheads in that class. A nominal stall current of 7.4 ARMS at 240 VAC indicates the continuous current the drive must supply without exceeding winding temperature limits. Power and feedback wiring exits the housing through flying leads with MS connectors, allowing secure connections while keeping cable routing straightforward. Rotor position feedback is delivered by a three-phase Hall sensor, and these digital signals support stable commutation at low speeds. The motor uses a round shaft, which simplifies coupling to pulleys or flexible couplings because no keyway machining is required. The connectorized lead set also separates the motor from the mating cable assembly, which is useful when the machine layout requires frequent disconnects.

This unit is supplied as a standard motor, so it does not include special windings or added mechanical options. The magnetic circuit uses a stack length multiple of 3, which increases active material in the same frame size and helps raise torque compared with shorter versions. Classified as a PMB Series Brushless Servomotor, it is intended for use with compatible servo amplifiers that provide regulated current and electronic commutation. Published electrical data from Pacific Scientific helps match the motor with suitable drive and protection hardware. This format is commonly used where compact size, predictable thermal behavior, and straightforward electrical interfacing are preferred over custom mechanical features.
