Product Description:

The PMB33C-00214-00 is a brushless servomotor produced by Pacific Scientific as part of the PMB Brushless Servomotors series. It converts electrical power from a matched drive into controlled rotary motion for indexing tables, pick-and-place axes, and other positioning tasks inside automated equipment. By combining permanent-magnet construction with electronic commutation, it provides fast response, low maintenance, and repeatable torque in closed-loop motion systems. This motor type is suited to automated axes that require steady acceleration, accurate stopping, and repeatable motion over many operating cycles.

Its frame conforms to the NEMA Size 34 envelope, allowing installation in machine layouts that use the same bolt pattern. The motor has a nominal stall current of 3.8 ARMS at 240 VAC, and this value should be used when matching the drive and power cabling. Position feedback is supplied by a 2048 ppr incremental encoder, giving 8192 counts per revolution with quadrature decoding for precise velocity and position control. The feedback device is a digital encoder with commutation, so no separate Hall sensors are required. Power and signal conductors exit the housing on flying leads with MS connectors, which keeps the motor-side connection compact and supports straightforward integration with existing machine harnesses.

The motor uses a flat shaft end, which provides a broad surface for set screws and helps reduce slip under cyclical acceleration. The electromagnetic stack uses a length multiple of 3, increasing winding volume without changing the mounting face. It is supplied as a standard motor, so no special bearing, seal, or winding arrangement is included. The unit is identified as a PMB Series Brushless Servomotor, which distinguishes it within the product line and aligns it with the intended electrical and mechanical configuration.
