Product Description:

The PMB33E-10216-03 is a brushless servomotor built by Pacific Scientific and supplied within the PMB Brushless Servomotors series. As a permanent-magnet AC unit, it is used on positioning tables, pick-and-place axes, and other closed-loop motion stages where dynamic torque and repeatable velocity are important. Its brushless design supports accurate response during frequent starts, stops, and speed changes, making it suitable for servo systems that rely on continuous feedback correction under changing load conditions.

The frame matches the industry-common NEMA Size 34, so it can mount in many machine layouts without adapter plates. A continuous thermal limit of 7.4 ARMS at 240 VAC indicates the current the windings can sustain at standstill, which helps set drive output requirements and conductor sizing. Position feedback comes from a 4096 ppr incremental encoder, giving fine resolution for each mechanical revolution and allowing precise interpolation by the drive. Motor power and signal conductors exit as flying leads with MS connectors, so the cable ends arrive with sealed terminations already attached. The feedback device is a digital encoder with commutation, which provides both incremental counts and commutation signals from one package. A round shaft works with standard clamp hubs or timing pulleys and avoids the need for a keyway.

The optional package includes a shaft seal and PTC thermistor, helping protect the front bearing area from lubricant ingress while also providing a temperature-sensitive input for the control system. The motor uses a stack length multiple of three, which adds active material compared with shorter stacks of the same diameter and supports higher torque density. The unit is identified as a PMB Series Brushless Servomotor, and its electrical characteristics follow the conventions used across that product line.
