Product Description:

The PMB33C-10200-02 is a brushless servomotor from the PMB Brushless Servomotors series. As a three-phase permanent-magnet unit, it serves as the rotary actuator in automated positioning tables, pick-and-place modules, and similar servo axes where fast response and repeatable accuracy are required. When paired with a compatible digital drive, the motor delivers controlled torque while its built-in feedback keeps commanded and actual motion aligned. This operating style supports repeatable indexing and stable speed control on axes that must start, stop, and reverse frequently.

The motor uses a NEMA Size 34 frame with a 3.38-inch square face, so it fits common servo brackets and gearheads used on compact machines. It can withstand a continuous stall current of 3.8 ARMS when supplied from a 240 VAC bus, and that value sets the continuous current level for static holding or low-speed torque demand. Electrical connection is provided through flying leads with MS connectors, which allow secure cable attachment while maintaining a sealed connection path. Rotor position is detected by a factory-aligned resolver, and mechanical output is transmitted through a round shaft that works with clamp or setscrew hubs. Because the feedback device is a resolver rather than an optical encoder, it tolerates dirt, shock, and vibration well in industrial service.

Thermal protection is provided by a PTC thermistor embedded in the stator winding, so the drive can respond if winding temperature rises too far during operation. This sensor gives the control system a direct indication of winding heat instead of relying only on an estimated temperature model. The electromagnetic section uses a stack length multiple of 3, which means three lamination sections are combined to increase active length and raise torque without changing the mounting footprint. That longer magnetic stack helps the motor deliver more output from the same face size, which is useful when machine space is limited around the axis.
