Product Description:

The PMB33E-10214-03 is a brushless servomotor produced by Pacific Scientific within the PMB Brushless Servomotors series. As a direct-coupled rotary actuator, it converts drive current into synchronized torque for positioning axes, pick-and-place heads, and other tightly controlled motion points in industrial automation. By combining a compact electromagnetic stack with electronic feedback, the motor provides closed-loop velocity and position control for machinery that requires repeatable response during continuous duty.

Its frame follows the NEMA Size 34 outline, so mounting holes and shaft height match other 3.4-inch-square devices. Rotor position is monitored by an integral encoder that delivers 2048 ppr of incremental resolution, and this pulse count supports fine angular command updates. Under stall, the windings accept 7.4 ARMS at 240 VAC, which sets an important thermal limit for drive selection. Commutation data is carried in the same feedback package because the sensor is a digital encoder with commutation, eliminating the need for separate Hall devices. Power and signal conductors leave the housing through flying leads with MS connectors, allowing quick connection while maintaining shield continuity.

The customization code includes a shaft seal and PTC thermistor. The seal helps limit lubricant migration, while the thermistor sends temperature information to the drive for overload monitoring. A round shaft simplifies coupling to keyed or clamped hubs when backlash must be minimized. Torque capability is supported by a laminated magnetic core with a stack length multiple of 3, which gives the model more active iron than shorter versions without increasing the mounting face. The motor is suitable for packaging lines, indexing tables, and small gantries that require compact servo mounting and integrated feedback.
