Product Description:

The PMB33E-00216-03 is a brushless servomotor manufactured by Pacific Scientific within the PMB Brushless Servomotors series. It converts electrical input from a compatible drive into controlled rotary motion for positioning tables, actuated grippers, and other automated machinery. The motor combines power and feedback connections in one package, which helps keep multi-axis installations compact. Because the design is brushless, it avoids commutator wear and supports stable response during repeated starts and stops. This arrangement supports precise speed regulation and accurate torque output during closed-loop operation.

Power enters through flying leads with MS connectors, which provide a plug-in connection while maintaining environmental sealing. At 240 VAC, the winding has a nominal stall current of 7.4 ARMS, which indicates the continuous torque available at zero speed. The housing uses a NEMA Size 34 frame, so it fits common 3.4-inch square mounting patterns used on indexing and conveying equipment. Position feedback comes from a 4096 ppr encoder, giving the drive fine resolution for velocity control and positioning. To protect the motor, it includes a shaft seal and a PTC thermistor, with the seal helping block contamination and the thermistor monitoring temperature rise. This combination supports repeatable motion control without adding separate external sensing parts.

Commutation signals are supplied by a digital encoder with commutation, which removes the need for separate Hall sensors. The rotor uses a shaft flat so pulleys or couplings can be secured without a keyway. Output capability is increased by a stack length multiple of 3, which means the motor uses three lamination sections. The feedback arrangement supports accurate phase alignment between the drive and rotor, helping maintain smooth low-speed operation. This unit is a PMB series brushless servomotor with the specified sensor package aligned for closed-loop control after installation.
