Product Description:
The PMB31D-00200-00 is a permanent-magnet brushless servomotor produced by Pacific Scientific and supplied within the PMB Brushless Servomotors series. It provides closed-loop rotary motion for positioning and velocity tasks in automated packaging lines, SMT placement machines, and general assembly cells. By coupling magnetic torque generation with electronic commutation, the unit acts as the electromechanical link between a servo drive and the load, translating commanded current into repeatable shaft movement for precise process control.
The physical form factor of the motor follows the NEMA Size 34 envelope, so mounting dimensions align with standardized 3.4-inch-square flanges often found on mid-frame machinery. During continuous stall at a 240 VAC bus, it draws a nominal peak phase current of 5.4 ARMS; this value guides drive sizing and conductor selection so thermal limits are not exceeded. Rotor position feedback is supplied by a resolver, allowing the controller to maintain commutation and position accuracy under vibration and electrical noise. Output torque is transmitted through a shaft with a flat, giving a straightforward method for set-screw couplings to lock without keys. Power conductors and feedback wiring exit the housing as flying leads with MS connectors, which simplifies cable connection without opening the motor.
Mechanical length is minimized by a single lamination pack, indicated by the stack length multiple of 1, which keeps inertia low for rapid speed changes in demanding servo profiles. No special options are added, and the configuration is identified as a Standard Motor. The device is categorized as a PMB Series Brushless Servomotor within the broader PMB Brushless Servomotors family. This grouping keeps the motor with the corresponding performance and application data used for the PMB line, including electrical and mechanical references for compatible drives.
