Product Description:

PMB31D-20201-00 is a compact servo motor from Pacific Scientific Corporation. The motor comes in NEMA size 34 enclosure with IP40 rating. This rating means the motor is not safe from dust or liquid ingress. The motor design is brushless, which means internal electronic circuits perform commutation. The main benefit of this design is higher reliability. Brushless motors require significantly less maintenance than brushed motors. Brushless motors are also safer than brushed motors because no sparking is produced during commutation. The motor winding code is D. Performance of the motor depends on the servo drive that it is used with. When used with PC8x4 series drives, the motor delivers 6.2 Nm peak stall torque, 2.1 Nm stall torque, and 5000 RPM rated speed. When used with SC8x3 series drives, the motor delivers 4.3 Nm peak stall torque, 2.1 Nm stall torque, and 6000 RPM rated speed.

The feedback sensor on the PMB31D-20201-00 motor is a Hall sensor. Other feedback options for PMB motors include encoders and resolvers. Operators can order PMB motors with different connector types including flying leads with amp or MS connectors. PMB31D-20201-00 is motor with MS connectors on flying leads. Shaft options for PMB motors include flat, round, with square key, and Woodruff key. The shaft on this motor includes a square key. Input voltage for the motor is 240 Volts AC. This voltage is supplied by the servo drive. The motor DC bus voltage is 320 Volts. At no-load the motor can sustain 8400 RPM. This servo motor is well-suited to industrial applications requiring efficient performance and precision. Professional handling is a key requirement for ensuring error-free installation and reliable operation in the long term.
