Product Description:
PMB33C-20201-03 is a brushless servo motor from Pacific Scientific Corporation, a subdivision of Kollmorgen. The motor series is PMB, which are brushless motors with IP40 protection class designed for self-cooling. PMB motors are available in 48 Volts DC and 240 Volts AC versions. They can be used with servo drives from the PCx3, PC8x2 and other product lines. Multiple options are available for motor shaft design, feedback device, and power/feedback connections. Customization options are also available for order. PMB33C-20201-03 is a motor with two installed customization options, including a PTC thermistor and a shaft seal. The thermistor is used to monitor the motor winding temperature, and provides protection from overload damage. The shaft seal provided added ingress protection for the shaft and motor bearings. Feedback sensor on this motor is a Hall device.
Frame size of the PMB33C-20201-03 motor is NEMA 34 and its magnet stack length is 3. When used with a PC8x2 or SC9x2/SCE9x2 series servo drive, the motor’s peak stall torque is 9.7 Nm, the continuous stall torque is 5 Nm, the speed rating is 1300 RPM and the continuous stall current is 2.7 Amps. When used with a PC8x3 or SC9x3 series servo drive, the motor’s peak stall torque is 15.9 Nm, the continuous stall torque is 5.4 Nm, the speed rating is 950 RPM and the continuous stall current is 2.9 Amps. The no-load motor speed with all servo drives is 1900 RPM. Weight of the motor unit is 27.2 kilograms. The main shaft on the unit includes square key. Flying leads with MS-type connectors are available for power and feedback connections. Typical industrial applications for PMB motors include semiconductor manufacturing and material handling.
