Product Description:
The PMB33C-10114-00 is a servo motor designed for precision motion control in industrial applications. It belongs to the PMB group designed by Pacific Scientific. The motor delivers a continuous stall torque of 4.80 Nm for sustained load conditions. The peak stall torque reaches 9.70 Nm for short periods under high-load demand.
The PMB33C-10114-00 servo motor has a voltage constant of 110 volts per thousand RPM. It allows accurate voltage-to-speed correlation. The motor provides a no-load speed of 1900 revolutions per minute for faster shaft rotation when uncoupled from the load. The continuous stall torque requires 2.70 amperes RMS. The peak torque output draws 5.30 A RMS. It has a rated rotational speed of 1300 revolutions per minute under load. The rotor mass moment of inertia is 0.00040 kgm2. The torque sensitivity is 1.79 Nm/A RMS to enable precise torque calculation. The PMB33C-10114-00 servo motor has winding inductance of 27.2 mH to support stable current regulation. The total motor length is 210.3 millimeters. This allows it for machinery with restricted installation space. The unit weight is approximately 6.3 kilograms. It makes secure mounting without overloading support structures. The housing carries an IP40 protection rating to guard the motor against solid objects larger than one millimeter. A shaft seal is included to reduce dust and moisture ingress in the shaft area.
The PMB33C-10114-00 servo motor is built with a NEMA Size 34 flange to ensure standardized installation and interchangeability. The output shaft diameter is 26 millimeters with a smooth finish to ensure precise coupling and minimize wear on mated components. The motor uses double-shielded deep groove ball bearings for extended service life and reduced contamination risk. Lubrication retention is supported by the sealed bearing design. Cooling is achieved through natural convection. This eliminates the need for forced-air ventilation.
