Product Description:
The model PMB33F-00200-00 is a compact brushless servo motor designed by Pacific Scientific for industrial automation. It offers reliable operation with high torque output and smooth speed control.
This PMB33F-00200-00 servo motor provides a torque constant of 0.60 Nm/A and a voltage constant of 0.37 V/rad/sec. The continuous stall current of the motor is rated at 9 A while peak torque requires 27.1 A. The motor features a line to line resistance of 0.96 Ohms and inductance of 2.8 mH. Its thermal resistance is 0.78 °C/W that allows for effective heat dissipation during extended operation. A thermal time constant of 32 minutes ensures gradual heating that supports long term reliability. The viscous damping coefficient of the motor is 0.038 Nm/kRPM which helps reduce mechanical oscillations and contributes to system stability. This motor is optimized for performance at a typical rated speed of 4600 RPM and delivers consistent torque of 4.04 Nm when operated at 240 V AC or 320 V DC bus voltage. These specifications make the motor suitable for high cycle and dynamic positioning applications. Its electrical design allows it to handle high power systems with 240 V AC input and 320 V DC bus operation. This supports applications requiring fast acceleration and deceleration. The motor’s IP40 rated construction provides basic protection against solid particles that is suitable for controlled indoor environments.
The PMB33F-00200-00 servo motor is engineered for continuous duty cycles with consistent performance in demanding environments. The motor is built with internal thermal management that is supported by its low thermal resistance and calculated thermal time constant. This enables sustained operation with reduced risk of overheating. The motor's flat shaft is ideal for direct coupling to loads or mechanical transmission elements.
