Product Description:

The R33GEBC-R2-NS-VS-02 servo motor is a rotary actuator designed for demanding automation systems. It offers precision, durability and efficient operation with a NEMA 34 frame and flange mount configuration. The motor provides reliable performance in motion control applications with high torque and stable speed control.

This R33GEBC-R2-NS-VS-02 servo motor from Pacific Scientific has a torque constant of 21 lb-in/A and a back EMF constant of 70 V/KRPM. It can deliver a peak torque of 2.4 Nm and operates at a rated speed of 3700 RPM. The rated current of the motor is 3.9 A while the line to line resistance is 8.8 ohms and inductance is 9.9 mH. This ensures stable operation and effective energy conversion. The motor features sinusoidal commutation and has four pole pairs for smoother torque delivery. The ball bearings are sealed and built to support over 20,000 hours of shaft life that makes it a durable component for continuous duty cycles. It uses a resolver as a feedback device that enables accurate position sensing and closed loop control. The servo motor is designed in accordance with insulation Class F which permits a maximum winding temperature of 155 °C. This classification ensures reliable thermal endurance and continuous duty operation under demanding load and ambient conditions.

The R33GEBC-R2-NS-VS-02 servo motor is convection cooled and uses natural cooling methods which helps reduce maintenance needs. It has an IP65 rated enclosure that provides resistance to dust and water jets for use in harsh environments. The motor has two top mount connectors for power and feedback. This makes installation straightforward. Its flange mounting style ensures easy integration into standard systems. The motor’s smooth round shaft allows for consistent rotational movement.
