Product Description:

The R43GEBA-R2-NS-NV-00 Servo Motor delivers reliable torque and efficiency across demanding industrial environments. Its optimized electromagnetic structure ensures stable operation and superior power output while maintaining efficiency under continuous loads.

This R43GEBA-R2-NS-NV-00 servo motor features a torque constant of 10.8 lb-in./A and a voltage constant of 128 V/Krpm. It operates with a continuous stall current of 3.5 A and a peak current of 27 A to ensure powerful and sustained performance. This motor's line to line resistance measures 15.1 ohms when hot with an inductance value of 53 mH. This model is capable of delivering a continuous stall torque of 33 lb-in. and a peak torque of 135 lb-in. This motor supports high load applications with precision. The inertia of this motor alone is rated at 0.0018 lb-in.-sec² which allows smooth acceleration and deceleration control. It minimizes energy loss while maintaining motion accuracy with a static friction limit of 0.26 lb-in. The viscous damping coefficient of 0.26 lb-in./Krpm further enhances operational stability. This motor housing is made of heavy duty metal with a protective black coating. This ensures longevity and resistance to wear and tear. It is integrated with cooling fins on the body that helps dissipate heat efficiently.

The Pacific Scientific R43GEBA-R2-NS-NV-00 servo motor is designed for thermal efficiency. It features a thermal resistance of 0.72°C/Watt and a thermal time constant of 19 minutes. The motor Weighs 15 lbs and is built for durability and seamless integration into automation systems. This servo motor features a well machined output shaft with a smooth bearing system that allows for precise rotational movement. This motor is ideal for applications requiring high torque output with precise motion control.
