Product Description

The SF-B4.0230.030-04.056 is a synchronous servo motor by Bosch Rexroth suited for use with the Servodyn-D Inverter Series. This motor type features high torque density in a compact design delivering high performance and reliability in high accuracy applications. The motor comes with a single-turn absolute value STG encoder. It can also be equipped with an optional multi-turn absolute value MTG encoder. The integrated encoder ensures high accuracy in the evaluation of rotor position and speed. The motor has a frame size of 4 and comes in a robust, low-contamination aluminum frame enhancing reliability even in harsh industrial setups. The motor also has robust ingress protection (IP 67) against moisture and dust ensuring reliability and optimal performance in different environments.

The motor comes equipped with an electronic rating plate that functions in the automatic commissioning of the Servodyn-D inverter. The motor is rated for a nominal speed of 3000 min-1. It has a locked rotor torque of 22 Nm and a locked rotor current of 14 A. The motor has a mass of 25 kg without a holding brake. It is designed to be compact and flexible to adapt to different installation conditions. The motor is brushless and comes equipped with permanently lubricated bearings that ensure minimal maintenance requirements.

The SF-B4.0230.030-04.056 has natural convection cooling which permits use in applications with high cyclic loads. The cooling feature prevents overload damage aided by the built-in temperature sensors in the motor?s windings that help to monitor temperature. On this motor, the output shaft is a shaft with keyway and feather key, without a mating connector. The motor also comes with a holding brake to allow a safe and backlash-free standstill by holding the servo axes in place when the motor is off.
