Product Description:

The SG-A2.027.049-03.000 is a Synchronous servo motor that has been developed by Bosch Rexroth Indramat. Servo motors manufactured by Bosch Rexroth Indramat are recognized for their dependability and their widespread use in industrial automation and machine applications.

The continuous torque of 6.3 Nm is produced by the SG-A2.027.049-03.000 synchronous servo motor, which operates at a rated current of 1.8 A and a supply voltage of 310 V. With a speed of 4700 revolutions per minute, the motor is designed for an S1 duty cycle, which enables uninterrupted operation. The extended life and thermal stability are guaranteed by the insulation class F. The motor boasts an IP65 protection classification, which guarantees resistance to water and dust infiltration. The integration of the resolver feedback servo motor allows for exact position detection, which is critical for closed-loop control. The winding temperature is constantly monitored by the motor, which is equipped with a KTY or thermistor temperature sensor. The SG motors are three-phase motors that work with servo actuators in industrial automation applications. The temperature sensor protects the motor from overheating and keeps it operating within acceptable thermal limits. The motor's IP65 protection certification allows it to be utilized in situations where dust and water may be discharged. Insulation class F increases the motor's operational life by withstanding high operating temperatures.

The 905CH motor type is used in the SG-A2.027.049-03.000 synchronous servo motor to ensure consistent and trustworthy performance. Accurate speed and position control are important for automated processes, and the resolver feedback device helps the motor maintain these settings. Because of such features, this motor can provide the exact motion control and consistent torque required for even the most difficult automation applications. A resolver feedback device is used to assure precise motion control via robust feedback performance.
