Product Description

The SF-A4.0091.030-04.056 by Rexroth Bosch Indramat is part of the SF motor series. It is a servo motor that is used to work with the Servodyn-D inverter. It is considered a permanently excited motor as the rotating part (the rotor) contains magnets that create a magnetic field in interaction with the stationary part (the stator) to produce the rotational force required for the operation of the motor. No separate winding for the rotor is used because of the permanent magnets that simplify the construction of the motor.

This motor requires no maintenance because of its brushless design and permanent magnets that enable electronic commutation. When compared to other conventional approaches, electronic commutation helps switch the current faster and offers more accurate control over motor operation. The SF motor utilizes AC input and then rectifies it into a direct current of 670 V. These rectified DC voltages are stored on a DC link and can be utilized to power up the components of the motor. This complex process involves semiconductor devices or diodes. The full length of the motor has installation pockets that offer easier integration and installation with various equipment and types of machinery.

The absolute value encoder type employed is either STG or MTG, which provides exact information on the position of the motor's shaft. The design suffix is A with a frame size of 2. 3000 rpm (rotations per minute) is the nominal speed denoted by the type code 030. The mechanical components of the motor include a feather key for the transmission of torque, a shaft with a keyway, and a holding brake. The version of this motor is 056. All these advanced features make it highly reliable, efficient, and easy to use in various industries.
