Product Description

The SF-A3.0068.030-10.000 servo motor is manufactured by Indramat Rexroth. The motors from the SF series share some common features, including locked rotor torque, induced sinusoidal EMF, integrated encoders (STG or MTG), and brushless design. The output speed of this brushless motor is 6 times higher than that of the motor, which has brushes. The motor can run for a long time due to the low friction. The motor code 00068 represents the locked rotor torque, which is 6.8 Nm.

The motor's shaft is 40 mm in length and 19 mm in diameter. The size and alignment of the shaft influence the torque of the motor. The purpose of the plug braking resistors' rating is to guarantee that the motors will stop at maximum current in the shortest time. The servo motor determines whether the target angle of rotation has been reached by using encoders (STG & MTG) that identify the angle of rotation and provide feedback control. Positioning control is thus carried out with great accuracy. In a brushless servo motor, a sensor and a circuit board work together to execute the spinning.

The thermistors that are installed in the SF motor are made up of semiconductor material. The thermistor's resistance is temperature-dependent due to the negative temperature coefficient. The motor's basic version is indicated by the last part (000) of the type code, but it can be altered by integrating some advanced features and eliminating some basic components. The components of the SF motor that can be customized according to specific applications are the shaft end, flange precision, plug output direction, and a few other additional elements.
