Product Description:

The SG-A1.006.072-03.000 is a brushless servo motor built by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It is intended for precision feed axes and spindle drives where compact dimensions and a quick torque response are required in industrial automation cells. A small integrated holding brake keeps the load in position when power is removed. The resolver supplies rotor angle feedback so the drive controller can establish synchronous commutation without a separate homing procedure.

The motor has a nominal speed of 8800 rpm, allowing high surface velocities on directly coupled ball screws or belt pulleys. A square mounting interface with a 70 mm flange follows Accuracy N tolerances, supporting repeatable alignment across multiple machines. The enclosure is sealed to IP 65, protecting the stator assembly against dust and low-pressure water jets. The small brake operates with a supply of 24 V DC ±10%, which is compatible with common low-voltage control circuits and simplifies connection to cabinet power. The rotor uses permanent magnets made from SmCo, a samarium-cobalt alloy that retains magnetic strength at elevated temperatures and offers strong resistance to demagnetization.

The permitted ambient temperature range is 0 to 40 °C, while Class F insulation supports winding temperatures up to 155 °C under cyclic loading. The keyed shaft measures 11 mm × 23 mm and follows DIN 6885, allowing it to accept compatible standard couplings without additional machining. The motor supports an IM B5 face-mounted arrangement and the permitted IM V1 or IM V3 vertical mounting orientations. Heat is removed through thermal radiation and natural convection, eliminating the need for forced airflow and reducing the number of auxiliary cooling components. Power is delivered through a mating connector that accepts conductors up to 1.5 mm². The accurate flange and keyed shaft support consistent coupling alignment and help minimize runout during repeatable indexing operations.
