Product Description:

The SG-y.006.072-00.010 is a compact servo motor manufactured by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. This rotary unit converts drive current into controlled mechanical torque for positioning axes, feed drives, and automated stations that require precise velocity and angular regulation. Its responsive operation supports machinery that must execute repeated acceleration, deceleration, and positioning movements while maintaining stable control. The compact housing also allows the motor to fit into equipment with limited installation space without sacrificing the controlled motion expected from an industrial servo system.

The motor housing has an IP 65 protection rating, sealing the internal windings against dust and low-pressure water jets during routine washdowns. Its stator conductors use Class F insulation according to VDE 0530, supporting winding temperatures up to 155 °C before the thermal limit is reached. Magnetic excitation is supplied by permanent magnets made from SmCo, a material with high coercivity that helps the motor retain torque capacity at elevated temperatures. The permissible ambient operating range is 0 to 40 °C, allowing full continuous performance throughout typical industrial operating conditions within that temperature range. Winding heat is dissipated through thermal radiation and natural convection, eliminating the need for an external blower or liquid-cooling circuit. This passive cooling method reduces the number of auxiliary components required around the motor and allows heat to move from the housing into the surrounding air.

Shaft feedback is provided by a resolver for rotor orientation and spindle speed, which sends rotor-angle and velocity information to the drive controller. The controller uses these signals to regulate motor current, synchronize magnetic fields, and correct motion when the connected load changes during operation. As a brushless servo motor, the unit has no commutator contacts or electrical brushes that require periodic replacement. Its maintenance requirements therefore concentrate primarily on the bearings and the condition of the mechanical connection rather than on brush wear. The resolver also provides a durable feedback method for industrial equipment exposed to vibration and temperature changes, while the permanent-magnet design supports smooth torque production across the motor’s operating range.
