Product Description

With state-of-the-art automation products in its portfolio, users can rely on Bosch Rexroth to provide impressive functionality for various kinds of automation tasks. The MAC AC servo motors by the manufacturer are used in transfer facilities and machine tools.

The MAC090C-1-GD-3-C/110-A-1/S001 is a Bosch Rexroth MAC motor designed to reach a nominal speed of 3,000 revolutions per minute. It has protective thermo switches integrated into its windings to monitor its temperature and prevent irreversible damage due to thermal overload. These thermo switches also ensure its operation within safe temperature limits and reduce energy losses from overheating. Another protective feature of the MAC motor is the black coat covering its housing, with high resistance to weathering, yellowing, and chalky buildup. The coat also protects it from the effects of dilute acids and lyes. According to the DIN 40 050 standard, the motor’s housing has an Ingress Protection rating of IP 65, as it is touch-proof, dustproof, and impervious to water jets from different directions.

A standard blocking brake with a holding torque of 6.5Nm holds the servo axes of the MAC090C-1-GD-3-C/110-A-1/S001 backlash-free when it is disconnected from power. The motor’s cooling system comprises an axial surface cooling unit that permits extreme loads like continuous start-stop operations with high repetitive frequencies. Its feedback type is tacho feedback, with the standard tacho type for precisely evaluating and detecting its rotor’s position and velocity. This rotor’s moment of inertia is 53 x 10^-4 kgm², and it has permanent magnets made from rare-earth materials. The use of lifetime-lubricated bearings in the MAC motor model enhances its operational reliability by reducing the need for maintenance.
