Product Description

Bosch Rexroth’s MAC motors are permanent-magnet excited servo motors combined with the TDM, KDS and DSC drive controllers to form rapid-response servo drives. These products are used in machine tools, printing presses, and robotics.

The MAC090C-0-GD-4-C/110-A-2/WA604XX/S028 is a servo motor model in Bosch Rexroth’s MAC series. It is equipped with a heavy-duty blocking brake of 14Nm torque for the backlash-free holding of the servo axes when the machine is powered off. This blocking brake uses the closed-circuit principle, ensuring the motor’s energy-efficient operation. The MAC model also features tacho feedback with a mounted encoder for precise position detection and evaluation. Its housing is designed to protect it from dust ingress and water jets sprayed at it from different directions. Based on the DIN 40 050 guidelines, this housing’s Ingress Protection rating is IP 65. It allows the motor’s safe use under adverse environmental conditions, such as the effects of coolants and soluble oil emulsions.

Several product advantages are associated with the compact build of the MAC090C-0-GD-4-C/110-A-2/WA604XX/S028. These include its high power-to-weight ratio and simplified installation. The motor can be installed in any orientation and uses ready-made cables that eliminate additional installation work. With its brushless design and lifetime-lubricated bearings, users can operate the motor maintenance-free. Its bearing assembly also makes the application of high radial loads possible. This permits the direct mounting of pinions and belt pulleys onto the shaft. The nominal speed of this model is 3,000 revolutions per minute, while its rotor’s moment of inertia is 53 x 10^-4 kgm². Unique materials are used in the construction of this rotor to give the motor a low inertia.
