Product Description

Bosch Rexroth is a well-established and reputable brand in the automation industry. It is the designer of the reliable AC servo motors of the MAC series. These motors form rapid-response drives with the KDS, TDM, and DSC drive controllers. They are used in machine tools, robotics, and printing presses.

The MAC090C-0-GD-4-C/110-B-1/WA606XX is a servo motor with electronic commutation in the MAC series by Bosch Rexroth. Its nominal speed is 3,000 revolutions per minute, and it functions with a rotor moment of inertia of 53 x 10^-4 kgm². This rotor, composed of permanent magnets made from rare-earth materials, gives the motor a low inertia for reduced power consumption. The servo motor’s bearing assembly design allows the application of high radial loads so that pinions and belt pulleys can be directly mounted onto the shaft. Like other MAC motors, it has a high cyclic load capacity, meaning it permits continuous start-stop operations with high repetition rates.

Cooling is achieved via natural convection in the MAC090C-0-GD-4-C/110-B-1/WA606XX. It works by dissipating the heat generated during the motor’s operation over a temperature gradient. This cooling mechanism is noiseless and environment-friendly, with no maintenance requirements. The servo motor’s lifetime-lubricated bearings also aid its maintenance-free operation since they do not require additional lubrication throughout their service life. Another feature of the motor that contributes to this is its brushless design. It is equipped with thermo switches in its windings and stator housing for temperature monitoring, preventing irreversible damage caused by overheating. With its standard blocking brake of 6.5 Nm torque, user safety is enhanced, as it holds the servo axes backlash-free when it is disconnected from power.
