Product Description

Using Bosch Rexroth’s products leads to improved productivity and efficiency. The servo motors of the MAC series by this manufacturer are permanent magnet-excited motors with several features to ensure functionality. They are used in robotics, machine tools, and textile machines.

The MAC090C-0-GD-4-C/110-B-1/WI520LV/S014 is a MAC servo motor featuring tacho feedback with a mounted incremental encoder installed per standard mounting. This encoder detects and evaluates both rotor position and velocity, functioning with a high level of precision. It is also built to handle harsh environmental conditions. The servo motor is cooled by the energy-efficient natural convection mechanism, which relies on temperature and density differences between the machine and the ambient air. Its windings and stator housing have thermo switches that monitor the motor’s temperature and protect it from irreversible damage due to thermal overload. It also has a high overload capability due to efficient heat dissipation.

Users can mount the MAC090C-0-GD-4-C/110-B-1/WI520LV/S014 in any orientation. It accommodates the direct mounting of pinions and belt pulleys onto the shaft because the design of its bearing assembly makes the application of high radial loads possible. The bearings in the MAC model do not require additional lubrication and remain lubricated throughout their service life. This reduces the motor’s maintenance requirements and prevents environmental pollution from discarded lubricants. One protective feature of the servo motor is its standard blocking brake of 6.5 Nm torque. It works with the closed-circuit principle, holding the servo axes backlash-free when the machine is powered off. It can reach a nominal speed of 3,000 revolutions per minute and has a rotor moment of inertia of 53 x 10^-4 kgm².
