Product Description

Bosch Rexroth is considered a trusted and respected brand in the automation industry, with a strong focus on quality, innovation, and customer satisfaction. Its MAC motors are brushless servo motors with tacho feedback. Their applications include handling equipment, printing presses, and robotics.

The MAC090C-0-GD-4-C/110-B-1/WA610XX is a model of the MAC AC servo motors designed and manufactured by Bosch Rexroth. It operates at a nominal speed of 3,000 revolutions per minute and accommodates a maximum current of 196A. It features bearings that remain lubricated throughout their service life, preventing premature wear and failure of the motor. One of the constituents of its rotor’s permanent magnets is rare-earth materials that provide low inertia. This makes it suitable for highly dynamic applications, as it gives a favorable torque-inertia ratio for such operations. As a motor with a high cyclic load capacity, this MAC motor model supports continuous start-stop operations with high repetition rates. It can withstand repeated stress cycles without failing due to fatigue.

Natural convection, a noiseless and energy-efficient mechanism, is used for heat elimination from the MAC090C-0-GD-4-C/110-B-1/WA610XX. The servo motor is enclosed in a housing painted with a black prime varnish that prevents weathering, yellowing, and chalky buildup. This varnish is also resistant to dilute acids and lyes. Its housing is sealed and IP-65-rated according to DIN 40 050, permitting its use directly within the working area of the machine, even under poor environmental conditions. The servo motor is equipped with a standard blocking brake of 6.5 Nm torque for a backlash-free holding of the servo axes when the machine is powered off. This hold brake works along the closed-circuit principle.
