Product Description

One of Bosch Rexroth’s key strengths is its inclination towards innovation. The brand is the manufacturer of the brushless MAC AC servo motors with tacho feedback. They are used in textile machines, machine tools, handling equipment, and transfer facilities.

The MAC090C-1-GD-2-C/130-B-2/S029 is a compact MAC motor model using lifetime-lubricated bearings with a nominal service life of 30,000 operating hours. These pre-lubricated bearings reduce the need for maintenance and the associated downtime, thereby increasing the motor’s operational reliability. They also reduce the risk of contamination or spillage since additional lubrication is not needed. This MAC model is well-suited for continuous start-stop operations with high repetitive frequencies due to its high cyclic load capacity provided by electronic commutation. It also features an axial surface cooling unit that supports such operations. Thermo switches are built into its windings to monitor its temperature and prevent damage due to overheating.

Tacho feedback comprises the motor feedback system in the MAC090C-1-GD-2-C/130-B-2/S029 for the precise detection and evaluation of its rotor position and velocity. There is a heavy-duty blocking brake with a holding torque of 14Nm in the MAC motor to hold its servo axes backlash-free when the machine is powered off. This safety feature helps to maintain the accuracy of the motor’s position and protects both users and the machine from unexpected motion. A black prime coat covers the housing of the MAC model, protecting it from weathering, yellowing and chalky build-ups. It is also resistant to diluted acids and lyes. This housing meets the standards of the IP 65 protection category according to DIN 40 050. The motor’s nominal speed is 3,000 revolutions per minute.
