Product Description

Top-quality products, innovative solutions, and a commitment to sustainability distinguish Bosch Rexroth in the automation industry. The MAC motors by this company are brushless AC servo motors with tacho feedback. They are especially well-suited for applications like packaging machinery, handling equipment, robotics, and textile machines.

The MAC090C-0-KD-4-C/110-B-2/WA612XX/S013 is an electronically commutated MAC AC servo motor designed and manufactured by Bosch Rexroth. Its high cyclic load capacity results from its electronic commutation, allowing operations with repeated stress cycles without failure due to fatigue. This means the MAC model can accommodate continuous start-stop operations with high repetitive frequencies. It also has a low inertia because of the use of rare-earth materials in the permanent magnets of its rotor. The light weight of these rare-earth materials aids the motor’s quick response to changes in load and speed, producing a highly dynamic performance. They also have a low magnetic loss, leading to the generation of less heat during the motor’s operation.

An output shaft with a sealing ring in the MAC090C-0-KD-4-C/110-B-2/WA612XX/S013 aids the transfer of the motor’s motion to the load. Its sealing ring prevents fluids from entering the motor through the shaft. The MAC motor also has a heavy-duty blocking brake with a holding torque of 14Nm for holding the servo axes when the machine is powered off. This holding brake uses the closed-circuit principle. Tacho feedback and a mounted encoder evaluate the rotor’s velocity and position in this servo motor. The tacho type is standard, and the encoder is suitable for varying environmental conditions. Protecting this MAC model from irreversible damage caused by overheating are thermo switches built into its stator windings.
