Product Description

Bosch Rexroth is one of the world’s foremost providers of trusted drive and motion control units. It is the manufacturer of the high-quality MAC AC servo motors used to create rapid-response servo drives with the DSC, TDM, and KDS drive controllers. Their applications include robotics and textile machines.

The MAC112D-1-HD-3-C/130-B-1/S005 is a model of the MAC AC servo motors designed and manufactured by Bosch Rexroth. Its electronic commutation feature makes it suitable for continuous start-stop operations with high repetition rates since it gives the motor a high cyclic load capacity. This means the motor can tolerate continuous stress cycles without a drop in efficiency. It also has an output shaft with keyway per DIN 6885-1 to ensure form-fitting torque transmission and efficient power transfer. The thermo switches present in its stator are useful for monitoring its temperature to prevent irreversible damage caused by heating. Overall, the motor is designed to dissipate heat via a surface cooling mechanism.

Bearings with a nominal service life of 30,000 operating hours are fitted in the MAC112D-1-HD-3-C/130-B-1/S005 and remain lubricated throughout their service life. The bearing assembly permits the application of high radial loads so that pinions and belt pulleys can be directly mounted onto the shaft. These lifetime-lubricated bearings and the motor’s brushless design allow the motor’s maintenance-free operation, enhancing its operational reliability. The encoder in the MAC motor model is tachofeedback and second shaft end to provide greater accuracy and motion control. It also has low inertia, thanks to the use of special magnet materials in the construction of its rotor. This rotor has a moment of inertia of 230 x 10^-4 kgm².
