Product Description

Any businesses looking for the most cost-effective options for solving automation challenges will choose Bosch Rexroth. The company is the expert designer of drive units such as the MAC servo motors used in textile machines and robotics.

The MAC112D-0-HD-4-C/130-B-1/WA611XX/S021 is a brushless servo motor reaching a nominal speed of 1,500 revolutions per minute. It is one of the motor models in the MAC series designed and manufactured by Bosch Rexroth. Its rotor’s permanent magnets are composed of materials that give the motor low inertia and permit its use in dynamic operations. The high degree of operational reliability displayed by this motor is due to its brushless design and the use of lifetime-lubricated bearings. These bearings significantly reduce maintenance requirements and eliminate the downtime experienced with lubrication. They also save costs and present minimal risks of contamination or the use of incorrect lubrication, which can cause engine failure.

Coolants and soluble oil emulsions in the working environment of the machine constitute poor environmental conditions for servo motors. However, the sealed housing of the MAC112D-0-HD-4-C/130-B-1/WA611XX/S021 allows its safe use under such conditions. Its Ingress Protection rating is IP 65, according to DIN 40 050. This means it does not permit the entry of solid extrinsic materials, including dust and multidirectional water jets. The motor power, tachofeedback cables, and encoder cables also meet the demands of this protection category. Its centering diameter is 130mm, while the moment of inertia of its rotor is 230 x 10^-4 kgm². With electronic commutation, the motor can accommodate operations with repeated stress cycles, such as continuous start-stop operations with high repetitive frequencies.
