MAC112B-0-GB-3-C/130-A-1

The Bosch Rexroth Indramat MAC112B-0-GB-3-C/130-A-1 from the MAC AC Servo Motors series is a synchronous permanent-magnet excited servo motor designed for high-performance industrial applications. It provides a continuous current at standstill of 41A and develops a continuous torque at standstill of 16.0Nm to support demanding loads. With a nominal speed of 3000rpm and a maximum peak of pulse current of 223A, it excels in rapid acceleration and precise motion control. Engineered according to international standards, this brushless design integrates Tacho feedback and second shaft end for versatile control and monitoring.

The robust enclosure of the MAC112B-0-GB-3-C/130-A-1 meets Protection Category IP65, safeguarding internal components against dust and water ingress while enabling deployment in harsh environments. A thermal time constant of 90min ensures stable temperature management under continuous operation, and the torque constant at 20°C of 0.430Nm/A delivers consistent torque-to-current characteristics. Low winding inductance of 1.2mH minimizes current ripple for smooth torque output at high switching frequencies, and integrated grease-lubricated ball bearings enhance mechanical reliability. At just 35kg mass, this servo motor combines compactness with structural robustness for high-density installations.

Heat generated during operation is dissipated via natural convection, eliminating the need for external cooling blowers and reducing system complexity. A built-in holding brake secures the load when the motor is unpowered, ensuring safe positioning and retention in machine tools, robotics, and material handling applications. This motor’s blend of precision, durability, and ease of integration makes it an ideal choice for demanding automation tasks.
