MAC112D-0-ED-2-C/130-B-0

The Bosch Rexroth Indramat MAC112D-0-ED-2-C/130-B-0 is a permanent magnet synchronous servo motor in the MAC AC Servo Motors series designed for high-precision industrial motion control. It features a brushless design with electronic commutation and grease-lubricated ball bearings, ensuring maintenance-free operation in harsh environments. With a nominal speed of 3000 min⁻¹ and a continuous torque rating at standstill, this device delivers repeatable performance in servo applications. The motor’s robust housing and IP65 protection class make it suitable for dusty or wet conditions commonly found on factory floors. Its lightweight yet rigid construction supports dynamic response and long service life.

Detailed technical specifications define the MAC112D-0-ED-2-C/130-B-0’s capabilities. The motor operates at a continuous current at standstill of 63 A to produce a continuous torque at standstill of 35 Nm. The torque constant at 20 °C is 0.620 Nm/A, while the windings resistance at 20 °C measures 0.070 Ω. The winding inductance of 1.3 mH balances electrical responsiveness with current stability. A thermal time constant of 120 min enables predictable thermal management under cyclic loads. The servo motor has a mass of 59 kg, dimensions conforming to a motor size of 112 and motor length coded D, and dissipates heat via natural convection without auxiliary cooling.

Operational features emphasize reliability and real-world performance. The MAC112D-0-ED-2-C/130-B-0 maintains smooth operation at its nominal speed of 3000 min⁻¹ through optimized winding geometry and a high-strength permanent magnet rotor. A built-in thermo switch monitors winding temperature to prevent overload, while the brushless construction eliminates commutator wear. The design supports a maximum permissible ambient temperature range from 0 to 45 °C and installation at altitudes up to 1000 m above sea level. Its natural convection cooling sustains continuous operation without external fans, and the IP65 housing seals out contaminants.

System integration is streamlined through compatibility with Bosch Rexroth Indramat servo drives and controllers, enabling real-time tuning and position feedback loops. The standard face mounting and connection interfaces adhere to industry norms, reducing design and installation time. Target applications include CNC machine tools, packaging machinery, assembly robots, and automated production lines where precision, robustness, and low maintenance are critical. The MAC112D-0-ED-2-C/130-B-0 is engineered for seamless incorporation into modern motion control architectures.
