MAC112C-0-ED-4-C/130-B-3/WI522LV/S036

The Bosch Rexroth Indramat MAC112C-0-ED-4-C/130-B-3/WI522LV/S036 from the MAC AC Servo Motors series is a high-precision AC Servo Motor designed for demanding automation tasks. It features a motor size 112 frame with a motor length C profile, delivering a nominal motor speed of 3000 min^-1 for rapid acceleration and smooth rotary motion. The drive windings exhibit a resistance of 0.060 ohm and an inductance of 1.0 mH at 20 °C, enabling fine current control and minimal electrical noise. Natural convection cooling type contributes to a compact design while maintaining thermal stability under continuous operation.

This servo motor offers a continuous current at standstill of 57 A (up to 104 A with peak-rated feeding) and continuous torque at standstill of 24.0 Nm (with a peak of 44.0 Nm when overdriven), making it ideal for applications requiring high holding torque. It can withstand a maximum peak of pulse current at 312 A, ensuring robust performance during transient loads. The built-in thermal time constant of 100 min (75 min under certain conditions) extends winding life by managing heat dissipation efficiently, while the rotor moment of inertia of 170 x 10^-4 Kgm^2 balances dynamic response with smooth load handling. Weighing in at 48 kg, the unit’s mass supports mechanical stability in cabinet-mounted or gantry installations.

Engineered for precision motion control, this MAC112C motor integrates seamlessly into standard automation ecosystems and offers reliable operation under various load profiles. The combination of a high torque constant of 0.470 Nm/A and a three-phase AC architecture enables accurate position and speed regulation without external gearboxes. Its durable construction and well-balanced rotor inertia minimize vibration and acoustic noise, resulting in quieter, more efficient system integration. With its robust specification set and no-fan cooling, this servo motor is an optimal solution for CNC machinery, robotic arms, and indexing tables where space constraints and thermal management are critical.
