MAC112C-0-HD-4-C/130-A-0/DI520LV/S021

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-0/DI520LV/S021 from the MAC AC Servo Motors series is a high-performance MAC Permanent Magnet Motor featuring a continuous current at standstill of 41 (67) A and a continuous torque at standstill of 27.0 (44.0) Nm. Its nominal motor speed of 2000 min^-1 delivers precise motion control, while the maximum peak of pulse current at 195 A allows for dynamic load handling and short burst demands. With a torque constant at 20 degrees C of 0.730 Nm/A and a windings inductance of 2.5 mH, this motor achieves rapid response and stable torque output. The compact motor size 112 frame and motor length C combine with a centering diameter of 130 mm to ensure exact alignment and minimal vibration transfer.

Industrial reliability is enhanced by a windings resistance at 20 degrees C of 0.150 ohm and a thermal time constant of 100 (75) min, supporting sustained operation even under elevated duty cycles. The rotor moment of inertia at 170 x 10^-4 Kgm^2 contributes to smooth acceleration profiles and reduced overshoot, optimizing performance for servo-controlled machinery. Encased in a housing optimized for natural convection cooling, the MAC112C motor maintains its thermal equilibrium without external fans, lowering maintenance requirements and eliminating auxiliary power draws. Despite delivering robust power, the motor weighs just 48 kg, facilitating integration into space-constrained cabinets.

The absence of a blocking brake simplifies the design and accelerates startup performance by removing mechanical resistance to initial rotation. Ideal for continuous applications such as pumps, blowers, and fans, this servo motor offers maintenance-free operation and consistent torque delivery. Featuring standardized AC motor interfaces and a straightforward analog drive connection, the MAC112C-0-HD-4-C/130-A-0/DI520LV/S021 provides a versatile solution for challenging industrial automation environments.
