The Bosch Rexroth Indramat MAC112C-0-ED-4-C/180-B-2/AM164SG/S055 is a high-performance member of the MAC AC Servo Motors series, engineered for precision and reliability in demanding industrial environments. This MAC Permanent Magnet Motor offers integrated tacho feedback and mounts an incremental or absolute encoder with a rigid blocking brake. Designed and manufactured by Bosch Rexroth Indramat, it delivers robust output through natural convection cooling and features a C-side power connector for simplified installation. The winding type ED supports standard applications while ensuring consistent performance across varying loads and speeds. With a nominal speed of 3000 min^-1 and high power density, this motor excels in automation tasks requiring accurate torque control and minimal maintenance.
The technical specifications of the MAC112C-0-ED-4-C/180-B-2/AM164SG/S055 define its capabilities in precise engineering terms. It sustains a continuous current at standstill of 57 A and provides a continuous torque at standstill of 24.0 Nm, with a maximum peak of pulse current of 312 A for dynamic acceleration profiles. The torque constant at 20°C of 0.470 Nm/A and windings inductance of 1.0 mH work in concert with a windings resistance at 20°C of 0.060 ohm to ensure efficient current-to-torque conversion. The motor’s rotor moment of inertia of 170 x 10^-4 kg·m² balances responsiveness with stability, while the thermal time constant of 100 min supports continuous operation under heat buildup. Weighing 48 kg, this size 112 unit delivers a reliable mass-to-torque ratio.
Operationally, the MAC112C motor’s performance is characterized by precise current control and low maintenance demands. Natural convection cooling eliminates the need for auxiliary chillers, and the integrated blocking brake provides brake torque of 14 Nm to hold loads securely in power-off states. The combination of incremental or absolute encoder feedback and tacho output ensures real-time speed and position monitoring, enabling rapid response in closed-loop control systems. The motor sustains a nominal motor speed of 3000 min^-1 while accommodating brief high-current pulses without thermal overload, thanks to its robust thermal time constant and optimized magnetic design. This resilience under dynamic load changes makes it well suited to continuous duty cycles in automated production lines.
System integration is straightforward via the C-side power connector and standard encoder interfaces, allowing seamless connectivity with most servo drives and motion controllers. The MAC112C-0-ED-4-C/180-B-2/AM164SG/S055 is ideal for CNC machine tools, automotive assembly equipment, packaging machines, and robotics applications that demand high precision, long service life, and minimal downtime. Its combination of advanced feedback options, high torque density, and rugged construction ensures compatibility with modern industrial control architectures while meeting stringent performance requirements.
