MAC112C-0-HD-4-C/130-A-2/DI518LV/S018

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-2/DI518LV/S018 is a high-performance unit in the MAC AC Servo Motors series, offering a standstill torque of 27 Nm and a maximum current draw of 41 Amperes. As a MAC Permanent Magnet Motor, it is designed for demanding industrial robotics applications requiring precise torque at low and high speeds. Its primary function is to deliver smooth, controlled motion in heavy-duty automation, ensuring consistent performance under continuous load.

Operating at a nominal speed of 2000 RPM and a derated speed of 500 RPM, this servo motor excels in tasks such as CNC milling and drilling. It features a tacho feedback system that produces 3 Volts per 1000 RPM, providing real-time speed monitoring and control. The integrated DI518LV incremental encoder generates precise square-wave pulses per increment and detects rotation direction by reading amplitude inversions. Together, these systems guarantee accurate position feedback and dynamic response, enabling high-precision motion control.

Additional features include a heavy-duty blocking brake with a holding torque of 60 Nm to secure the shaft when the motor is de-energized. The brake’s moment of inertia is 32 x 10^-4 kgm², allowing rapid engagement, with a clamping delay of 30 ms and a release delay of 150 ms. The motor relies on natural convection cooling and operates quietly at 70 dB measured at 1 meter, making it suitable for environments sensitive to acoustic emissions. In industrial setups, this servo motor enhances system reliability and efficiency by providing robust braking, precise feedback, and maintenance-free cooling.
