Product Description:

The MAC112C-0-HD-3-C/180-B-1/S053 is a servo motor built by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It interfaces with analog drive amplifiers to convert commanded currents into controlled mechanical rotation for positioning and velocity tasks in automated lines, presses, and material-handling axes. Its AC servo design supports stable speed control and repeatable motion in equipment that depends on accurate axis response.

A centering diameter of 180 mm aligns the size 112 housing on mounting surfaces, while frame length C provides the center-to-end dimension for coupling layout. At its rated supply, the rotor reaches 2000 rpm, a speed suited to moderate-inertia loads. The integrated blocking brake is supplied as standard and can hold shafts with up to 45 Nm of static torque during power-off conditions. Heat is removed only through natural convection, so airflow around the enclosure must remain unobstructed. The winding code HD corresponds to the resistance, inductance, and current values used by the paired analog drive. This arrangement supports installations that need consistent torque production without external cooling hardware.

The rear face carries tacho feedback and a second shaft end, allowing tachometer voltage monitoring and mechanical coupling of auxiliary devices. The tacho generator produces 3 V/1000 rpm, which analog controllers use for proportional speed feedback during routine motion tasks. Power conductors enter through a connector on side B, helping with cable routing when the motor is installed in tight machine frames. The unit is built as a motor for analog drives, so it matches control systems that regulate current continuously rather than through digitally sampled pulses. The second shaft end also provides flexibility when an external encoder or accessory must be mounted at the rear of the motor.
