Product Description:

The MAC112C-0-HD-1-B/130-B-1/I00625/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it supports closed-loop axis control in machining centers, printing lines, and other industrial equipment. The compact 112 frame combines a permanent-magnet rotor with integrated feedback so the connected amplifier can regulate velocity and position with low latency. This arrangement makes the motor suitable for applications that need repeatable motion and steady response during changing load conditions.

The integrated blocking brake provides holding torque, and the brake is rated for 45 Nm to help resist back-driving forces when power is removed. Accurate mechanical alignment is supported by a 130 mm centering diameter that seats the housing in a spigot fit on the machine face. During continuous duty, the rotor reaches a nominal speed of 2000 rpm, giving a balanced combination of torque output and dynamic response. A built-in tacho generator supplies 3 V/1000 rpm, which gives analog velocity loops a proportional voltage signal for speed monitoring. Heat is removed through natural convection, so the motor does not require an external fan assembly.

The axis interface uses incremental encoder feedback, which provides high-resolution position data for fine positioning tasks and repeatable motion control. Three-phase supply conductors connect through a connector on side B, which supports straightforward cable routing at the motor connection point. Frame size 112 uses the mounting bolt circle and shaft dimensions common to the MAC family, while the HD winding matches the electrical characteristics needed by high-current analog drives. The C motor length increases the active stack to raise rated power without changing the basic mounting footprint.
