Product Description:

The MAC112C-0-HD-3-C/180-A-0/S003 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drives, where it converts controller commands into precise rotary motion for positioning and speed control in industrial automation. Tacho feedback is available on a second shaft end, allowing the drive to monitor actual motor speed without a separate external encoder. This arrangement supports closed-loop operation in transfer systems, handling equipment, and other machines that rely on stable rotary response.

The housing uses a centering diameter of 180 mm, which helps align the motor accurately with machine flanges or gearbox interfaces. Cooling is provided by natural convection, so the motor dissipates heat without auxiliary fans or liquid circuits when surrounding airflow is adequate. Under rated excitation, the rotor operates at 2000 rpm, a speed suited to medium-inertia applications that require steady motion and responsive control. Power conductors connect through a connector on side A, which keeps cable routing concentrated on one side of the motor. The built-in tacho generator supplies 3 V/1000 rpm, giving the analog drive a proportional speed signal for regulation. The motor is supplied with no blocking brake, so a stationary load must be held by drive torque or by an external mechanical device.

The motor uses winding code HD, which suits MAC drive combinations that operate with higher current at moderate voltage levels. Its frame size is 112, placing it in the stator diameter class associated with this mounting pattern and torque range. The motor length code is C, indicating an extended active stack within the same flange format. A dual-ended shaft supports the integrated tacho arrangement while preserving the compact layout of the motor body. These features keep the unit suitable for analog servo systems that need dependable speed feedback, passive cooling, and a fixed mechanical interface.
