Product Description:

The MAC112C-0-HD-3-C/130-B-1/S05 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This model is intended for analog drives, where it converts command voltages into precise rotary motion for machine tools, packaging machinery, and general automation axes. By delivering controlled torque and speed through closed-loop operation, the motor maintains repeatable positioning accuracy in installations that rely on analog reference signals. Its housing and mechanical interface follow the established MAC platform, allowing installation in machines that use the same frame.

The motor uses frame size 112, providing a mounting footprint common to mid-range machines in the series, while the length designation C increases active stack height for higher continuous output. Accurate flange alignment is assisted by a centering diameter of 130 mm. Under rated excitation, the rotor reaches 2000 rpm, matching analog amplifier characteristics used in legacy control cabinets. Winding code HD indicates the resistance and inductance values expected by the drive electronics. Three-phase supply conductors terminate in a single connector on side B of the stator housing, simplifying cable routing when the motor is mounted inside a machine frame.

A standard blocking brake is integrated to prevent back-driving and can hold up to 45 Nm when power is removed. Speed feedback is provided by tacho feedback with a second shaft end, which supports velocity monitoring and the attachment of external encoders or couplings. The tacho generator delivers 3 V/1000 rpm, supplying the analog drive with a proportional voltage for closed-loop speed regulation. Heat is dissipated by natural convection, so unobstructed airflow around the ribbed stator surface is required when the unit operates inside enclosures.
