Product Description:

The MAC112D-0-ED-4-C7130-A-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts drive current into controlled rotary motion for positioning tables, gantry axes, and similar equipment in industrial automation. The frame code 112 and length designation D place the unit in the mid-torque segment of the MAC family, while a standard blocking brake keeps loads secure whenever the drive is disabled. Its configuration supports machines that need repeatable motion with stable speed regulation and dependable holding at standstill.

The motor delivers a holding force of 45 Nm through its integrated brake, so vertical or suspended loads do not drift after shutdown. A 130 mm centering diameter aligns the housing with precision mounting flanges and helps maintain concentricity between the motor and the driven load. Heat is removed by natural convection, eliminating external blowers and simplifying airflow around the installation. The rotor reaches a nominal speed of 3000 rpm, which matches common servo amplifier operating ranges and allows direct coupling to gearboxes sized for that base speed. For velocity feedback, the built-in tacho generator supplies 3 V/1000 rpm, and this linear signal allows analog controllers to regulate speed by comparing commanded and actual voltage levels.

An auxiliary interface supports incremental or absolute encoder devices, so the motor can be paired with higher-resolution digital feedback when the application requires it. Power enters through a connector on side A, which keeps cabling on the same face as the connection area and helps simplify installation in confined machine spaces. Winding set ED indicates the copper fill and electrical resistance used for this speed-torque profile. The motor also uses standard tacho quality, making it suitable for applications that require consistent speed feedback without auxiliary cooling fans.
