Product Description:

Bosch Rexroth Indramat manufactures the MAC112B-0-LD-2-C/130-A-0/S05 servo motor for the MAC AC Servo Motors series. Classified as a motor for analog drives, it is used where closed-loop controllers need dependable rotational output. In automated cells, the device supplies controlled torque and speed for gantries, packaging axes, and general motion tasks, linking the drive electronics to mechanical loads through a flange that matches the machine frame. Its design supports direct installation and steady feedback exchange, making it suitable for positioning and speed-controlled duty in general industrial equipment.

Mechanical alignment starts with a centering pilot of 130 mm, which helps seat the motor accurately on a gearbox or machine plate. Heat is removed solely by natural convection, so installation must leave clearance for rising air around the housing. Rotor position and speed are reported through integrated tacho feedback, which lets the analog drive regulate current in real time and react to load changes during operation. Under rated conditions, the shaft reaches 2000 rpm, a speed suited to general servo applications in this frame length. The three-phase power leads emerge through a connector on side A, which helps keep cable routing orderly around the motor body.

The winding set identified by LD is matched to the electrical characteristics used for this motor family. Combined with the frame's size 112 stator, it supports the expected back EMF, and the tacho generator produces 3 V/1000 rpm for the drive's speed signal. Because the motor is supplied without a blocking brake, holding torque during power-off must be provided by external mechanics or by the drive when the application allows it. This arrangement is common on axes that do not need an integrated holding function. The motor is intended for applications that rely on controlled rotation rather than brake-assisted load retention.
