Product Description:

The MAC112C-0-HD-2-C/130-A-2/S018 is manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it is designed to pair with velocity and current controllers that rely on analog command signals rather than fieldbus networks. Within automated cells, the assembly translates those commands into controlled rotary motion for feed axes, material-handling gantries, and machining spindles. This operating role supports repeatable positioning and steady speed regulation in machinery that depends on a direct relationship between commanded current and shaft response.

Operational safety is enhanced by a heavy-duty blocking brake that applies 60 Nm of static torque to prevent shaft movement when power is removed. During motion cycles, the rotor reaches a nominal speed of 2000 rpm, giving analog drive amplifiers a predictable velocity reference for mid-range industrial axes. Heat generated by copper loss is removed through natural convection, so no separate blower or liquid manifold is required. This cooling method keeps the motor suitable for installations that favor simple thermal management and minimal auxiliary hardware. The built-in tacho generator supplies 3 V/1000 rpm, and its output is used as rate feedback so the controller can close the velocity loop without an external encoder.

A centering pilot of 130 mm aligns the stator flange with adjacent machine frames and promotes concentricity between coupled shafts. Power is routed through a connector on side A, keeping the high-energy conductors on the same side as the incoming drive cabinet and helping maintain orderly cable routing. The motor uses frame size 112, and length code C provides a longer stack for increased continuous torque capability. It is also equipped with winding code HD, and the standard tacho quality supports stable voltage linearity during speed regulation.
