Product Description:

Bosch Rexroth Indramat’s MAC112A-0-VD-2-C/130-A-0/S05 belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives. In automated lines, this unit converts drive commands from legacy analog amplifiers into controlled mechanical rotation for positioning tables, presses, or material-handling axes. The frame integrates the rotor, stator, and tachogenerator so that speed is measured internally, allowing closed-loop regulation without external sensors. That makes the motor suitable for retrofit machines that still use original analog motion electronics. Its electromechanical interface and passive cooling simplify integration into existing machine envelopes.

The winding code VD identifies the motor’s electrical constants, matching coil resistance and inductance to standard Indramat analog controllers. A centering diameter of 130 mm aligns the flange precisely with gearboxes or mounting plates, which helps reduce radial runout. Heat is removed by natural convection, so no external blower or liquid circuit is required and the motor remains quiet during operation. Under rated conditions, the shaft reaches 2000 rpm, a speed suitable for mid-torque servo axes. The internal tachogenerator supplies 3 V/1000 rpm, giving the controller a linear voltage feedback signal for velocity control without an added external speed sensor.

Power enters through a connector on side A, keeping cables away from adjacent machinery and easing service access. Because no blocking brake is fitted, the axis must rely on external clamping or drive torque to hold position at power-off. The housing uses length code A with motor size 112, which keeps the stack depth compact while accommodating the active lamination package. Cable routing on side A can also help when neighboring components limit access around the rear of the axis. This layout works well where replacement motors must fit established mounting space and operate with existing analog servo hardware.
