Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI532/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, the unit converts commanded armature current into controlled shaft motion for positioning tasks and closed-loop speed control in industrial machinery. Its C-length housing uses the standard MAC mounting pattern and coupling geometry, so it fits equipment arranged for this frame size. That arrangement supports stable operation in presses, packaging lines, and gantry axes that continue to use analog velocity controllers.

Mechanical features include a standard blocking brake able to hold up to 45 Nm, and the brake secures the shaft against back-driving during power-off conditions. The motor mounts into machinery with a centering diameter of 130 mm, which helps maintain accurate axial alignment at the machine interface. Heat is removed by natural convection, so the housing must have free surrounding airflow during operation. Under rated excitation, the rotor reaches 3000 rpm for use with common transmission ratios in machine tools. Winding code ED identifies the copper layout used in this motor length and matches the motor to its stated cooling arrangement.

Electrical connections are routed through a keyed power connector on side A of the stator housing, which keeps the power leads organized at the machine interface. Speed feedback relies on a tacho signal that supplies 3 V/1000 rpm, allowing the analog drive to monitor actual motor speed during closed-loop operation. The stator size of 112 keeps inductance within the range expected by compatible analog drive electronics. An incremental encoder is also included for position feedback, giving the controller a direct pulse-based signal for motion monitoring. The motor is suited to control schemes that separate velocity feedback from pulse-based position feedback.
