Product Description:

The MAC112A-0-ZD-2-C/130-A-0/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, the unit converts controller voltage commands into regulated rotary motion that positions tool heads, conveyors, or indexing tables. Its standardized frame and connector layout support integration into automated machinery while keeping installation straightforward in compact motion systems.

The motor body is machined with a centering pilot of 130 mm, allowing precise concentric alignment to gearboxes or mounting flanges and helping keep runout within normal operating limits. Heat generated in the windings is removed by natural convection, so ambient airflow must be maintained and no external blower is required. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, which suits applications that prioritize steady torque at moderate speed. A permanent-magnet tacho generator provides a feedback voltage of 3 V/1000 rpm, and this proportional signal feeds analog regulators that modulate phase current in real time. The motor uses the ZD winding, which provides the electrical balance intended for medium-speed, high-torque operation.

The motor uses size code 112, and length code A indicates the shortest magnetic stack in this frame. Power conductors are routed through a keyed plug with a connector on side A, which simplifies cable routing when the motor is mounted against vertical panels or within narrow machine sections. The motor has no blocking brake, so holding torque during power-off conditions must be supplied by the drive or by an external locking device. Standard tachofeedback with normal tacho quality reports speed for the control loop, allowing the motor to operate without a digital encoder in analog servo applications.
