Product Description:

The MAC112C-2-KD-2-C/130-A-G/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is designed for analog drive topologies that control velocity and position in automated lines. By converting regulated electrical input into commanded shaft rotation, the unit supports coordinated motion on equipment such as printing presses, palletizers, and metal-cutting feed drives.

This motor is built on frame size code 112, a housing diameter that balances torque capacity with installation space in medium-power axes. Heat is removed through axial surface cooling; an external fan directs air along the stator jacket so continuous torque can be maintained without thermal derating. Under rated conditions, the shaft speed reaches 1500 rpm, allowing simple 1:1 gearing to standard machinery that expects 1500 rpm mechanical input. The auxiliary blower operates from an independent supply of AC 115 V, letting the cooling circuit remain active during low-speed or standstill operation where self-ventilation would be inadequate.

Mechanical alignment to gearboxes or couplings is aided by a centering seat of 130 mm, helping maintain concentricity between the motor shaft and the driven load. The stator stack has length code C, giving the motor the active iron length used in this frame size. For speed feedback, the motor carries a tacho generator that produces 3 V/1000 rpm; this analog signal supplies the drive with real-time velocity information at a sensitivity compatible with most MAC controllers. Power conductors are routed through a connector on side A, simplifying cable runs in cabinets where the drive is mounted to the left of the motor. Electrical characteristics follow winding set KD, which is used in applications that require moderate current and a standard DC bus voltage while keeping motor inertia at a practical level.
