Product Description:

The MAC090C-0-KD-4-C/110-B-0/WI56LV is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive systems where precise torque and speed regulation are required in industrial automation cells. This motor type is often used on equipment that still relies on analog servo architecture rather than networked digital control. By combining an integral tachogenerator with encoder feedback, the motor supplies immediate velocity information to legacy controllers while delivering rotary power to conveyors, indexing tables, and machine axes. In these roles, it converts commanded current into smooth shaft motion for repeatable process control across repetitive duty cycles.

This model uses passive cooling, and the finned housing promotes natural convection so no external blower is necessary. Accurate shaft alignment is supported by a 110 mm centering diameter, which helps the motor seat correctly against machine flanges and gearbox faces. Under rated excitation, the rotor reaches a 1500 rpm nominal speed, matching drives that expect this base operating speed. Power conductors are routed through a connector on side B, which can simplify cable routing when the motor is installed beside adjacent machine sections. This cable exit position can also reduce sharp bends near the mounting face in tighter machine layouts. Speed feedback from the built-in tachogenerator is scaled at 3 V per 1000 rpm, giving analog controllers a linear signal for closed-loop regulation without extra signal conditioning.

Position reference is provided by an incremental encoder with standard mounting, which can be used together with the tachogenerator when tighter motion monitoring is needed. The motor is delivered without a blocking brake, so applications that require holding torque at standstill must rely on an external clamp or maintained drive torque. Coil design follows the KD winding code, which matches the motor to compatible analog amplifiers and their expected electrical characteristics. The encoder arrangement also supports better position tracking during low-speed movement and controlled stopping. This layout suits established servo systems that continue to use analog command structures.
