Product Description:

The MAC090C-0-KD-3-C/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Intended for analog drive systems, it converts controlled current into rotational movement for indexers, feed axes, and pick-and-place mechanisms found across general industrial automation. Its electromechanical design combines a permanent-magnet rotor with stator windings matched to classic analog regulators, giving predictable torque response over the linear control range. This operating style suits motion tasks that depend on smooth speed control and repeatable positioning through frequent start and stop cycles.

It delivers a nominal speed of 1500 rpm, which is the shaft velocity under rated voltage and continuous torque. The mounting interface is fixed by a centering diameter of 110 mm, allowing accurate alignment of the stator housing in machine frames and helping prevent radial runout. Heat produced in the windings is removed through natural convection; no external blower or liquid circuit is required, so cabinet airflow planning stays simple. A built-in tachogenerator supplies a feedback signal of 3 V/1000 rpm, which the analog drive electronics use for closed-loop speed regulation. That signal is delivered with standard tacho quality, helping maintain linearity so velocity errors remain within permitted tolerances during continuous duty.

For applications that need emergency holding torque, the motor is supplied without a blocking brake, so static load retention must be handled by external mechanics or sustained drive current. The rear construction includes tacho feedback and a second shaft end, which permits an auxiliary encoder, handwheel, or gearbox to share the rotation without affecting the primary feedback path. The second shaft end can also support linked accessories that need to mirror motor rotation. Power conductors exit via a connector on side A, simplifying cable routing where the drive cabinet is positioned along that face of the machine. The KD winding code identifies the electrical layout used with this motor.
