Product Description:

The MAC090C-0-KD-2-C/110-A-0 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. As a motor for analog drives, it converts command voltages from legacy drive amplifiers into controlled shaft motion for positioning or speed regulation in factory machinery. The unit fits applications where velocity feedback is processed in the drive controller while mechanical power is delivered directly to gearboxes, lead screws, or belt stages. This arrangement is well suited to established automation systems that continue to use voltage-command control.

Mechanical fit is based on a 110 mm centering diameter that locates the housing precisely on a machine flange and helps keep radial runout low. The motor can reach a nominal speed of 1500 rpm, matching drive designs that operate at moderate speed while maintaining steady torque. Thermal energy leaves the stator through natural convection, so surface area alone carries away heat without forced airflow. The KD winding code sets the phase resistance and inductance used by the analog amplifier for rated current delivery. For speed feedback inside the controller, the built-in tacho generator outputs 3 V/1000 rpm, providing a proportional voltage signal for closed-loop correction.

The power lead exits through a connector on side A, allowing cable routing parallel to the motor axis when space behind the flange is limited. Rotor velocity is monitored through tacho feedback, so the controller receives a direct speed signal without a separate encoder interface. During power-off conditions, the shaft remains free to turn because the motor is supplied without a blocking brake, so external holding devices are required for vertical loads. The tacho is built to Standard quality, providing repeatable voltage linearity for conventional analog control loops.
