Product Description:

The MAC090C-0-KD-4-C/110-B-0/WI520LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for integration with analog drive amplifiers, the motor supplies controlled torque for automated axes. It supports accurate speed regulation and repeatable positioning in machinery such as pick-and-place stages, conveyor modules, and other equipment that depends on stable rotary motion.

A centering diameter of 110 mm establishes the pilot fit that aligns the housing with the machine flange, helping the motor seat accurately during installation. The motor reaches a nominal speed of 1500 rpm, allowing moderate operating speed that balances torque production and mechanical life. Heat produced in the stator is carried away by natural convection, so no auxiliary fan or liquid circuit is required and the enclosure can be mounted in compact cabinets. The KD winding provides the coil resistance and inductance matched to analog drives that deliver the proper current gradient. Because there is no blocking brake, holding torque during power-off must be supplied by external mechanics or by the drive's closed-loop current if mains power remains available.

The built-in tacho generator outputs 3 V/1000 rpm, giving the drive electronics an analog velocity signal that scales linearly with shaft speed. Power conductors are routed through a connector on side B, which can simplify cable runs when the motor is installed against a rear panel. Combined velocity monitoring is achieved with tacho feedback. Actual position is derived from an incremental encoder seated in the rear of the frame, allowing the drive to track shaft movement during repeated motion cycles. This separation of speed and position signals gives the external amplifier distinct feedback sources for regulation and motion control during axis reversals and dwell periods.
