Product Description:

The MAC090C-0-KD-4-C/110-B-0/AM164SG is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, the motor converts electrical input from a matched servo amplifier into regulated mechanical rotation for machine tools, indexing stations, and automated conveyors that must maintain repeatable motion profiles. Its mechanical interface and thermal layout support direct cabinet or frame mounting in standard industrial environments while keeping speed and position loops stable under continuous duty in automated equipment.

The stator uses winding code KD, which sets the phase resistance and back EMF so the controller can meet current limits without saturation. Under rated voltage, the shaft reaches a nominal speed of 1500 rpm, giving a balanced operating point for applications that need both low-speed torque and moderate top speed. A centering shoulder of 110 mm aligns the flange accurately with adjoining gearboxes or machine frames. Heat is removed by natural convection, eliminating the need for external blowers. For primary position feedback, the motor carries an absolute encoder, allowing the controller to read a valid position immediately after power-up and eliminating homing cycles.

The motor has no blocking brake, so static holding torque must be provided by the drive or an external clamp when power is off. Power conductors exit through a connector on side B, keeping cables on the non-drive end of the machine and simplifying routing in enclosed assemblies. The embedded tachogenerator delivers 3 V/1000 rpm as an analog speed signal, and the motor is supplied with tacho feedback to match different controller interfaces. Tacho accuracy is classified as standard, providing sufficient linearity for general-purpose speed regulation.
