Product Description:

The MAC090C-0-KD-3-C/110-B-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed as the electromechanical actuator in analog drive systems, it converts amplifier current into controlled rotary motion. This makes it suitable for indexing tables, packaging axes, and other position-dependent tasks on automated production lines. It is intended for machinery that relies on repeatable motion under closed-loop control and consistent response to changing load conditions.

During mounting, the flange aligns to a centering recess of 110 mm, securing concentricity between the motor and driven machine elements. Heat is dissipated by natural convection, eliminating fans and allowing installation without added cooling hardware. The KD stator winding is rated for a nominal speed of 1500 rpm, so the axis can run at a stable operating point across common industrial speed ranges. Power conductors enter through a plug situated at a connector on side B, helping keep cable stress away from the bearing zone in horizontal or vertical orientations. Closed-loop velocity regulation is supported by an integral tacho generator that produces 3 V/1000 rpm, delivering a linear feedback signal to the analog drive controller.

Winding code KD matches the resistance and inductance tables used by MAC drive amplifiers, which helps limit current overshoot during acceleration. Classified as a motor for analog drives, it interfaces directly with voltage-controlled current loops rather than digital field-oriented algorithms. A standard blocking brake holds the load when power is removed, which is useful on vertical axes and other applications that require load retention at standstill. The feedback assembly is specified as tacho feedback and a second shaft end, so an auxiliary encoder, resolver, or belt pulley can be added without disturbing the primary output shaft. This arrangement also supports rear-side accessory mounting when the application requires additional feedback or a secondary mechanical connection.
