Product Description:

The MAC090C-0-KD-3-C/110-A-0/110-A-1/S001 is a compact AC servo unit manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive controllers, the motor delivers continuously regulated torque to automated presses, material handling axes, and general machine tools. Its purpose in industrial automation is to translate commanded current into predictable shaft rotation while supplying a tachometer-based speed signal to the drive for closed-loop stabilization of velocity.

Mechanical alignment is simplified by its 110 mm centering diameter, which locates the stator housing concentrically on the machine frame and minimizes radial runout. Thermal management relies on natural convection, so fins on the housing move heat to the ambient air without an external blower or liquid circuit. At steady state, the rotor turns at 1500 rpm, a mid-range speed suitable for gear-driven indexing tables. The integrated tachogenerator outputs 3 V/1000 rpm, giving the analog controller a linear feedback voltage for velocity loops. All three power phases reach the stator through a single connector on side A, allowing cable ducts on the service side of the machine to remain short and accessible.

The KD winding code identifies the electrical winding arrangement, and its impedance permits high stall current without saturating the magnetic circuit. The motor is supplied without a blocking brake, so a vertical axis requires an external holding device or energized torque to secure the load. The unit includes tacho feedback and a second shaft end, making it possible to add an encoder or resolver for position feedback while retaining the analog tacho signal. Consistent speed detection is supported by the tachogenerator’s standard accuracy class, which helps keep gain settings stable across the operating range.
