Product Description:

The MAC090C-0-KD-4-C/110-A-1/WI524LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It functions as the primary rotary actuator in analog drive systems, translating current from a drive module into controlled torque and speed for machine tools, gantry axes, and automated conveyors in industrial plants. It is a motor for analog drives, so it fits legacy control chains that rely on voltage or current reference commands without digital fieldbus interfaces.

A centering diameter of 110 mm locates the motor precisely on a machine frame, keeping shaft misalignment low and reducing bearing load. Thermal energy is carried away by natural convection, so the housing surface must stay unobstructed for a steady temperature rise during continuous duty. Incoming power reaches the stator through a connector on side A, which simplifies cable routing when the motor is placed against bulkheads or gearboxes. The motor uses winding code KD, which sets the resistance and inductance values expected by the matching analog amplifier. Under rated excitation, the shaft reaches 1500 rpm, a speed suitable for moderate-torque applications that still require smooth velocity regulation.

Shaft position is reported by an incremental encoder with standard mounting, allowing the amplifier to close a fine-resolution feedback loop during operation. The attached tacho generator delivers 3 V/1000 rpm, and its signal quality is listed as standard, giving adequate proportional feedback for analog velocity controllers. The motor includes a standard blocking brake that holds the shaft when mains power is removed, preventing vertical or overhauling loads from drifting. Optional tacho feedback or absolute encoding may also be selected when the application requires a different feedback arrangement.
