Product Description:

The MAC090C-0-KD-4-C/110-B-1/WI524LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts power from a companion amplifier into controlled torque and speed for machinery axes that require repeatable motion. This operating style suits transfer, indexing, and positioning tasks in automated equipment where stable speed response is important. Its 090 frame size and rugged stator design make it suitable for assembly equipment, pick-and-place gantries, and material-handling workstations used in general automation.

The motor has a 110 mm centering diameter, which provides concentric alignment against gearboxes or mounting flanges and helps minimize runout during installation. Heat is removed through natural convection, so no external blower or liquid circuit is required when the motor operates within its normal load range. The rotor reaches a nominal speed of 1500 rpm, which matches legacy analog velocity loops that reference 50 Hz base frequencies. Incoming power is routed through a sealed connector on side B, keeping service access separate from feedback cabling on the opposite face. A built-in tacho generator produces 3 V/1000 rpm, and position data is supplied by an incremental encoder mounted in the rear housing, so the motor can support both speed feedback and position tracking in classic control layouts.

The electromagnetic characteristics correspond to the KD winding, which indicates the coil impedance and voltage constants used with drives that supply regulated armature current. Shaft holding during machine idle or power loss is provided by a standard blocking brake, which helps prevent unwanted axis movement when external holding hardware is not used. For installations that favor digital supervision, an incremental or absolute tachofeedback encoder option is available. The integrated tachometer maintains standard accuracy so velocity deviation stays within normal analog controller tolerances, and that makes the motor suitable for systems that still rely on established feedback methods.
