Product Description:

Bosch Rexroth Indramat manufactures the MAC090C-0-KD-4-C/110-A-0/WI520LV/S005 within its MAC AC Servo Motors series. The unit is a motor for analog drives, intended for use with external control electronics that regulate motion through commanded electrical input and continuous speed feedback. It converts command signals from a matching controller into controlled shaft rotation, letting automated machinery index, feed, or position loads with repeatable accuracy on assembly, printing, and material-handling stations.

The mechanical interface uses a centering diameter of 110 mm, allowing the housing to seat precisely against standard IEC mounting faces and helping keep motor alignment consistent during installation. Thermal energy leaves the stator by natural convection, so no forced-air accessories are required when ambient airflow is available around the housing. The motor uses a KD winding, which sets the resistance and inductance expected by compatible legacy analog amplifiers during current control. Position data comes from an incremental encoder mounted in the factory location, while speed feedback is supplied by the integrated tacho generator for closed-loop operation. Under nominal loading, the shaft reaches 1500 rpm, giving stable speed for indexing duties and slow-speed contouring in positioning axes.

Power conductors are brought in through a connector on side A, simplifying cable routing and keeping strain relief on a fixed plane when the motor is installed in compact equipment. The built-in tacho generator outputs 3 V/1000 rpm, a level that many analog velocity loops can read directly without added signal conditioning in established drive systems. A shaft seal is installed to protect internal bearings from coolant splash and to keep grease inside the motor during routine machine operation. The design is delivered without a blocking brake, so static holding torque must be supplied by the drive or by an external clamp when the axis is at rest. This layout is useful where the machine does not rely on a mechanical holding function during normal stops.
