Product Description:

The MAC090C-0-KD-4-C/110-A-0/WI520LX/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for use with analog velocity and position controllers, it supplies accurately regulated torque and speed to automated axes in material-handling, packaging, and general-purpose machinery. Acting as the electromechanical actuator in these systems, the motor converts electrical input from the drive into precise rotary motion while integrated feedback elements keep the control loop closed and stable. This arrangement suits automated axes that require repeatable motion without a separate standalone feedback package.

At its nominal speed of 1500 rpm, the motor uses winding code KD, which indicates the stator's electrical resistance, inductance, and thermal loading limits. Accurate centering during installation is provided by a 110 mm pilot diameter on the mounting flange. The flange pilot helps align the motor housing with the mating machine surface before the mounting bolts are tightened. Heat generated in the windings is dissipated by natural convection, so unobstructed airflow around the housing is required for continuous duty. This cooling method keeps the motor housing simple because no auxiliary blower is mounted on the unit. Power conductors terminate through a connector on side A, allowing routing that avoids the encoder end when the motor is paired with conventional analog amplifiers.

Position and velocity signals originate from an incremental encoder that works in parallel with tachometer feedback rated at 3 V/1000 rpm. This combination lets the controller respond to commanded speed changes while also tracking shaft position. Together, these signals provide pulse-train position data and a proportional voltage for speed regulation in the connected controller. The output shaft includes a shaft seal to restrict lubricant migration and protect internal bearings from splash exposure. Because the unit is supplied without a blocking brake, any static holding requirement must be met by the external transmission or by drive torque. Classified as a motor for analog drives with standard tachometer quality, it is intended for compatible analog drive systems without additional option modules.
