Product Description:

The MAC090C-0-KD-4-C/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Supplied for use with analog drive amplifiers, this unit converts amplifier commands into controlled shaft torque and speed for conveyor axes, tooling heads, and general-purpose positioning stages in automated manufacturing cells. Its design aligns mechanically with other MAC090 frame motors.

It mounts through a centering pilot of 110 mm, allowing repeatable alignment against gearbox or machine frames. Heat is removed by natural convection, so no external blower or liquid circuit is necessary. Adequate clearance around the housing helps dissipate heat during operation. The motor reaches a nominal speed of 1500 rpm, a value matched to drive stages that regulate frequency and current for constant torque. Mains and feedback cabling exit through a right-angle connector on side A, simplifying routing inside cabinets positioned on that end of the machine. Internal windings follow the KD code, which identifies the resistance and inductance combination required for analog current controllers to achieve stable bandwidth.

Position feedback and velocity loop closure are obtained through a sensor package that supports incremental or absolute encoder operation and includes a tachogenerator. The tacho produces 3 V/1000 rpm, enabling the analog drive to monitor real-time speed without digital processing overhead. Signal accuracy is supported by the motor's standard tacho quality, which helps maintain stable speed feedback during normal operation. Mechanical holding at rest must be provided externally because the motor is supplied without a blocking brake. This arrangement is suitable for axes where stopping force is handled by the drive or by external machine hardware.
