Product Description:

The MAC090A-0-RD-2-C/110-A-1/S001 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Intended for machinery that accepts analog velocity or torque references, it transforms those commands into tightly regulated shaft rotation for pick-and-place axes, feeders, and indexing tables throughout automated production lines. Its 090 frame size and A frame length give it a compact housing that suits installations where mounting space is limited but stable servo response is still required. This type of motor is commonly used where the drive amplifier closes the speed loop from an analog feedback signal and the machine requires smooth axis control during repeated motion cycles.

A centering diameter of 110 mm aligns the stator housing concentrically with the machine frame, which helps keep radial runout low. Heat is removed through natural convection, so no external blower or liquid circuit is required. The integral tachogenerator is supplied in standard tacho quality, providing an analog speed signal for general-purpose loop regulation. Power conductors exit through a connector on side A, and a spring-applied, electrically released blocking brake locks the shaft when the inverter is disabled. The side-exit connection also helps route cabling away from couplings, guards, and moving slides on compact machine frames.

The unit is designed as a motor for analog drives, so it can work with control systems that use continuous command, feedback, and excitation signals. Because of that arrangement, the motor fits established machine platforms that rely on analog speed feedback rather than digital encoder communication. Its RD winding code identifies the electrical configuration used for this frame size and supports the operating characteristics expected by compatible servo amplifiers. The integrated brake also supports applications where the shaft must remain fixed after power is removed. The winding selection matches the thermal and electrical behavior expected by compatible servo amplifiers, helping preserve stable response under changing load conditions.
