Product Description:

The MAC090A-0-RD-3-C/110-A-0 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Designed to operate with analog velocity or torque drives, it converts low-level command signals into controlled shaft rotation for automated handling, assembly, and processing stations. By integrating electromagnetic feedback and a rigid housing, the unit provides the stable dynamic response needed for coordinated multi-axis motion. Its compact servo design makes it suitable for equipment that requires repeatable speed control, steady torque production, and dependable operation in established analog drive systems.

The motor is supplied without a blocking brake, so position holding after power removal must be handled externally by the drive or by a mechanical lock. Thermal energy leaves the frame by natural convection, which eliminates the need for a fan and keeps the installation layout simple. Electrical power reaches the stator windings through a connector on side A, helping keep cable routing direct at the motor connection point. Rotor speed is reported through tacho feedback, using an analog tachogenerator that produces a voltage proportional to shaft speed and supports stable velocity regulation in conventional analog control systems.

A 110 mm mounting pilot serves as the centering diameter, helping align the flange concentrically with the driven machine. The shaft extends through the rear to provide a second shaft end, which can be used for auxiliary mechanical coupling or external signal pickup when the application requires it. Classified as a motor for analog drives, the unit is intended for systems that rely on voltage-compatible feedback behavior and matching motor constants. Motion quality is supported by a standard tacho quality rating, which helps maintain smooth speed response and consistent control behavior across normal operating conditions.
