Product Description:

The MAC090A-0-ZD-4-C/110-B-0/WI511LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The unit serves as the rotary element in analog drive systems. It translates command voltages into closed-loop angular motion for indexing tables, feeders, and other industrial automation axes. This control method supports smooth speed changes and repeatable positioning during cyclical machine operation.

The ZD winding code identifies the coil impedance used with legacy analog amplifiers, helping the motor pair correctly without phase mismatch. Under rated conditions, the rotor reaches 1500 rpm, giving predictable speed where 1 V of tachometer output corresponds to 500 rpm. Mechanical alignment is aided by a 110 mm centering diameter that locates the housing on precision machine plates. Heat produced in continuous duty is removed through natural convection, eliminating the need for auxiliary blowers. For electrical integration, the stator terminals are brought out through a connector on side B, allowing the cable bundle to be routed away from the load side and reducing interference with feedback lines.

The motor is intended for analog drives, so its tachogenerator supplies a fixed reference for velocity loops. That generator delivers 3 V/1000 rpm, which matches the gain expectations of Indramat drive cards and maintains proportional speed feedback across the working range. The tacho is built to standard tacho quality, which helps the controller filter ripple without additional hardware. For position control, an incremental encoder with a standard mounting flange is integrated, and the feedback arrangement also allows use of an absolute encoder when position retention after power-down is required. The encoder supports position tracking during coordinated moves, while the tachogenerator provides the analog speed signal used by the drive. The rotor is held solely by drive torque because no blocking brake is present, which lowers inertial load and simplifies end-of-shaft service access.
