Product Description:

The MAC090A-0-ZD-4-C/110-A-1/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Classified as a motor for analog drives, it is used to provide closed-loop speed and torque control in automated machinery where precise motion is required without digital synchronization. By converting regulated three-phase electrical input into controlled shaft rotation, the unit drives positioning stages, material-handling axes, and other motion elements inside industrial production cells. This arrangement allows the paired drive amplifier to correct speed changes as operating loads vary.

The motor mounts through a centering pilot of 110 mm, which helps keep the flange face and the driven mechanism in concentric alignment. Heat generated by the stator is released through natural convection, so no auxiliary blower or liquid circuit is required. Its nominal operating speed of 1500 rpm suits applications that demand stable velocity while keeping mechanical noise low. Power is supplied through a single connector on side A, which simplifies cable routing when the motor is installed against machine frames. A built-in tacho generator outputs 3 V/1000 rpm, giving analog controllers a proportional voltage signal for real-time speed feedback.

The unit is delivered with a blocking brake as standard, which helps prevent axis movement when power is removed. For applications that require higher feedback resolution, the motor can support tacho, incremental, or absolute encoder signals. Position control is further refined by an incremental encoder with standard mounting referenced in the type code. Coil characteristics follow winding code ZD, which corresponds to the electrical layout used for this motor. To maintain repeatable speed measurement, the motor uses standard tacho quality components that keep calibration stable over temperature and duty-cycle changes.
