Product Description:

The MAC090A-0-ZD-4-C/110-A-1/WI524LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drives, where velocity or current reference signals are converted into controlled shaft motion for automated axes. Closed-loop operation lets the connected drive correct torque and speed in real time, which helps the motor maintain repeatable movement during positioning and regulated-speed tasks. This makes the unit suitable for machinery that depends on stable rotary response during continuous operation.

A centering diameter of 110 mm secures the flange to a gearbox or machine housing with minimal radial runout. The shaft reaches a nominal speed of 1500 rpm when the rated current is supplied, giving the motor a useful operating point for moderate-speed axis duties. The motor uses natural convection for heat dissipation, so air around the housing must remain free to circulate during operation. The stator winding uses code ZD, which corresponds to electrical values matched to MAC drive amplifiers of the same designation. Power and protective earth conductors enter through a connector on side A, keeping the cable exit on one side of the motor and simplifying layout inside compact machine frames.

The motor is equipped with a standard blocking brake that locks the shaft when the drive is disabled, helping prevent load drift on vertical axes and during standstill. For speed monitoring, a tachogenerator delivers 3 V/1000 rpm, and its standard tacho quality provides linear feedback for velocity loops. The feedback configuration supports tacho feedback, incremental encoder, or absolute encoder versions, so the controller can use the signal format required by the application. Position loops rely on an incremental encoder with standard mounting that is prealigned inside the housing, which avoids field calibration after installation.
