Product Description:

The MAC090A-0-ZD-4-C/110-A-1/DI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it accepts analog velocity and current references from legacy drive amplifiers and turns them into controlled shaft motion. In automated assembly lines, its primary purpose is to keep tooling, indexing tables, and conveyor sections synchronized with upstream control signals, allowing older control platforms to maintain precise positioning without migrating to digital feedback networks.

A centering diameter of 110 mm keeps the stator coaxial with couplings and gearboxes so radial runout stays within alignment limits. Heat is removed through natural convection, so no external blower or liquid circuit is required and the motor can operate in enclosures where forced airflow is limited. The rated speed is 1500 rpm, which is the nominal operating speed when the drive card issues its standard reference voltage. Electrical characteristics correspond to winding code ZD, with phase resistance and inductance matched to MAC-series analog amplifiers. A standard blocking brake is integrated to hold the shaft when power is removed, preventing back-driving on vertical or high-inertia axes.

Field wiring is routed through a connector on side A, allowing short cable runs when the motor is mounted with its front flange toward the cabinet. The built-in tacho delivers 3 V/1000 rpm, providing a proportional speed signal to the control loop, while position data comes from an incremental encoder with shock-damped mounting that resists vibration in stamping or cutting machines. For applications that need higher resolution, the feedback assembly also supports incremental or absolute encoder variants without mechanical changes, allowing the sensor type to be matched to the drive card and required accuracy.
