Product Description:

The MAC090A-0-ZD-3-C/110-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed to pair with analog velocity and position controllers, this model supplies controlled rotary motion to industrial axes such as indexing tables, packaging actuators, and light material-handling stations. Its electromechanical design accepts dynamic load changes while maintaining feedback integrity, making it a functional component for precision automation tasks that rely on continuous closed-loop control.

Its mechanical interface centers on a 110 mm pilot diameter that fits standard Indramat gearbox flanges and maintains shaft concentricity during assembly. Heat is dissipated solely by natural convection, eliminating the need for auxiliary blowers or liquid circuits and simplifying cabinet layouts. Under rated conditions, the rotor turns at 1500 rpm, a speed chosen to balance torque production with vibration limits for mid-range automation loads. Motor power is supplied through a plug oriented as a connector on side B, which keeps the cable run away from the driven machine side. The electromagnetic system follows the ZD winding code, matching phase resistance and inductance to legacy MAC analog drives and helping maintain stable control response.

The motor’s motion feedback architecture uses tacho feedback with a second shaft end, giving the drive electrical speed data and providing a convenient mechanical takeoff for external encoders or couplings. Tachogenerator output is 3 V/1000 rpm, allowing the analog controller to scale velocity signals without additional signal conditioning, and this voltage level is standard within the MAC family. The motor is supplied without a holding brake, so the load must be secured through drive torque or a separate brake during power-off conditions.
