Product Description:

Bosch Rexroth Indramat manufactures the MAC090A-0-ZD-2-C/110-A-0/I01250/S001, a member of the MAC AC Servo Motors series. This motor is intended for analog drive systems where closed-loop control is handled through external amplifiers. In automated cells, it converts electrical power into controlled mechanical rotation for repeatable positioning and stable velocity regulation across gantries, presses, and robotic tooling. Its operating concept suits equipment that relies on continuous current commands rather than modern digital communication between the drive and motor.

The motor uses a centering diameter of 110 mm, so the housing seats accurately in compatible machine frames and helps maintain concentricity with coupled loads. Winding code ZD indicates the stator’s electrical characteristics and the current range used by the drive. Under rated conditions, the rotor reaches 1500 rpm, a speed that balances torque output with thermal limits. Heat is removed solely by natural convection, eliminating the need for forced-air accessories in cabinets with adequate airflow. This passive cooling method also keeps the installation simpler because no separate fan wiring or airflow management is required. Power conductors terminate through a connector on side A, allowing cables to exit toward the driven axis while keeping wiring routes orderly. The motor does not include a blocking brake, so holding torque must be supplied by the drive or by an external mechanical lock.

The integrated sensing package provides tacho feedback so the analog controller can read real-time speed in proportion to shaft rotation. This signal is calibrated at 3 V/1000 rpm, enabling straightforward scaling within drive electronics and predictable matching with analog input circuits. The device follows a standard tacho quality classification, indicating ripple and linearity that suit general-purpose motion axes rather than ultra-precision spindles. As a motor for analog drives, it is intended to pair with legacy velocity controllers that output continuous current instead of digital pulse trains. That arrangement supports stable speed regulation during steady operation and allows the control loop to respond smoothly when machine load changes during a cycle.
