Product Description:

The MAC090A-0-ZD-3-C/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drive systems, the unit supplies controlled torque and speed to industrial axes that rely on real-time velocity feedback for precise motion. By pairing with associated servo controllers, it supports automated production lines, pick-and-place stations, and other equipment that demand accurate yet straightforward electromechanical actuation. The motor is suitable for indexing tables, transfer devices, and feed axes where stable analog response is more important than integrated digital functions. Its straightforward layout also fits machinery that uses established servo hardware, separate control electronics, and long-running analog motion loops.

The motor employs a ZD winding that allows continuous operation at a nominal speed of 1500 rpm, matching common converters used in legacy analog loops. A centering diameter of 110 mm aligns the housing with mechanical interfaces, helping reduce runout at the mounting flange. Heat produced by the stator is dissipated through natural convection, so no external blower or liquid jacket is required. Velocity feedback is derived from a permanent-magnet tacho generator that delivers 3 V/1000 rpm, supplying an analog signal proportional to shaft speed for closed-loop regulation. This arrangement supports steady speed control without adding separate external feedback hardware or extra alignment components at the machine.

Feedback hardware is arranged as tacho feedback on a second shaft end, providing a direct mechanical reference point while keeping the drive side free for couplings or pulleys. The motor has no blocking brake, so holding torque during power-off must come from external clamping devices or the drive itself. Power conductors exit through a connector on side A, which can simplify routing when the connection area must remain on the same side as adjacent machine wiring. The tacho signal is intended for conventional speed loops and supports stable operation in established analog control systems. This layout keeps the motor easy to integrate on machines where space around the shaft and cable entry is limited.
