Product Description:

The MAC090A-0-ZD-2-C/110-A-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, it converts commanded voltages into controlled rotary motion for position and speed control in industrial machines. The motor fits legacy automation lines that use the size 090 mechanical envelope while maintaining closed-loop regulation through its integrated tachometer. Because the feedback device is integrated into the motor, the connected drive can monitor actual motion without requiring a separate standalone tachometer assembly.

A centering pilot of 110 mm allows the motor to align precisely with gearbox flanges or machine plates. Rated running speed is 1500 rpm, a value that suits indexing tables and slow-running process heads that still require smooth control. This moderate base speed helps applications that favor smooth low-speed operation over very high top-end velocity. Thermal management relies on natural convection, so heat leaves the housing without external blowers or liquid circuits. The ZD winding sets the resistance and inductance values expected by the matching analog drive. A spring-applied blocking brake holds the shaft when power is absent, helping prevent drift on vertical or load-bearing axes.

The motor supplies speed feedback through tacho feedback, permitting the drive to regulate velocity in real time. Power conductors terminate at a connector on side A, keeping cable entry consistent with layouts that place incoming lines toward the machine front. That arrangement can simplify routing in machine frames where the motor faces forward. The speed signal amplitude is 3 V/1000 rpm, so the analog controller receives a proportional voltage across the operating range. The transducer is built to standard tacho quality, which provides stable signal behavior for general-purpose motion tasks. It is intended for established servo installations that depend on proportional analog speed feedback rather than digital encoder channels.
