Product Description:

The MAC090A-0-RD-4-C/110-A-1/AM164SG belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a permanent-magnet servo motor intended for analog drive systems in which external amplifiers provide precise torque and speed regulation. Within automated machinery, the unit converts electrical commands into controlled rotary motion for indexing tables, packaging axes, and material-handling actuators. Its feedback arrangement allows the connected controller to monitor motor movement and correct deviations caused by changing loads. This closed-loop operation supports accurate positioning and stable speed control during repetitive machine cycles.

Mechanical alignment is aided by a centering pilot of 110 mm, allowing repeatable mounting against gearboxes or machine frames. Heat generated in the stator is removed through natural convection, so the installation does not require an additional blower or liquid-cooling circuit. Power conductors terminate through a connector on side A, simplifying cable routing when nearby machine components restrict access to the housing. The unit is classified as a motor for analog drives, and its voltage characteristics and feedback arrangement are compatible with drive cards that process continuous signals. A standard blocking brake is integrated at the non-drive end to hold the shaft when operating power is removed. The brake is released electrically during normal operation, allowing the motor to rotate in response to commands from the connected amplifier.

Speed monitoring relies on a generator with standard tacho quality, which supplies a voltage proportional to motor speed for the analog controller. This signal allows the amplifier to regulate velocity continuously as the commanded speed or mechanical load changes. Absolute position information is supplied through an absolute encoder, allowing the control system to determine the shaft position after power-up without relying only on incremental movement data. The combined tacho and encoder feedback supports both velocity regulation and position-controlled operation through the same motor assembly. Encoder and tacho signals use a shared multipin connection, reducing the number of separate feedback cables required around the motor. The feedback arrangement is suitable for machine axes that require controlled acceleration, repeatable stopping positions, and stable operation under varying loads.
