Product Description:

The MAC090A-0-ZD-2-C/110-L-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it interfaces directly with the corresponding MAC amplifiers that issue current and velocity commands through proportional analog voltages. The unit converts those signals into controlled mechanical power for axes found in machine tools, conveyor pick-and-place heads, and packaging equipment. Its electromagnetic layout provides mid-range torque while keeping the frame compact, letting several motors fit in close proximity on multi-station assemblies without excessive weight or footprint.

Under rated operating conditions, the rotor reaches 1500 rpm, a speed suitable for gearless couplings to moderate-speed tooling or feed screws. Alignment to the driven machinery is guided by a 110 mm centering diameter that seats the stator concentrically inside precision bores. Heat is removed through natural convection, so the housing ribs must remain exposed to ambient airflow rather than being enclosed. Winding code ZD indicates the phase resistance and inductance values expected by the analog controller. For velocity feedback, the internal tacho generator produces 3 V/1000 rpm, delivering a linear voltage proportional to shaft speed that the drive uses for closed-loop regulation.

The mechanical shaft is supplied without a blocking brake, so external clamping or continuous motor current is required to hold vertical or overhauling loads during power interruptions. Power enters the stator through a high-current connector positioned on the left side, simplifying parallel routing in cabinets where multiple MAC motors share the same orientation. The sensor pack is configured for tacho feedback, combining the analog tacho signal with commutation tracks to support sinusoidal current control. Signal accuracy is graded as standard, delivering sufficient precision for general motion applications without the use of high-resolution encoders.
