Product informaon
Product descripon
The MQA asynchronous servo motor for precisely controlled moon.
The naturally venlated MQA asynchronous servo motor is suitable for applicaons that
require a high dynamic performance, high construcon-related operaonal reliability and
precisely controlled moon.
In connecon with the i700 and i950 servo inverters, Servo Drives 9400, and Inverter Drives
8400 TopLine, high-performance drive soluons in the torque range from 66 to 1100 Nm can
be obtained.
Customer benet
•Opmum controllability and high dynamic performance thanks to low moments of inera
•Opmal smooth running characteriscs for exact work results
•Wide speed seng range
•Field weakening operaon usable
•Robust resolvers are included as a standard, and incremental encoders or absolute value
encoders ensure a high precision
