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
