The square frame asynchronous motor MQ series has been specially engineered to achieve reduced dimension high performance in variable speed applications with flux vector type controllers. They were born due the great experience of two important companies in the field of industrial automation: Magnetic Motors & SicmeMotori.
The main feature is in the laminated stator pack which carries out the functions of the frame and integrates the air circulation system. In particular, these motors, even though they are sensibly more compact, make it possible to achieve very high specific powers with regard to a standard motor with the same shaft height.
The distinctive electromagnetic and mechanical design permits operation in constant power mode at maximum speeds of up to 8000 RPM. The efficient stator cooling system uses an auxiliary fan to combine the benefits of reduced dimensions and high, continuous, low-speed torque capability.
