The asynchronous motors MQ series have been specially engineered to achieve reduced dimensions, high performances 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 electrofan to combine the benefits of reduced dimensions and high, continuous, low-speed torque capability.

They are three-phases asynchronous motors with squirrel-cage, low losses laminated sheet with square frame visible from external of motor, a compact structure independent electrofan to obtain the following characteristics:

- High power with relation to the external size
- Small external dimensions
- High rotation speed (up to 8000 rpm)
- Maximum and continuous torque are available even at low speed
- Small moment of inertia of the rotor
- Degrees of protection IP54 and IP23
- Dimensional and power comparability with direct current motors.
- Ventilation and speed transducer incorporated in the motor structure
- High mechanical robustness
- High precision of rotation speed
- Insulation class F (CEI EN60034-1)

They are available with 10 different shaft height (frame size 100-132-160-180-225-280-355-400-450-500 mm) with power ranging from 2,5 to 3600kW. In addition the MQ motors can also be manufactured with larger shaft height sizes on customer’s request.

Standard mechanical protection degree available are: closed solution in IP 54 and an open solution in IP 23. Other solutions are available upon request.

The cooling of the motor is provided by an axial or radial electric fan, mounted in the rear of the motor (no drive end side of coupling).

It is assumed that the environment is:
dry, i.e. with relative humidity of the air below 75%. However, an excessively dry atmosphere (below 20% relative humidity) can cause commutating difficulty (excessive brush wear).
clean, i.e. without appreciable quantities of dust and dirt in general, suspended in the air.
free of chemical agents, i.e. without concentrations of gas or vapours that could chemically harm the copper, iron, aluminium,paints and insulation.

Sicme MQ Series AC motors can also be installed in difficult environments (damp, dusty, chemically harmful, etc.) but in this case the degree of protection, method of cooling and possibly the choice of materials must be agreed upon prior to ordering.

All MQ Series motors may be installed in environments with temperature down to –15°C and stored in environments with temperature down to –30°C.
