Axial compressor with a magnetic stepper or servo motor

The axial compressor 30 may be mounted in the inlet pipe 32 of the compressor housing 26 is disposed upstream of the turbo supercharger 10 from the compressor wheel (16). The axial compressor 30 may increase the pressure ratio to about 1.3. The axial compressor 30 may be driven by a motor 40 such as a magnetic stepper motors, servo motors and cage (squirrel cage) motor. An axial compressor may have a fan 34, a boost (boost) can be controlled by the speed of the fan 34, the fan may be accelerated or decelerated according to the conditions. Magnetic stepper motor 40 it is possible to drive the fan 34 with the fan wheel 36, and the fan wheel has a magnet 44 which is related to the energization available coil 42, the power available coil magnet (44) creates a rotating magnetic field that can follow.
