... with ferrite magnets. Also in this area, drift in the direction of brushless motors can bee seen, because of higher efficiency, longer lifetime, lower noise, better EMC and more controllable torque vs speed characteristic. There are different technological solutions, which can been used in the area...

..., more advanced brushless motor technology, usually three phases, can be found. The complex comparison between the both groups is presented in Table III and Figures 8 and 9 . It can be seen that brushless motor Figure 9 has got generally less part number compare to bush type motor (Figure 8...
