ABSTRACT:
A compact-sized, high-efficient, and high-speed electric blower has high centrifugal resistance. The electric blower includes a rotor that has a multi-slot rotor winding along which an excitation electric current is supplied through a slip ring by a power supply brush, a stator that detects the position of a magnetic pole of the rotor, and has a stator winding in a pole-focused winding pattern, a centrifugal fan attached to a rotational axis of the rotor, and a casing housing the stator and having a path for wind. In response to the rotor pole position detection signal, a semiconductor switch regulates and controls the electric current through the rotor winding or the stator winding. Semiconductor switches control the electric current through the rotor winding or stator winding in accordance with the detection signal regarding the position of rotor magnetic pole.
