The application was abandoned: examination was not requested within the 36 months following the 09/28/2016 filing, the deadline set by art. 33 of the Brazilian IP Act. The technology is in the public domain in Brazil.
A brushless motor includes a stator and a rotor. The stator includes a stator core and two windings. The stator core includes a yoke, two opposing first teeth, and two second teeth. The windings are respectively wound around the two first teeth. The second teeth are not wound with any winding. The first and second teeth are alternatively arranged. The rotor is received in a space cooperatively bounded by the pole shoes of the main and second teeth. A plurality of slot openings is defined between the pole shoes of the first teeth and adjacent pole shoe of the adjacent second teeth, which reduces the magnetic leakage and increases the motor power density.
