Abstract
The disclosure relates to a three-phase electric motor that uses high magnetic energy permanent magnets and that has a low detent torque. The motor consists of a rotor with N pairs of poles and of a stator portion with teeth extending radially from an annular gear. The teeth have windings and the ends thereof comprise an arc of circle, the middle of which is located on a radius Rand two sides defining an alpha angle, the vertex of which is located on a radius R. The ratio R/Ris substantially equal to (1+/−0.26/N), and the alpha angle is between 110 and 135°.
