Abstract
The invention relates to a rotary multi-phase electrical motor wherein stator teeth corresponding to one same phase are grouped on a distinct and magnetically isolated stator section. The number of teeth per stator section is an odd number of a value of at least three and the difference between the total number of stator teeth and the number of rotor permanent magnet poles is one. The teeth are preferably equidistantly distributed along the stator. The invention also relates to a wheel motor using the rotary multi-phase electrical motor described above.
