Abstract
A synchronous electric motor includes a rotor and a stator. The stator includes an armature and coils. The armature includes a yoke and teeth. The teeth define recesses. The coils are mounted in the recesses of the armature. The stator is wound by insertion. Each coil is formed from a wire outside the stator, so that the coils are subsequently inserted into the recesses, through wire passages of the recesses according to a direction radial to a central axis of the stator. Furthermore, a ratio of a surface area of each recess to a thickness of the yoke is between 5 mm and 10 mm, the surface area of each recess being measured in a plane perpendicular to the central axis of the stator.
