Synchronous electric motor, range of electric motors, device for closing, shading or protecting against the sun, comprising an electric motor from such a range and method for producing same

A synchronous electric motor comprising:

• a rotor;
• and
• a stator comprising
• an armature comprising:
• a yoke, and
• teeth defining recesses, and
• coils mounted in the recesses of the armature,
• wherein 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 a central axis of the stator,
• wherein the stator is wound by insertion, each coil being 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 the central axis of the stator,
• wherein a height of the armature is between 20 mm and 120 mm,
• wherein an outer diameter of the yoke is comprised between 30 mm and 65 mm, and
• wherein the synchronous electric motor is configured to operate with a closure, occultation or solar protection device.
