Coil for stator of electric motor, stator and manufacturing process

A coil of a stator for an electric motor,

• the coil comprising:
• a bobbin which forms a tooth of the stator,
• the bobbin comprising:
• a tubular central shaft comprising a plurality of channels formed along its perimeter between a first end of the bobbin that is configured to face toward the center of the stator and a second end of the bobbin that is configured to face toward the outside of the stator,
• wherein the channels are configured to receive a turn of a winding wire wound around the bobbin;
• a first retaining flange situated on the first end of the tubular central shaft,
• a second retaining flange situated on the second end of the central shaft;
• and
• a winding wire configured to be wound in the form of turns around the bobbin,
• wherein the ends of the winding wire are positioned at the first end of the bobbin so as to enable electrical connections toward the center of the stator,
• wherein the bobbin comprises a material cutout extending between the first end and the second end of the bobbin, and
• wherein the material cutout is configured to receive the winding wire and allow the passage of the winding wire between the first end and the second end of the bobbin.
