Electric motor and radiator fan

An electric motor comprising:

• a rotor rotatably mounted about a rotational axis extending in an axial direction;
• and
• a stator provided with a laminated core, forming a stator yoke, a number of stator teeth extending radially from the stator yoke, and a number of reinforcing elements,
• wherein each of the stator teeth are T shaped and include a tooth-base side forming pole tabs extending in a circumferential direction defined by the stator,
• wherein the stator defines a stator slot and a slot opening, wherein the stator slot is disposed between a first stator tooth and a second stator tooth, adjacent to the first stator tooth and configured to receive coils of a stator winding, wherein the slot opening is formed between a first pole tab and a second pole tab facing the first pole tab,
• wherein the first pole tab forms a first bearing shoulder and the second pole tab forms a second bearing shoulder,
• wherein a reinforcing element of the number of reinforcing elements includes a narrow side and a wider side, the wider side wider than the narrow side, the narrow side facing the first pole tab and defining a cutout forming a contour, and
• wherein the reinforcing element is inserted into the slot opening and the contour engages the first bearing shoulder to hold the reinforcing element between the first pole tab and the second pole tab,
• wherein the contour is configured to minimize a contact area between reinforcing element and the first bearing shoulder.
