  • Patent number: 11196322
    Abstract: In a method for manufacturing an electric motor comprising a rotor and a stator a placeholder for a temperature sensor is inserted in the axial direction between a first coil layer and an adjacent second coil layer of a winding head such that the placeholder is situated in a gap-shaped recess extending between the first and the second coil layers, the first coil layer is then pressed onto a circumferential surface of the placeholder and onto the second coil layer and is plastically deformed such that a space between the lateral surfaces of the two coil layers and the circumferential surface of the placeholder is reduced, and a contact surface between the lateral surface of the first coil layer and the circumferential surface of the placeholder is enlarged. By removing the placeholder, a receiving chamber is subsequently formed in the winding head, into which a temperature sensor is then inserted.
