A stator for an electric motor or generator, the stator comprising a circumferential support having a plurality of first engagement elements distributed about the circumferential support, a first resiliently deformable element having a first temperature sensing element mounted on the circumferential support, a plurality of teeth for receiving coil windings, wherein each tooth includes a second engagement element to allow engagement with a first engagement element on the circumferential support for allowing each tooth to be mounted on the circumferential support, wherein coil windings on a tooth are arranged to engage with the first temperature sensing element when the tooth is being mounted to the circumferential support with the first resiliently deformable element being arranged to deform upon the coil windings on the tooth engaging with the first temperature sensing element to move the temperature sensing element from a first position to a second position.

Stator for an electric motor or generator

An arrangement for mounting a coil winding on a stator tooth, the arrangement comprising a mounting element having a first mounting arm for receiving a first stator tooth and a second mounting arm for receiving a second stator tooth, wherein the first mounting arm is movable relative to the second mounting arm between a first position and a second position; means for mounting an electrical conductor on the first stator tooth and the second stator tooth when the first mounting arm is in the first position relative to the second mounting arm to form a coil winding on the first stator tooth and the second stator tooth; and means for placing the first mounting arm in the second position relative to the second mounting arm when the conductor has been mounted on the first stator tooth and the second stator tooth to allow the first stator tooth and the second stator tooth to be removed from the first mounting arm and the second mounting arm respectively.

Coil winding arrangement

A stator or rotor for an electric motor or generator comprising a plurality of teeth for receiving coil windings, wherein each tooth has an injection molded plastic layer formed on a plurality of sides of each tooth with a first gap formed in the injection molded plastic layer on a first side of each of the teeth with a first insulation element placed in the first gap formed in the injection molded plastic layer, wherein the injection molded plastic layer and first insulation element are arranged to electrically insulate the plurality of teeth from the coil windings.
