Abstract
An electric machine comprises a stator, a rotor and an air gap between the stator and the rotor. The stator includes a stator member, a stator winding, an insulating coating between the stator winding and the stator member to provide electric insulation between the stator winding and the stator member, and a local depression in the stator member. The insulating coating is disposed in the local depression. The local depression is located on a side of the stator member facing the air gap.
