A method of manufacturing a rotor is disclosed. A magnet is inserted into a magnet hole of a rotor core. The method comprises inserting an insertion member into the magnet hole having a first opening and a second opening. The method comprises fixing the magnet to the insertion member extending out from the second opening. The method comprises inserting the magnet, which is fixed to the insertion member, into the magnet hole from the second opening by pulling the insertion member extending out from the first opening in a direction separating away from the rotor core. The method comprises cutting the insertion member extending out from the first opening.

A rotor of a rotating machine includes a rotor core in which a plurality of assembly holes is provided in an axial direction, and a first magnet and a second magnet. The first magnet and the second magnet are assembled to the rotor core by being inserted into the assembly holes in accordance with a predetermined arrangement pattern. An outer peripheral surface of any one of the first magnet and the second magnet, including end faces in the axial direction, being entirely covered with an insulating coating, and an outer peripheral surface of the other of the first magnet and the second magnet, excluding at least a part of end faces in the axial direction, being covered with an insulating coating.

An electric motor suitable for use in a laundry machine comprises an improved stator and/or rotor design.

This electrical steel sheet includes a base steel sheet, a first insulation coating formed on a first surface of the base steel sheet and having adhesiveness, and a second insulation coating formed on a second surface of the base steel sheet which is a back surface to the first surface and having adhesiveness, in which an average pencil hardness of the first insulation coating is HB or higher and 3H or lower, and an average pencil hardness of the second insulation coating is higher than the average pencil hardness of the first insulation coating.

This electrical steel sheet is an electrical steel sheet in which at least part of either or both surfaces of a base steel sheet is coated with an insulation coating having an adhesive ability, wherein a logarithmic decrement of the insulation coating in a temperature range of 25 to 100° C. is 0.3 or less.

In a method for impregnating, strengthening or electrically insulating a body supporting single or multi-layer windings, in particular for an electric machine, the body supporting the windings is submerged into a multi-component resin system or is sprinkled with the multi-component resin system or is sprayed with the multi-component resin system.

A rotary electric machine includes a stator housed in a housing, the stator having a stator body formed by a stack of stator laminations, the laminations are generally non-circular and being angularly offset with respect to each other, so as to form spaces with the housing, the housing having ducts for the flow of a coolant, and said spaces also being used for the flow of the coolant.

A stator for an electric machine and a method for its manufacture are specified, said electric machine having a laminated core around an axial direction that, in a first overmoulding between a first axial end and a second axial end, is surrounded by a first plastic material having several grooves, into which the stator windings having a first winding head and a second winding head that are connected to several connecting contacts are supplied, wherein in a second overmoulding, a second plastic material fills the grooves around the stator windings and at least covers regions outside of the first winding head on the first axial end and outside of the second winding head on the second axial end.
