Abstract
Various embodiments of the teachings herein include an electric insulation system of an electric motor comprising a conductor with a wire winding in a slot of a laminated core of a stator of the electric motor. Wires in the conductor are potted by impregnating resin on and in a carrier. The carrier is loaded with impregnating resin and is arranged between the winding wires in the conductor. Cavities of the conductor are filled with the impregnating resin. The impregnating resin provides potting for the cavities in the conductor of the laminated core.
Claims15
An electric insulation system of an electric motor, the system comprising:
- a conductor with a wire winding in a slot of a laminated core of a stator of the electric motor;
- wherein wires in the conductor are potted by impregnating resin on and in a carrier;
- wherein the carrier is loaded with impregnating resin and is arranged between the winding wires in the conductor;
- wherein cavities of the conductor are filled with the impregnating resin;
- wherein the impregnating resin provides potting for the cavities in the conductor of the laminated core.
An electric insulation system of an electric motor, the system comprising:
- a wire winding as conductor in slots of a laminated core
- wherein the wire winding and a carrier in the conductor are embedded in a potting compound;
- wherein the potting compound in the conductor is distributed uniformly around the wires and the carrier because the impregnating resin for this purpose is not guided into the conductor from the outside, but rather by means of the carriers which are loaded with impregnating resin in the B state and which remain with the winding wires in the winding.
A method for manufacturing an electric insulation system of an electric motor, the method comprising:
- winding a conductor including winding wire and impregnating resin carriers;
- drawing the conductor into slots of a laminated core of a stator of the electric motor;
- and
- curing the impregnated winding wire/carrier insulation.
