Abstract

A method for winding a coil for electric machines, and a coil wound according to this method. The method comprises the following steps: placing a wire against a form, leaving a first length of the wire and a second length of the wire extending from the form, wherein the first length has a first end and the second length has a second end; winding the first length in a first direction round the form, such that the first end of the first length is ending in an outer layer of the plurality of layers; winding the second length in a second direction round the form, wherein the second direction is opposite the first direction, wherein the second end of the second length is ending in an outer layer of the plurality of layers, wherein all layers and levels of the coil are filled.

Description

technical field [0001] The present invention relates generally to coil winding, and more particularly to a method for winding a coil for an electric motor, and a coil wound according to the method. Background technique [0002] Problems with prior art [0003] Concentrated coils are used for the winding of a fairly wide range of types of motors. A well designed motor is usually characterized by a high slot fill factor providing high thermal conductivity within the slot, which improves heat dissipation from the conductors to the core. A high slot fill factor can be achieved when there is little insulation, impregnation material or air between the conductors in the slot and no coil turns protrude laterally. For many machines, the best shape for the coil is a rectangular or parallelogram shape to follow the shape of the slot and allow the coil to be inserted into the slot. [0004] In order to make a strong reinforcing coil, one usually uses a form on which the coil is wound...
