Problems solved by technology

[0012] However, in the described configuration, in order to simplify the manufacturing process, it is desirable to wind the stator teeth independently of each other, which can be problematic since a single wire must be used to form the corresponding coil subgroup

Embodiment Construction

[0031] The described embodiment of the invention is a winding device for placing coil windings on stator teeth. After the coil windings are placed on the stator teeth, the stator teeth are arranged to be mounted on the stator back iron to form the stator. The stator forms part of an electric motor or generator, wherein the electric motor is preferably used in a wheel. But motors can be used for any purpose. The motor is of the type in which the stator is radially surrounded by a rotor carrying a set of magnets for attachment to the wheel. The definition of electric machine is intended to include generators. Furthermore, the electrical machine winding device is suitable for electrical machines with a rotor mounted centrally in radially surrounding coils.

[0032] To illustrate, image 3 One embodiment of a stator tooth 300 adapted to mount to a protrusion formed on the stator back iron after a coil winding has been wound on the stator tooth is shown.

Abstract

A winding device for installing a coil winding on a stator tooth, the winding device includes: a mounting part having a first mounting arm for receiving a first stator tooth and a mounting arm for receiving a second stator tooth a second mounting arm, wherein said first mounting arm is movable relative to said second mounting arm between a first position and a second position; for when said first mounting arm is relative to said second mounting arm means for mounting an electrical conductor on said first and second stator teeth when in a first position to form coil windings on said first and second stator teeth; placing the first mounting arm in a second position relative to the second mounting arm when the body has been mounted on the first and second stator teeth to allow the first and second stator teeth to A mechanism for removing stator teeth from said first and second mounting arms, respectively.

Description

technical field [0001] The invention relates to a coil winding arrangement, in particular an arrangement for winding coils on stator teeth. Background technique [0002] As we all know, the stator is the stationary part of the motor or generator around which the rotor turns. The stator generally includes magnetic parts and other structural parts. The working principle of the motor is that the current-carrying wires are under force in the presence of a magnetic field. Typically, a rotor carrying a set of permanent magnets is arranged to rotate around a set of coils mounted on a stator, the coils being arranged to carry current causing the rotor to rotate around the stator and generate motion. It should be understood that it is also possible for the rotor to carry a set of coils and the stator to carry a set of permanent magnets. [0003] Examples of stators arranged to fit inside a rotor are figure 1 shown. figure 1 A stator back iron is shown, formed from a single piece...
