What configuration do Wave windings use for their coils?

Wave windings use a series configuration for their coils. In this arrangement, the coils are connected end to end in such a way that the output from one coil feeds directly into another. This method allows for increased voltage output, as the voltage from each coil adds together. In a series configuration, the same current flows through all the connected coils, which is beneficial for generating a more uniform magnetic field and efficient operation of the machine.

Additionally, the layout of wave windings facilitates a smoother distribution of magnetic flux and helps in achieving better performance of the motor or generator. This differs from parallel or mixed configurations, where coils could be connected in a way that produces varying currents or voltages, which may not be ideal for the specific operational requirements of devices utilizing wave windings.
