Abstract
The application discloses coils of an electrical machinery and a method for forming the coil, a stator of an electrical machinery and a method for forming the stator, and an electrical machinery. The method includes: providing a first conductor and a second conductor, a resistivity of the second conductor being lower than a resistivity of the first conductor; obtaining a rated current rising coefficient according to a desired power of the electrical machinery, the rated current rising coefficient being a ratio of a rated current of the electrical machinery with the desired power to a rated current of a reference electrical machinery; obtaining, according to the rated current rising coefficient, a first conductor turn number of the first conductor and a second conductor turn number of the second conductor in each coil; forming the coil according to the first conductor turn number and the second conductor turn number.
