    摘要: An electric motor has a field pole formed by a field current passing through a field winding. A voltage booting converter converts output voltage of a battery and outputs the voltage between a power source line and a grounding line. Field winding is electrically connected onto an electric current channel between battery and power source line and formed so that voltage switched by a switching element is applied to both ends. A controller controls the field current so as to adjust density of magnetic flux between a rotor and a stator by performing switching control on switching element and a switching element connected in parallel to field winding and converts the output voltage of battery into voltage in accordance with a voltage command value.

    摘要: A die includes a cavity in which a powder magnetic core material is introduced and a recessed curved surface curved inward of the die formed at the bottom surface of the cavity. The powder magnetic core material in the cavity is pressed by a pressing surface of a punch to the side and bottom surfaces of the cavity to form a split tooth body. As a result, a projected curved surface having a shape following the recessed curved surface is formed on the outer peripheral surface of the split tooth body. Then, two split tooth bodies are butted and joined together at the surfaces to which a pressing force by the punch is applied, and thereby a tooth is assembled.
