The building system and the mathematical model of axial air-gap three-phased asynchronous motor

The paper presents a new type of motor with axial air-gap which has been manufactured practically. The new elements concern the two stators poles disposition as well as the winding building and some technological elements. The building shape will be an advantage in an electric traction use. One has presented the building manner, the operating mode, and the elaborating mathematical model where the electrical parameters calculation way becomes concrete for this new motor. The motor we have proposed gets real advantages: less material; less energy for variable load; opportunity to be manufactured with two synchronism speeds on the condition the two stators not be supplied simultaneously; possibility of successive brakes. The equivalent circuit are presented in the general reference K and one shows the manner they can be particularized in other reference systems
