Abstract:
The purpose of this paper is to investigate opportunity to create a new type AC induction motor with the salient pole rotor (without winding) and both winding AC excitation and short circuited placed on the stator. There are some advantages in this design: The suggested design has a cold rotor. The stator short circuited and excitation windings are easier for cooling. The rotor has reduced weight in compare with regular induction motor rotor. The short circuit winding can be used for the current control like in the regular induction wound-rotor machines. In this case, the problem maintenance of the slip rings is eliminated. In this paper, we discuss theoretical opportunity for realization the induction mode operation in two and three phase machines. As a base for this, it serves the analyses operation of one phase machine. This analysis is fulfilled in comparison with regular induction motors with short circuited and wound-rotor windings. Experimental verification was fulfilled in specially designed one phase machine, two phase and three phase machines. Design two and three phase machine demands use two windings for each phase like in regular induction machines. The results of this paper in connection with our previous publications shows that it is possible to design all type of traditional AC and DC machines on base of the salient pole rotor (without winding) and all winding placed on the stator.
