A Novel Approach for Catching the Flux Leakage in Induction Machines Using Wireless Power Transfer

In this paper, a guide for the design and construction of a receiver coil to catch the power losses caused by the flux leakage of an induction motor has been presented. The characterization methods for the wireless power received are also provided. In this work we derived the proper relation between induction motor windings and receiver coil to receive the maximum power possible. The equivalent circuit of the proposed system is introduced along with the circuit theory to analyze the system. The design and characterization method for the receiver are provided. For effective wireless power receive, the proposed system need to be set at 50Hz. Two receivers with multiple circular winding are constructed. One placed at the front of the motor coils and the other is placed at the back of the same motor coils. Using these types of receivers at both sides of the inductive motor, a purely free wireless power transfer of about watts is achieved.
