Novel Technique to Start DC Motor Using Wireless Power Transfer

Abstract

This paper represents the “Wireless start & control DC motor”. There is multiple needs and
multiple uses for such technology. Our team chooses to research the feasibility of wireless
power transmission through the inductive coupling. This wireless power transmission
consists of using a transmission and receiving coil as the coupling coils. The first benefit to
using this inductive coupling for simplicity of transmission & receiving antenna and second
for small power transmission. This is much safer means of conveyance. To transfer power an
alternating current should be passes through a closed loop coil. The primary coils
alternating current will create a time varying magnetic field. The flux generated by this time
varying magnetic field will then induced voltage on secondary coil. So the transmission
distance is reduces then efficiency of any system using inductive coupling improve efficiency.
