This paper proposes a new concept for a tail cordless elevator system. The tail cords bring a vibration and a leaning of the elevator car in skyscrapers because tail cords become long and heavy. The proposed system has rechargeable batteries on the car and electrical energy is supplied at specific floors by a contactless electrical energy transmission. This system needs a transformer which has high coupling rate. This paper shows some simulated results and experimental results of the transformer shapes for a tail cordless elevator system. The developed transformer, which has 10 mm gap, has a coupling rate of 0.88 and can supply the power at 91% efficiency.
