提出了电动车或轮椅的非接触电能传输启动和驱动方法。采用矩形和螺旋线圈的初级和次级绕组，分别为非接触式发电站。超过200瓦的电力被传输到一个制造的EV电机设置。EV是由CLPS驱动的紧凑型原型车，装有轻质电池。电池提供了一部分的瞬态电流所产生的电动汽车启动和加速。此外，我们提出了一种非接触式电力传输使用一种新的米德型线圈。相对于负载位移稳定传输功率的量和抑制电磁噪声发射的有效性是曲折型线圈的特征。当发射器线圈的节距对应于接收器形状时，发射最大功率。采用始终保证发射线圈和接收线圈相对位置的电路实现了一种有源励磁系统。并进一步明确了系统的最佳磁通分布。

Starting and driving methods of contactless power transmissin to electric vehicles or wheel chair were proposed. By employing rectangular and spiral coils for primary and secondary windings, respectively, for contactless power station. Electric power over 200 watts was transmitted to a fabricated EV motor setup. The EV is a compact prototype driven by CLPS, loaded with a light-weight battery. The battery supplies a part of transient current arising from starting and acceleration of EV.Furthermore, we propose a contactless power transmission using a new meader type coil. Effectiveness for stabilizing the amount of the transmitted power against a load displacement and suppressing electromagnetic noise emission is the features of meander type coils. Maximum power is transmitted when the pitch of the transmitter coil corresponds to the receiver shape. An active excitation system was realized using circuit in which the relative position between transmitter and receiver coils are always assures. Furthermore the optimal distribution of magnetic flux was made clear for the system.
