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.

提出了电动汽车或轮椅非接触式电力传输的启动和驱动方法。非接触式电站的一次绕组采用矩形线圈，二次绕组采用螺旋线圈。超过200瓦的电力被传输到一个制造的电动汽车马达装置。这款电动汽车是一款由CLPS驱动的紧凑型原型车，装有轻质电池。电动汽车起动和加速产生的瞬态电流部分由蓄电池供电。此外，我们提出了一种使用新型介面型线圈的非接触式电力传输。曲线形线圈的特点是有效地稳定负载位移下的传输功率量和抑制电磁噪声发射。当发射器线圈的螺距与接收器的形状相对应时，传输的功率最大。采用总能保证发射线圈和接收线圈之间相对位置的电路实现了主动励磁系统。在此基础上，确定了系统的最佳磁通分布。
