This invention relates to a wheel driven mechanism for a vehicle such as a wheelchair, an electrical bicycle, or a motorcycle, especially to a vehicle which has a wheel driven by power but without using an independent electric motor. The wheel driven mechanism comprises a rotor, a plurality of permanent magnets, a stator, and a plurality of electromagnets. The rotor is divided into a first block and a second block, and the permanent magnets are disposed within the first block to reduce the weight and the cost of the wheel driven mechanism. Furthermore, the user can easily rotate the handwheel mechanism during power off.本發明有關於一種用以驅動車輛行進的動力輪,例如可用以驅動輪椅、電動腳踏車或摩托車等,特別是指透過動力輪進行驅動而不需要設置有電動馬達的車輛。動力輪包括有一轉子、複數個永久磁鐵、一定子及複數個電磁鐵,其中轉子被區分為一第一區塊及一第二區塊,並將永久磁鐵設置於轉子的第一區塊內,而轉子的第二區塊內則未設置有永久磁鐵,藉此將有利於降低動力輪的重量及製作成本,此外更易於使用者在電源關閉的情況下推動該動力輪。20...動力輪21...轉子211...第一區塊213...第二區塊22...電磁鐵組221...第一電磁鐵組223...第二電磁鐵組23...永久磁鐵241...第一連接桿243...第二連接桿25...定子26...電磁鐵27...軸心
