具体实施方式
为了能够更清楚地描述本发明的技术内容，下面根据图1至图4结合具体实施例来进行进一步的描述。
如图1及图2所示，依据本发明的一实施例的一风力及自给动力发电装置100，包含： 一风叶组件1，包括一扇叶11及一传动轴杆12，扇叶11用以承载风力而旋转，传动轴杆12传动连接于扇叶11以传递扇叶11的旋转运动；一第一发电机2，第一发电机2传动连接于传动轴杆12，以受传动轴杆12的带动而发电；一马达3，电连接于第一发电机2，且传动连接于传动轴杆12，马达3通过第一发电机2发电的电能而转动传动轴杆12；以及一发电装置4，包括一第二发电机41、一最大功率追踪器(Max Power Point Tracking,MPPT)42以及一蓄电组件43，第二发电机41传动连接于传动轴杆12，以受传动轴杆12的带动而发电，最大功率追踪器42电连接于第二发电机41与蓄电组件43之间，而在最大功率追踪器42的控制下而将第二发电机41发电的电能储存于蓄电组件43。
本发明的风力及自给动力发电装置100可以是定点设置，也可以是装设在如交通载具等移动物体上。如图2所示，扇叶11朝向交通载具的前方，当交通载具前进的速度越高，扇叶11所承载的风力也越大，转速越高。
在本实施例中，风叶组件1的扇叶11为涡卷式叶片。而在其他实施例中，扇叶11也可以是螺旋式叶片、球形叶片或百叶式叶片。扇叶11的旋转运动因此传动轴杆12作为旋转轴心。传动轴杆12为单一根转轴，将扇叶11、第一发电机2、马达3以及第二发电机41传动连接，以将扇叶11的动力传递给第一发电机2。而在其他实施例中，传动轴杆12也可以因此齿轮、皮带轮、变速机等传动连接的多根转轴，亦能将扇叶11的动力传递给第一发电机2。
详细而言，扇叶11承载风力而旋转。扇叶11的转速达一定值时，能通过传动轴杆12带动第一发电机2以使第一发电机2发电。第一发电机2的电力输出端电连接于马达3的电力输入端，马达3为接收第一发电机2发电的电能而顺向转动传动轴杆12，而形成动力反馈结构。当第一发电机2发电量越大，马达3转动传动轴杆12的力也越大。第二发电机41通过传动轴杆12的旋转而发电。此外，通过最大功率追踪器42的设置，使第二发电机41能以最大的功率输出对蓄电组件43充电，以供其他用电设备使用。
在本实施例中，第一发电机2是直流发电机。马达3为匹配的直流马达。而在其他实施例中，第一发电机2可以是交流发电机，马达3也可以是交流马达。
第二发电机41是直流发电机，输出的电压可以是12V、24V、36V、48V、60V、72V、84V或96V等。最大功率追踪器42为一控制器，电连接于第二发电机41与蓄电组件43之间。在本实施例中，蓄电组件43为蓄电池。在一般运作状态下，最大功率追踪器42能在不同的风力条件下运作于最大功率点，以将使第二发电机41能以最大的功率输出对蓄电组件43充电，而具有最佳的电能使用效率。而在蓄电组件43充饱电时，最大功率追踪器42不再 运作于最大功率点，使第二发电机41的输出功率调降至符合需求。
如图3及图4所示，依据本发明的另一实施例的风力及自给动力发电装置100a，本实施例与第一图的风力及自给动力发电装置100大致相同，主要差异在于：第一发电机2、马达3、第二发电机41于转轴上的排列顺序不同。第一发电机2、马达3与第二发电机41是设在同一根转轴上，排列顺序不影响各个组件所发挥的功效。
以上的叙述以及说明仅为本发明的较佳实施例的说明，本领域技术人员当可依据所界定保护范围以及上述的说明而作其他的修改，只是这些修改仍应为本发明的发明精神而在本发明的保护范围中。
