ABSTRACT:
A controller is disclosed for a motor. The motor includes a first terminal and a second terminal. In a positive mode, the first terminal is connected with the positive electrode of a power supply, and the second terminal is connected with the negative electrode of the power supply. In a negative mode, the first terminal is connected with the negative electrode, and the second terminal is connected with the positive electrode. The controller includes a central conductive device comprising a first conductor connected with the positive electrode of the power supply, a second conductor connected with the first terminal, a third conductor connected with the negative electrode of the power supply and a fourth conductor connected with the second terminal. An upper conductive device includes a first conductor for contacting the first and second conductors of the central conductive device and a second conductor for contacting the third and fourth conductors of the central conductive device in the positive mode. An upper conductive device includes a first conductor for contacting the first and fourth conductors of the central conductive device and a second conductor for contacting the second and third conductors of the central conductive device in the negative mode. An upper magnetic device can attract the upper and lower conductive devices to the negative mode. A lower magnetic device can attract the upper and lower conductive devices to the positive mode.
