Patent ID: 7288906

Claim:
A manually operated brushless direct current (DC) motor, comprising: a power source; a set of magnets; a rotor with coil wire wound around, and placed between the magnets by means of a rotation axle; a set of bearings used to support the rotation axle, and to provide the connection required between the coil wire of the rotor and the power source without a brush; a set of switches electrically connected to the bearings and the power source respectively; a set of sensor plates, hung around one of the bearings by a wire; and a set of sensors installed at specific places to detect the existence of the sensor plates, and generating a responsive signal; wherein the alternatively pressed switches work just like brushes of a conventional motor and make the rotor to rotate; and wherein the sensors detect the sensor plates intermittently passing by when the rotor rotates to drive the sensor plates moving upward and downward (back and forth).
