BRUSH-LESS DC DYNAMO AND A VEHICLE COMPRISING THE SAME

This invention provides a brushless dc dynamo, which is characterized by using semiconductor switches to replace commutators used in conventional brush DC dynamo, wherein the periodically mechanical contact of the armature and different electrodes are replaced with static electronic switching array to periodically switch electrically without any mechanical contact switching between the armature and electrodes. Meanwhile, the armature can work as conventional mode to always maintain the distribution of the armature current such that the magnetic field of the rotator is perpendicular to the magnetic field of the stator during rotating, and the damage of switched contacts caused by mechanical contact of the armature and electrodes can be avoided.
