Commutator device composed as follows: (A) If you do not install, then it can not change direction, the current has been flowing through a winding, and winding through the zero position they will not reach the sub down, simply can not turn and twist are screw fixed this time has been energized, since the resistance is small, it will burn the rotor. (B) part of each set of windings at least one pair of contact piece, if the motor winding is more likely a plurality of windings of the common contact piece is possible. Contact piece and winding connections, and then top with brushes. (C) the rotor rotates, Brush does not move, then each contact pair of contact pieces are different, then maintained he continues to turn down, but when the turn of a group of winding is driven positive, another group can get more energized reverse high efficiency and power output. (Iv) continued movement of the rotor brushes does not move, so that when a group of current and brushes rotor coil connected to form a loop around the conductor due to the presence of a magnetic field is energized, then he will turn, it will break the post-rotation this group then the next group will be electrically powered, so you can maintain the operation continues to go up. |
