Commutator tips:
1. 2 The place is said, the rotor, brush does not move, then a pair of contacts each contact piece is different, and then go on to maintain that he continued to turn, and turn when a group of positive power winding, the other group can reverse power efficiency and higher power output.
2. Part of each group at least one winding piece of exposure, if it is more than multi-winding motor windings may be a common contact plate is also possible. There are contact pads and winding connection, and then top with brush.
3. If not installed, you can not change direction, then the current has been flowing through a winding, and winding reaches zero crossing position (the position of the magnetic field) after the sub will not go, simply can not turn and twist are screw fixed . This time has been energized, the resistance is small, it will burn the rotor.
4. As the commutator and brush of the continuous movement of the rotor does not move, so that when the rotor and the brush is now a group of coils connected to form loops, because there the magnetic field around the power conductor, then he will turn, after this group will rotate will power off and then the next group, so you can keep going to maintain functioning.
