Micro Cooling Fan stator

Since the "Micro Cooling Fan" stator is stationary, so the rotor rotates under the force of. Commutator DC motor is a special apparatus, and by changing the composition of a number of segments, each two adjacent commutator intermediate insulating sheet. The surface of the commutator by a spring pressing the fixed brush, "dota2雷竞技预测 " to the rotating armature winding is coupled with an external circuit. When the rotor turned at an angle, the commutator will access another supply voltage winding, and continue to produce a magnetic field in the winding Seen, due to the presence of "dota2雷竞技预测 " commutator, the armature coil by the electromagnetic torque remains unchanged, the electromagnetic torque acts in the armature to rotate.
