steel is the rotor and the coil winding is the stator. Magneto is the main power supply of
electrical system.
3. Basic parameters
The rotor consists of six magnets with 12 poles;
Stator winding has a total of 18 poles, which connect according to three-phase △ and
the winding resistance value of each phase is 0.3-0.5 Ω; horsepower: 168W / 5000r / min
(cold state) (maximum attenuation of hot engine is 8%).
4. Failure mode rotor magnetic steel is broken;
Faded magnetic properties of the magnetic steel;
Stator winding short circuit to ground; Stator winding inter-turn short circuit;
Fall off and open circuit of welding points of stator winding;
Friction damage between rotor and stator (foreign matter entering).
Voltage regulating rectifier
1. Outline drawing
2. Working principle
The three-phase sinusoidal alternating current which fluctuates with the speed of the
magneto is converted into a stable direct current through a full wave rectification and
controllable voltage stabilizing charging circuit. The voltage regulating rectifier provides
power to the load and charge the battery.
3. Basic parameters
Structure type: three-phase full-wave rectifier, short circuit type; Adjustment voltage:
14.5V ± 0.5V;
