A magneto is actually a permanent magnet rotating in an iron core. The primary coil on the iron core induces an electromotive force (called the primary potential). When the breaker contact closes, a current (called the primary current) is generated. When the breaker contact suddenly When the primary current is turned on and suddenly cut off, the secondary coil induces a relatively high electromotive force (called the secondary potential), causing the spark plug to trip. In order to get the strongest spark plug flashover, the maximum secondary potential should be obtained; in order to obtain the maximum secondary potential, the breaker contact should be closed when the primary potential is zero, and open when the primary potential is maximum.
The stator of the ATV is divided into multiple poles and has little to do with their output lines. However, the greater the number of poles, the higher the generator power and the stronger the output current. Common ATV magnetic motors are divided into single-phase motors and three-phase motors.
When installing a magnetic motor, pay attention to the relationship between the magnetic shaft, the breaker, and the camshaft. The magnetic axis rotates through the neutral position 80 ° -100 ° in the direction of rotation. (The position angle, this position is equivalent to the magnetic pole of the magnet 2-3mm away from the shoe. If it is not correct, although all the coils and parts of the magnetomotor are normal, the magnetomotor may not give out sparks at all.) The electrical contacts have just opened. If this is not the case, loosen the contact base plate fixing screws to adjust.
