The role of dc Motor for Toys capacitors on toy motors:
The DC small motors in the toys are mostly DC permanent magnet motors. When the rotor rotates, the current of the rotor is the power supply that is contacted by the brush and the commutator to supply the rotor windings. During operation, the contact point has sparks and generates electromagnetic waves. The capacitor is used to eliminate or reduce electromagnetic interference. Generally, it is not necessary to connect electrolytic capacitors of 100uf /10v in such a large value, and only need to connect 103-104 non-polar capacitors. But even if a larger capacity capacitor is connected, as long as the capacitor is normal, charging is only an instant matter, and it will not rotate normally after a few minutes. Remove this capacitor and then power up the experiment to see if there is any change in the situation. If it is normal, the electrolytic capacitor will have serious leakage or reverse polarity. If it is still abnormal, the problem is in the motor itself. It can be disassembled to check the oil bearing and rectification of the motor. Whether the child and the brush are normal.
The role of a small motor
Small motors are used in all walks of life to provide the power and speed for these mechanical devices. Its main function is four words: deceleration and boost.
Small motors are widely used in small-scale, automated mechanical equipment, especially in packaging machinery, printing machinery, color box machinery, small production lines, conveyor belts, conveyor belts, electronic equipment, automation equipment, die cutting. Punching machine, silk screen printing machine, slitting machine, food machinery, chemical, textile equipment.
