The starter is a special electric motor designed to start a gasoline or diesel engine for a short time. It features thick wires and a unidirectional undercarriage on the shaft head. The operating current reaches several hundred amperes.
The generator is a three-phase generator designed to work for a long time, and the rectifier is directly made of the housing. Early products produced DC power directly.
Can an ordinary motor be used as a generator?
Motors are reversible: mechanical power input --- the motor can become a generator;
< p> Electrical power input- --The motor can become an electric motor (motor).So as long as your motor provides mechanical power (use the main motor to turn it), it can generate electricity.
Considerations should also be taken into account whene the specific implementation: 1) Connection to the electricity network to produce electricity; it's very simple, as long as its speed exceeds the synchronous speed, it can generate electricity and produce power. to the electricity network.
2) It is more difficult to operate alone to power the load. The capacitor must be connected in parallel to the output end to provide it with a capacitive reactive current to excite it as the output power increases; , the capacitor connected in parallel must The capacity must also be increased.
What type of engine are you referring to? Any DC motor used in small appliances (the type that requires batteries) can be used as a generator, but it puts out power at the rated speed. the electrical voltage is lower than its rated voltage and it is much smaller. When I was in high school, I used the electric motor of a vehiclefour-wheel drive cule with a small wheel attached to the rear wheel of a bicycle to increase speed, and electricity could only slightly light an ordinary small light-emitting diode. . If they are larger appliances, like electric fan motors, no, they are single phase asynchronous motors and cannot be used as generators. Even if you use an external force to make them rise, there will be no electricity production, because this. is caused by the internal structure. Most industrial motors, regardless of their size, cannot be used because most of them are three-phase asynchronous motors. Like single-phase asynchronous motors, their structure determines that they cannot be used as generators since they do not contain magnetic poles. ! There is no excitation mechanism. If it is a rare DC motor, it can be usedread in generator mode. Additionally, if it is a synchronous AC motor, its structure itself is reversible, and it can also be a generator.
