It can be used as a generator. According to the principle of electromagnetic induction, part of the closed circuit conductor will produce an induced current in the closed circuit when breaking the magnetic field lines. the small motor can be used as a generator to close the circuit. Even though it is the coil in the motor, there are also permanent magnets in the motor, so the magnetic flux lines also have...
Please help Contact me online if there is a problem with setting up a homemade engine modified into a hydroelectric generator. High school student. . .
When a conductor cuts magnetic field lines in a magnetic field, it generates an induced electromotive force which, with the loop closed, creates a current.
The phenomenon of induced electromotive force due to changes in magnetic flux When part of the conductor in a closed circuit moves to intersect the magnetic field linesthat in the magnetic field, a current will be generated in the conductor. . This phenomenon is called electromagnetic induction.
As long as the surface of the closed coil remains unchanged, if the magnetic field intensity changes, the magnetic flux will also change and electromagnetic induction will also occur. The precise definition is therefore as follows: The phenomenon of induced electromotive force due to changes in magnetic flux.
Detailed informationThe main engine classifications are:
1. Hydraulic motor: It is customary to refer to an energy conversion device that produces rotational motion and converts the hydraulic energy supplied by a hydraulic pump into mechanical energy.
2. High-speed motor: The gear motor has the advantages of small size, light weight, simple structure, good workmanship, insensitivity to oil contamination, a resresistance to shocks and low inertia.
3. Vane motor; This is a hydraulic motor in which the blades of the rotor slot are in contact with the housing (stator ring) and the rotor rotates under the action of the incoming liquid.
4. Radial piston motor: It has good reversing characteristics, which makes the motor operation absolutely silent and is suitable for servo systems.
5. Axial Piston Motor: It is a distributed shaft cycloidal hydraulic motor supported by bearings.
6. Low speed hydraulic motor: simple structure, reliable operation, many varieties and specifications and low price.
7. Axial Piston Motor: It is a distributed shaft cycloid hydraulic motor with bearing support.

Can motors produce electricity?
A waterfalle 2.2M with a maximum water height of 2.2M. Take 2M for calculation, and the flow rate is 1L/S. Gravitational potential energy T=mgh, P=mgh/t=1000*10*2=20000J/s=20000/3.6=5.5KW
The efficiency of the original owner's homemade turbine will not exceed not 50% because that's too small.
The motor efficiency will not exceed 85%
The power is therefore conservatively estimated at around 2 kW.
Since the water level is too low, the poster needs an axial flow vane turbine, and he can make one himself. Next, engage the gearbox at high speed. This can achieve higher efficiency.
Since the power is too low, a 3 kW DC motor can be used with a relatively simple structure, and then an inverter can be added.
Motor = generator? I want it When making a hand crank generator, why does the internet say you can use a small motor playst ? Please explain the reason Jijiji
The motor can produce electricity. But there are two types of motive energy production. One is a diesel generator and the other is a gasoline engine generator.
The diesel engine generator works and converts diesel energy into electrical energy.
In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the volume decreases. the temperature rises rapidly, reaching the ignition point of diesel. Diesel ignites, the gas mixture burns violently, rapidly expands in volume and pushes the piston down, which is called "work".
The gasoline engine generator operates and converts gasoline energy into electrical energy.
In the cylinder of the gasoline engine, the mixed gas burns brightlyslowly, expands quickly in volume and pushes the piston down to do the work.
Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thus driving the engine. crankshaft to rotate. By installing the brushless synchronous alternator coaxially to the crankshaft of the electric machine, the rotation of the electric machine can be used to drive the generator rotor. Using the principle of "electromagnetic induction", the generator will produce induced electromotive force. and a current can be generated through the closed charging loop.

Remember that energy can be transferred when yous give When the motor is powered, electricity is converted into kinetic energy (not counting heat production) so when you turn the motor with your hand, the energy from your hand is converted into electrical energy;
You can try using one motor to drive another motor. When motor A is energized and rotating, it will cause the shaft of motor B to rotate and voltage will be output to the brush of motor B. I tried it and it works, but what if I want to make a manual generator , the power of a small motor is limited and the output voltage is lower.
