Hello, there are many forms of hybrid car engines, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy. According to the different starting and working modes of motors, they can be divided into single-phase capacitor-started asynchronous motors, single-phase capacitor-started asynchronous motors, single-phase capacitor-started asynchronous motors, single-phase split motors. phase asynchronous motors and three-phase motors.
According to the rotor structure, the motor can be divided into cage induction motor, which youuse, and in wound rotor induction motor. A squirrel cage is a closed coil.
1. When a three-phase asynchronous motor is connected to a three-phase AC power supply with a phase difference of 120 degrees in electrical angle, the three-phase stator winding passes through the three-phase magnetomotor motor. force generated by the three-phase symmetrical current and generates a rotating magnetic field. The magnetic field rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed.
2. The rotating magnetic field and the rotor conductor have relative cutting motion According to the principle of electromagnetic induction, the rotor conductor (the rotor winding is a closed path) generates induced electromotive force and induced force. fluent. The direction of the induced electromotive force is determined by the right-hand rule.
3. According to the law of electromagnetic force,under the action of the induced electromotive force, an induced current will be generated in the rotor conductor which is basically consistent with the direction of the induced electromotive force. The current-carrying rotor conductor is affected by the electromagnetic force in the magnetic field generated by the stator (the direction of the force is determined by the left-hand rule. The electromagnetic force forms an electromagnetic torque on the motor rotor shaft , driving the rotor). The motor rotor rotates in the direction of the rotating magnetic field when the motor when there is a mechanical load on the shaft, the mechanical energy is emitted outward. Since the magnetic flux in the part without short-circuit ring is ahead of the magnetic flux in the part with short-circuit ring, the rotating direction of the motor is the same as the direction of the rotating magnetic field.
The car generator contains water, what shouldI do ?
1. The combustible mixture is too rich. The remaining unburned parts will accumulate on the spark plug electrode and be carbonized, causing the spark plug to flash abnormally until it is damaged by carbonization. The reasons for the fuel mixture being too rich are usually that the carburetor oil level is too high, the carburetor main air volume hole is clogged, and the air filter element is seriously clogged. Additionally, the carburetor choke is blocked and cannot be fully opened, or the enrichment valve is not working properly, which is also the reason why the fuel mixture is too rich.
2. Engine oil leak. During engine operation, if blue or black smoke is emitted from the exhaust pipe, this indicates that excess engine oil has entered the cylinder, resulting inhas the production of a large amount of carbon deposits by the spark plug electrode or its wetting. by engine oil and unable to produce sparks. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check whether the oil volume of the oil pump is too large and whether the rod sleeve seal and check valve are defective. For four-stroke engines, check the piston rings on the piston, especially the oil ring, whether it is worn or not. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are badly worn, the valve guide oil seal is hardened, or the oil seal lip is excessively worn, it will cause the fitting gap to be too large. and the sealing effect is lost. These two abnormal situations will eventually causeuer suction of oil into the valve rocker arm chamber into the cylinder along the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.
3. In the ignition system, the magneto is demagnetized, the wire connections inside the ignition coil and the electronic ignition, the generator output end and the coil input end are demagnetized. The ignition is loose and the ignition timing is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits on the spark plug electrode.
4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the power calselected orifice is one or two gears lower than that specified in the instruction manual, the temperature of the spark plug will rise very high and the heat cannot be dissipated in time, causing abnormal combustion and eventually melting of the spark plug electrode. and cause premature damage. When the spark plug itself is installed and used, some defects are not easy to detect and also affect the ignition performance. For example, if the spark plug is poorly sealed or the spark plug is solid, it should be adjusted or replaced in time. 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.
After the engine floods, initial corrective measures should be taken according to the specific situation to avoid secondary damage to the vehicle. Find out the key to the problem and. fix. Damage to the car was minimized.
After understanding the specific situation, if you find that water has entered the engine, you should remove the spark plug and artificially prevent the fuel supply system from starting and d ignition, so that the water in the engine can be drained successfully.
Once the inspection is complete, use compressed air to treat the electrical connections inside the motor to prevent water from corroding them.
The parts to pay attention to are: the fuse box, the sensor socket and the body water accumulation area.
After cleaning, test drive the vehicle to ensure normal engine operation during use.
Repair Guide for Flooded Vehicles
1. The passage of water represents less than a third of the tire:
The passage of water is divided into ddifferent degrees and levels. If your car only wades slightly in the water, less than a third of the tire size, then you don't have to worry too much. You can eliminate hidden dangers as long as you do a little inspection yourself.
Check if there is any trash attached to the chassis. Rain in Beijing is acidic and will corrode paint and tire rubber. To protect the paint and tires of the car, the car should be cleaned in time. .
2. Water flooding up to one third of the tire:
If the water reaches more than one third of the tire, clean the sound insulation cotton in time.
Having the tire flooded more than a third of the way is the limit for repairing it after wading through water. Because if this limit is exceeded, water will penetrate upwards through the water-permeable holes in the vehicle floor, thereby wetting the sound insulation cotton inside the chassis.
