- Q:What will be the result of the power supply to ac motor after the rectifier (not filtering)?
- The ac motor will not be able to transfer the pulse direct current, the light is hot.
- Q:Brushless dc motor, is it ac motor or dc motor? Why is that?
- Dc, of course! Brushless dc motor actually a lot of time is said to be ac motor, because of the dc is converted to communicate by oscillation circuit, so it actually is the essence of communication, we just at the time of judgment is dc or ac is the type of the input circuit. I hope I can help you.
- Q:What are the advantages of the dc welder and ac welder? The better one?
- compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '
- Q:About 100W ac motor is better than dc motor
- The answer is very specific. Ac motor and dc motor are used for different purposes, you can reconnect according to the theory, the industry experience of your relevant industry is applied. That would be better.
- Q:The type of speed adjustment of ac motor and the difference between them
- Speed regulating pole change motor -- -- -- -- -- - a specific motor internal to do particular winding, by motor different connection mode change polarity logarithm, get a different speed. Formula: the synchronous speed of ac motor is 60f/magnetic poles (f - - frequency), the magnetic poles are changed and the rotational speed is changed. The drawback is that it cannot be stepless speed adjustment (such as 2-4 pole motor, synchronous speed only two gears, the two poles are 3000, and then the 4 pole is 1500.
- Q:How to distinguish dc motor from ac motor?
- Relative decision, according to the purpose of the use dc motor energy saving, high power factor, but need to convert ac to dc, need to increase the current transformer, cause high cost; The ac motor is easy to use, the structure is simple, the relative noise is too loud, please make the decision according to the demand
- Q:Why does ac power connect capacitor
- The purpose of ac motor capacitance is to transfer the single phase alternating current to a phase difference of 90 degrees. The two phase alternating current (ac) into two groups and four groups, each motor coil winding, is formed in the motor rotating magnetic field, rotating magnetic field to produce induced current in the motor rotor, rotating magnetic field and the magnetic field produced by induced current in the opposite direction, by rotating magnetic field into a state push-pull rotation.
- Q:How to eliminate the electromotive force of ac motor
- It is wrong to eliminate the anti-electromotive force of ac motor, which is the electromotive force that is opposite to the electromotive force of the power supply. There are multiple power sources in the circuit that can be turned against electromotive force. For example, two metal bars that cut the magnetic field in the same way back to the road may have an anti-electromotive force. There may be an anti-electromotive force in the presence of the electromotive electromotive force and induced electromotive force. In the case of a coil, the current of the electric current changes in the end of the coil. For example, the variation of voltage between the inductors in the LC oscillator circuit is strongly associated with the anti-electromotive force. The electromotive force is also produced when the motor coil is turning.
- Q:Can alternator speed improve power generation?
- As long as the network is connected, the speed of the generator is synchronous with the electromagnetic system, not fast or slow. The amount of power generated is determined by the torque of the rotor. From the physical structure, the stator and rotor of the generator are completely independent and non-interference parts. Generator stator active source, produce inductive electromotive force, current and drag of the rotor, the exporting of alternating current (ac), by a prime mover (oil, gas, air, water, etc.) determines the amount of active power. Reactive power source, winding of generator rotor is direct current (dc) is introduced from the external magnetic field, under the impulsion of drag, outward flow of reactive power alternating current (ac), determined by the input of rotor dc size the size of the reactive power.
- Q:How to change ac motor to dc motor
- You might as well turn the direct current into an alternating current to make it easier to use the inverter to convert the dc point to ac
