Q:How does the communication motor work?
Tesla coil to form a rotating magnetic field, rotating magnetic field in the cage of alternating flux change, squirrel cage induction electromotive force formation, formation of induced current, induced current in the magnetic field force, produce with rotation, when balance, motor steady work.
Q:Which is good for dc motor and ac motor?
The family seems to be alternating current, so it should be alternating current. Direct current also seldom listens
Q:What is the power of ac motor
In calculus, the voltage takes the square root of the maximum voltage.I hope my answer will help you.
Q:Who made the world's first ac motor?
In 1867, the Belgian character ram was made into an improved alternator. Scientists in 1886, the Croatian American origin tesla made two phase winding type ac asynchronous motor model, and in 1888 and developed the principle of the tesla coil, and in 1891 made the tesla coil's patent, which laid a foundation for alternating current (ac) of the remote transmission. It can be said that Edison and tesla, the former is not the inventor of the direct current (dc), the latter is not the inventor of the alternating current (ac), the later this misconception is that from the current war at the end of the 19th century, because two people a stick to dc, another promote communication, and let people think they are dc and ac inventor (baidu encyclopedia "tesla" entry is written).
Q:What happens to the ac motor plus dc
The electric fan that home belongs to the motor of the asynchronous motor Bilateral induction principle, it is the principle of the three-phase alternating current from the stator side, with conductor can produce electromagnetic field around it after the power supply, and then you think, because he is a three-phase alternating current, size and phase is changed over time, so here is the key, the magnetic field generated by the change of three-phase alternating current is also must change, is actually a rotating circular magnetic field, the magnetic spin cutting rotor - - into the shaft of the electric fan blades is understandable, by Faraday electromagnetic induction principle, or lenz theorem, would induce electromotive force on the rotor, resulting in a rotating torque spin. You said with direct current situation, in the understanding of this principle is not hard to find, after due to add on the stator dc direction are the same size, won't produce rotating magnetomotive force, so the fan will not turn, unable to work. There are some things that I want to help you with
Q:The power consumption of a three-phase ac motor is equal to the line voltage cross current. How do you explain?
Line voltage, the line current indicates the input of the motor, and of course it is related to the actual power consumption of the three-phase motor. But you should also multiply by the square root of 3, and multiply by the power factor, which is the actual power consumption. I estimate that the questioner does not understand the difference between line voltage, line current and phase voltage and phase current. Line voltage and line current is standing on the power supply, or standing on the outside to consider the problem of electrical equipment, and the phase voltage, phase current is standing on the internal electrical equipment to consider a problem. A physical quantity such as power is a global quantity, and the use of line voltage and line current is of course more convenient and direct.
Q:In the ac motor, he is excited, excited, and excited. What is the difference between
He is excited to have another power supply excitation coil (stator coil) Series of excited, stator coils with armature coils And excitation, the stator coil is in parallel with the armature coil
Q:The structural difference between ac motor and dc motor
Rotor (2) : part of the rotor is the key to master, there are two kinds of rotor, squirrel cage and wound rotor. To master their own characteristics and differences. Cage type used for medium and small power motor (below 100 k), he has simple structure, reliable work, convenient in operation and maintenance. Wound rotor can improve startup performance and adjust the speed, size of air gap between the stator and rotor, will affect the performance of the motor, the general thickness of air gap between 0.2 1.5 mm. Grasp the connection method of stator winding. 2. The working principle of three phase asynchronous motor Master formula n1 = 60 f/P, S = (n1 - n)/n1, n = (1 - S) 60 f/P, at the same time understand the meaning of their (very important), to be able to apply these formulas, to calculate. At the same time, remember: usually motor slip under rated load of SN is about 0.01-0.06. Examples of the book to grasp key. 3. The data on the three-phase asynchronous motor nameplate models: (1) master the example of the book.
Q:The ac motor is not positive and negative, so how do you achieve positive and reverse?
Ac motor? Single item of pole type electric motor does not turn positively! Three exchanges of any two phase sequence will be easy if you have more mundane motors!
Q:The difference between a converter motor and a regular ac motor
The structure design Structure design, main is also considering the non-sinusoidal power characteristics of variable frequency motor insulation structure, the influence of vibration and noise cooling mode, generally pay attention to the following questions: 1) insulation level, which is generally F or higher, strengthens the insulation strength of the ground and turns, especially considering the ability of insulation to withstand shock voltage. 2) to the problem of vibration and noise of the motor, the motor should be fully considered component and overall rigidity, trying to improve its natural frequency, in order to avoid and every force wave resonance phenomenon. 3) cooling mode: the general adoption of forced ventilation cooling, the main motor cooling fan is driven by an independent motor. To prevent shaft current measures, the bearing insulation measures should be applied to the capacity exceeding 160KW motors. Mainly produces magnetic circuit asymmetry, also can produce shaft current, while the rest of the high frequency component generated by the current role in combination, shaft current will increase greatly, which can lead to bearing damage, so often insulation measures. For constant power frequency converter motor, the special lubricating grease should be used to compensate the temperature of the bearings when the speed is over 3000 / min.
