Q: Single phase synchronous alternator working principle: From the point of basic electromagnetic circumstance, a dc motor can be working for motor operation in principle, can also be used as a generator to run, are only different constrained conditions. On the two brush end of the dc motor, and dc voltage, input power to the armature, mechanical energy output from the motor shaft, drag the production machinery, become motor converts electrical energy into mechanical energy, such as prime mover drag dc motor armature, and without dc voltage on the brush, the brush end dc electromotive force can be drawn as dc power, output power, motor become generator converts mechanical energy into electrical energy. The same machine, which can be used as an electric motor or as a generator, is called the reversible principle in the theory of electric motors

Q: How does the ac motor work? What can you do to change why?: The principle of alternating current motors: the coils spin in the magnetic field. At work, energy is converted into kinetic energy

Q: How to judge a three-phase ac motor: Three-phase resistance line resistance is measured with meter, first to see if there is resistance, and then to the equilibrium value is decrease (maximum minimum), general corporate control within 1% resistance unbalance degree, resistance unbalance affects a relatively high fever, insulation damage easily.

Q: What is the difference between dc, alternator motor, and how the motor works: Current generator can be expressed with trigonometric function: I = A * Sin (W * t + Kuai), that "Kuai" is for the early phase, A representative of A current maximum (valid values are: SQR (2) * I (effective) = A), SQR (2) on behalf of the square root of 2). The direction of current change twice per cycle (positive direction and negative direction), our country's frequency alternating current (ac) of 50 hz, period of 0.02 s, said current direction 50 times per second (don't know how this place remember correctly).

Q: Why does a single motor have a series of capacitors: In a three-phase current, the current in each phase of the phase is in itself a phase difference. The capacitor induction motor has two winding, namely the starting winding and the running winding. The two windings vary by 90 degrees in space. String on the startup winding capacity of a large capacitor, when running and start the windings by single alternating current (ac), because of capacitor in the startup winding current on time than the running winding current advance Angle of 90 degrees, to reach the maximum value. In time and space form two of the same pulse magnetic field, make the air gap between the stator and the rotor produces a rotating magnetic field, under the effect of rotating magnetic field, the induced current in the motor rotor, current and rotating magnetic field interact to produce electromagnetic torque, motor rotation. This is why uniphase motors are connected to capacitors.

Q: How does ac motor speed control: Buy the speed adjustment machine ~ 4 files ~ the external one governor ~ can be adjusted More expensive,

Q: Three-phase ac motor star row and delta connection?: The design of this circuit is still controlled by the principle of time. The difference is that when starting the motor stator windings into star, each phase winding withstand voltage of power supply phase voltage (220 v), reduces the starting current impact on power grid. In its late starting, it according to the setting time for pick up in advance to delta connection, each phase winding withstand voltage of the power line voltage (380 v), into the normal operation of the electric motor. This kind of circuit is available for the squirrel-cage asynchronous motor, which is connected to a triangle in normal operation

Q: What is the starting method of ac motor?: The starting method of ac motor is mainly: direct start-up, star delta start-up, auto-de-voltage start, soft start and frequency converter start-up.

Q: What is the difference between the three-phase ac motor and the second phase: Single-phase motor inside there are actually two sets of windings, a set of winding is work, also is the main winding, a set of start winding, namely vice winding, single-phase motor due to the single-phase power supply, so won't produce a rotating magnetic field in the winding, but the pulse magnetic field, pulse magnetic field does not produce torque, so the motor won't turn, so let's give him a start winding, the power of the startup winding is from the power supply of the main winding, but with the phase shifting device such as the capacitance that current phase by phase shifting device after the current is different, also became a so-called two-phase, so inside the windings creates a rotating magnetic field, motor will turn up, I would say the rotation of the three-phase motor principle, are all the same!

Q: 380v's ac motor operates under 330v voltage: It is normal to be able to be driven, the difference is a few dozen volts different, it is only to calculate to be able to discover, the surface is not visible to the naked eye.
