Q:The power consumption of a three-phase ac motor is equal to the line voltage cross current. How do you explain?
This is the basic formula! Validation; Line voltage is equal to phase voltage square root of 3, phase voltage is equal to line voltage over square root of 3, and line current is equal to phase current. Cases; Three-phase symmetric load, line voltage = 380v phase voltage = 219.4 v (phase 3) current each has 10A power factor = 0.8 Compute power; 1. P = square root of 3 U line I line cosine phi = 1.732 * 380 * 10 * 0.8 = 5265.28 w P = 3U phase I cosine phi = 3 * 219.4 * 10 * 0.8 = 5265.6 w (3 phase power) Type; Phase voltage = line voltage/square root of 3 = 380/1.732 = 219.3995 v The calculation is pretty much the same, so the wire current is equal to the current.
Q:What is the classification of ac motor?
According to the principle, the ac motor can be divided into two categories, synchronous motor and asynchronous motor, synchronous motor rotation speed and the frequency of the ac power source has a strict corresponding relation, in the running speed strictly keep constant; The speed of the asynchronous motor changes slightly as the load changes.
Q:Ac motor speed control method
You can change the frequency, you can change the logarithm of the magnetic pole, and you can change the difference in three ways
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:Is the brushless dc motor a synchronous motor or asynchronous machine? Thank you very much!
The principle of brushless dc motor is different from that of ordinary induction motor, which cannot be separated by synchronous or asynchronous. The so-called synchronous and asynchronous means that the rotor and air gap in the rotor and air gap hold the same rotational speed while the motor is running.
Q:Does ac motor control circuit have to be communicated?
When coil by current, under the action of permanent magnets, turn through the attraction and repulsion, when it turn to balance and magnet, the original through the electric line is corresponding with electric contact patches on the commutator I leave, and brush connected to the group that accord with steam coil corresponding contact, so keep repeating, dc motor turns up
Q:The difference between dc brushless motor and ac servo motor
Simple dc brushless motor can not do position control and can only do speed control. Ac servo can do position control and other kinds of control.
Q:What is the difference between dc, alternator motor, and how the motor works
At present, the most common generator in the country is a fixed coil, which makes the two magnetic poles rotate so that the inductance current (alternating current) is generated. When you generate electricity, you're cutting it, and you're not cutting it unless you stop working.
Q:The ac motor doesn't have a brush so how does the rotor rotate?
Ac motor rotor CaoGuan cast aluminum strip and at both ends to form closed circuit of the aluminum ring, when the stator magnetic field across the rotor conductor, a conductor is cutting the induced electromotive force resulting from the magnetic field lines and current. The electromagnetic torque of the rotor axis is formed by electromagnetic force, and the rotor is rotated by rotating field.
Q:The converter can control which motors
The converter can be controlled General purpose motor This is used in situations where the accuracy of the torque speed is not high It has good energy saving and automatic control effect on the fan pump Vector control type inverter General motors can also be used to control frequency conversion motors Vector control characteristics have good control over torque load changes and speed above angular velocity A servo controlled converter And it's a lot more complicated to control the variable frequency special motor and to have better control and control over the vector
