Q:Can the voltage regulating module be used as AC motor speed regulation?
Want to control motor speed, only changing voltage frequency on the stator can (with more of a V/F control, change the frequency corresponding to the change of voltage amplitude), change the voltage regulator will not only change the frequency, voltage, it will only change the motor torque (the size of the voltage will not change, otherwise it will cause the stator coil current is too large; for example, if you burn the motor) with voltage regulator voltage applied to the motor will change the speed two times, will have little change but far less than the two times. When using the voltage regulator experiment, do pay attention to the rated voltage of the motor, otherwise it may cause permanent damage to the motor!
Q:Is the single-phase carbon brush motor a direct current motor or an AC motor?
(1) motor is a DC motor with single-phase brushless motor or AC, there is also some DC motor AC and DC motor, such as most of the pistol electric drill AC and DC motor, AC and DC power can also be used to use.(2) the power supply of rectifier bridge is not from positive and negative pole, and the power supply of rectifier bridge must have positive and negative poles, otherwise it is not power supply of rectifier bridge.(3) bidirectional thyristor should be used in AC circuit. If your motor speed is bidirectional thyristor, it may be AC and DC motor.DC motor carbon brush and AC motor carbon brush is the same, so there are AC and DC dual series motor.
Q:Which is better, alternating current tubular motor and direct current tubular motor?
Good communication.The main difference between AC and DC motors is that the nature of the power supply is different. The AC motor uses alternating current. The generator sends out alternating current, while the direct current motor uses the direct current, and the generator sends out the DC point too
Q:What's the UVW representative of the motor, please?
The UVW of the motor stands for the three terminals, which are 380 volts three-phase alternating current on the three terminals
Q:How to change AC motor to generator?
The triangular line wiring into Xinghang capacitor can then add old but the efficiency is very low capacitance as motor power.
Q:The difference between a direct current motor and an alternating current motor
As the name suggests, the direct current motor uses DC as the power supply. AC motors use alternating current as power source. Structurally, the principle of the direct current motor is relatively simple, but the structure is complex, and it is not easy to maintain.
Q:Soybean milk machine AC motor or DC motor is good?
With a special fragrance, and slightly stimulated; slightly sweet, and accompanied by stimulating spicy taste. Flammable gas whose vapors can form explosive mixtures with air and can be miscible with water at any rate.
Q:Why is Tesla's Model s electric vehicle using AC motor instead of the more popular frequency conversion DC motor?
The structure of DC motor is complex, the cost is relatively high, and later maintenance is troublesome. Larger motors require an external cooling fan. Can be very simple to realize the speed of the economy. Big torque and good mechanical characteristics. The AC motor has the advantages of simple structure, low cost and simple maintenance. You can't speed it yourself. In the past, the frequency conversion was not timely, and the DC motor was used in places requiring good speed control (machine tools, cranes, textiles, etc.). However, with the development of frequency conversion, the performance of vector frequency conversion + frequency conversion motor is close to that of DC motor.
Q:The difference between DC motor and AC motor in electric stacker
Advantages of AC motor1. AC motors are cheaper to manufacture.The development of 2. vector frequency conversion technology can be simulated by frequency conversion motor into direct current3. with respect to the DC motor has enough advantages in simple structure, easy maintenance, low requirement to the environment and energy saving and improve productivity and so on, the AC speed control has been widely used in industrial and agricultural production, transportation, national defense and daily life.
Q:Why do motors need capacitance when they start?
Only single-phase AC motors use capacitor, DC motor and three-phase AC motor are not needed.The two phase motor coil can not generate a rotating magnetic field, which must be in a coil on series capacitor, the current current branch ahead of another coil, in order to form a rotating magnetic field between the two coils, the rotation of the rotor.
