Q:Speed of 3000 r / min three-phase motor how to change its speed
The key lies in two points: 1, you ask the variable range is how much? 2, your motor had a few qualifying? If your motor is 6 outlet, and you only need to speed, plus your motor is also an asynchronous motor, and you do not have the requirements of the load; then congratulations, you can achieve "speed" You just put the motor wiring way to do a △ - Y or Y - △ conversion can be achieved. If the above conditions you have one or two can not meet, then your best way is to buy a drive to achieve the variable speed. Of course, you can also make some changes to the winding to achieve the so-called single-winding multi-speed operation (this change, but the need for a certain technical content).
Q:Can the four motors be tuned to 2900 rpm?
You have to look at what is the load, and look at the motor bearing can not bear 2900 turn, if the line, then under normal circumstances are possible. Only to the speed up to the motor rated speed above, the motor output torque is reduced.
Q:Do you need to rectify before switching?
Need to rectify. The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
Q:What is the difference between AC and DC frequency converters?
Inverter air conditioner is relatively speaking in terms of ordinary air conditioning, ordinary air conditioning compression motor using AC induction motor, speed unchanged, 50HZ when the speed is about 2880r / min. The inverter air conditioner is the first 220V, 50HZ single-phase AC into three-phase inverter AC (25 ~ 118HZ, 56 ~ 160), the supply of compressors, through the frequency changes to adjust the compressor speed, so that continuous cooling capacity to adapt to air conditioning Load needs. L inverter air conditioner works: inverter air conditioner compressor by the variable frequency motor drag, the power inverter output frequency changes in the alternating current to the motor, so that the motor speed can be based on the needs of indoor cooling and continuous change, the final compressor cooling capacity To achieve continuous changes in the automatic control. In order to meet the continuous changes in the cooling capacity, the refrigeration system uses an electronic expansion valve, the pulse motor switch valve core, rapid control into the evaporator refrigerant flow. Power frequency changes from the inverter to achieve, as shown in Figure 1: 220V, 50HZ of the mains input, the frequency converter A / D AC / DC conversion, D / A inverter, the output frequency required by the three-phase alternating current, Room switching power supply principle is similar.
Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
It depends on what type of equipment you use, the average energy-saving fan pumps, about 25-40 between; generic class is based on the frequency you use to decide, according to the frequency you use with 50 Hz Compared to energy saving.
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
The synchronous speed of the motor is n = 60f / p P is the pole pair number, and f is the power supply frequency. The pole pair number of the 6 pole motor is 3. Therefore, f = n * p / 60 = 8000 * 3/60 = 400Hz.
Q:Computer frequency changer to do cd frequency changer how points positive and negative
This inverter is 380V of the bar, the capacitor series is to increase the pressure, and then parallel to increase the capacity of the capacity of the capacitor and the inverter is proportional to the power, the greater the capacity of the capacitor capacity requirements are greater.
