Inverter is a kind of speed regulating device, where to use the motor speed regulation, especially asynchronous motor speed regulation, will use the inverter, now mainly in the industrial equipment has been used on a large scale, because the motor is the heart of the industry, and the three-phase asynchronous motor occupies the vast majority of the share, so the inverter is used more, and with the improvement of the day, the inverter is also used a lot in the day.
1. On the fan, it can be used to control the size of the air volume, such as the boiler blower fan and the workshop fan, the fresh air fan and the exhaust fan of the central air conditioner, which can adjust the wind speed according to the incineration situation or other needs, and play the effect of controlling the size of the valve supplying air volume.
2. Water pump occupation, industrial circulating water, daily inverter constant pressure water supply, sewage treatment, and the same reason that inverters will also be used in the transportation of some chemical liquid materials, which are also used to control the flow rate or pressure of some liquids. The same as the fan control, the precision of the inverter is not high, and the special fan pump inverter is used to meet the requirements at a relatively low price.
3. Some transmission categories are used to control the transmission, such as conveyor belts and transmission rollers, and the transmission speed of the material needs to be controlled, so as to achieve the synchronization effect of the whole production line.
4. Mixing, mixing, grinding, crushing, kneading, and some calendering occasions, the need for equipment to "bite" with each other, so that the material is abundantly mixed, this processing process also needs to control the process, the need to use the inverter to complete, and the general general type can also meet the requirements.
5. Suspension, winch, rewinding and unwinding and other occasions, the inverter is required to complete the certain synchronization and tension control, and the accuracy requirements are relatively high, and the vector inverter or direct torque control type inverter is required.
6. Air conditioning compressors and air compressors are often used in situations such as synchronous motors, and the control algorithm is similar to the asynchronous actual frequency conversion speed regulation, only due to the motor, the power is relatively high.
7. Automobile and motorcycle tram occupations, from trains, to electric vehicles, three-wheeled electric vehicles and two-wheeled battery cars, and transportation vehicles, now have inverters in use.
8. Processing occupations, robots and other occasions, the inverter can be used as a spindle or an important rotary table motor, if the servo is also regarded as a special inverter, each axis is used in it.
