Note:
In order to prevent electric shock, the motor and frequency converter must be
grounded before use.
• Do not install the incoming capacitor or surge suppressor, radio noise filter
to the output of the frequency converter. This will lead to the failure of the
frequency converter or the damage of the capacitor and surge suppressor. If any
of the above equipment has been installed, please remove it immediately. When
it is necessary to set a non fuse circuit breaker at the output end, please
consult the manufacturer for the selection of non fuse circuit breaker.
• With regard to electromagnetic wave interference, the input / output (main
circuit) of the frequency converter contains high-frequency components, which
may interfere with the communication equipment near the frequency converter
(such as AM radio). Therefore, EMC filters are installed to minimize
interference.
• For details of peripheral devices, please refer to the user manual of each
option and peripheral device.
• PM motor cannot operate on power frequency power supply.
• Because PM motor is a motor with built-in permanent magnet, even when the
power supply of frequency converter is disconnected, as long as the motor is
still rotating, high voltage will be generated at the motor terminal. When the
output switch is closed, turn on the power supply of the frequency converter
and use it when the motor is stopped.
- Q:Who knows how the inverter is calculated?
- There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
- Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
- Can be installed by a simple float level control to achieve, the general frequency is to constant pressure, of course, start and stop is completely controlable Oh. It's good for the pump to start the speed change
- Q:HP laptop power adapter how to open
- That thing is not generally no screws, is sticky together. If you want to split, can only use the blade along the seam a little bit of open
- Q:What is the difference between variable frequency motor and variable speed motor?
- The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
- Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
- Or the star of the three-phase motor to the corner, so that after the rectifier inverter into a 220-volt three-phase AC ...
- Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
- Change 6 will only be slower, the fan is no longer role. The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.
- Q:Pump frequency converter instantaneous restart and restart the problem
- Speed tracking start, with them better. Speed search time is less than the free downtime, not too small too much, will be over-voltage protection. I do not understand and contact me. Your inverter voltage level, manufacturers.
- Q:Is the inverter output current proportional to the output torque?
- When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload
- Q:Laptop power adapter is broken, which brand is better domestic
- This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
- Q:What is the difference between AC and DC frequency converters?
- L inverter air conditioner refrigeration system components: inverter air conditioner by the compressor, evaporator, condenser, electromagnetic four-way valve, electronic expansion valve, defrost valve, double capillary and other components (see Figure II), work, air conditioner Room needs, automatic control of the inverter output frequency higher AC, the motor speed to speed up, the compressor cooling capacity increased to achieve the purpose of rapid cooling or heating, on the contrary, when the room cooling or heating less, Compressor to normal speed or lower speed operation, therefore, inverter air conditioner has a continuous cooling capacity adjustment, making the room temperature fluctuations smaller. In the process of compressor operation, the microcomputer system controls the inverter compressor at the same time, controls the opening degree of the electronic expansion valve, maintains the proper refrigerant flow, and directly changes the flow of the refrigerant in the evaporator to change its state, the compressor The speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the supply amount of the expansion valve, so that the degree of superheat is not so large that the capacity of the evaporator is maximized, so that the refrigeration system The most efficient control.
