Q: In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Probably the wider range of frequency converter applications! There is a more comprehensive protection of the motor on the inverter
Q: Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.
Q: What is the working principle of high voltage electrodes and frequency converters?
The general high and low methods are used in low-power high-voltage motor to do with energy-saving energy. Low-high-mode high-voltage inverter is controlled by a low-voltage inverter, the voltage directly to the motor with a step-up transformer voltage. Low-high mode is also used in low-power high-voltage motor to do with energy-saving energy.
Q: What is the adapter?
An adapter is a physical device that allows a hardware or electronic interface to interface with another hardware or electronic interface (adapt and without any loss).
Q: The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
The speed displayed on the display may be the speed of the deceleration or transmission. It is also possible that your inverter parameter ratio is not set, you need to modify and adjust, you want to help.
Q: Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
The current amperage of the power adapter is only experienced at its maximum output power, as long as the power adapter output voltage and your original no problem. For example, when the home circuit from the power supply into the terminal does not limit the size of the current, but to provide a fixed voltage. The more your household appliances, the greater the current through the power supply into your home. And the indoor air break switch is a current limit, this is based on the ability to accept the wire. From the point of view of the meter, you use the power equal to UIt = W, where UI is the voltage and current, two multiplication is equal to power, power multiplied by time equal to power consumption. Say back to your power adapter, the power adapter output voltage is rated, as long as this notebook with your original output voltage is the same as your notebook will not hurt. And the power adapter current is the maximum output, the consciousness is the power adapter output maximum power P will not exceed this value, usually 65W or 90W. Greater than the power of such a computer can not be stable operation. Or a physical point of view, the use of notebook power adapter, in fact, the internal is a number of parallel circuits, secondary knowledge tells us the voltage of the parallel circuit at any end are the same size, and parallel devices, the greater the total current in the circuit The
Q: Three-phase two-pole motor can be used to reduce the frequency of the inverter
If you need to be very slow, you can match a four-level motor ah, even more slowly with a reducer
Q: How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together
Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules
