Q: 3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A: Probably the error of the clamp meter. 4 more current is correct.

Q: Is it possible to use a different laptop's power adapter?: For the power adapter, whether access to equipment, the following aspects of the measurement standards: Interface form The interface plug and socket used must be dimensioned. Voltage size The output voltage of the adapter is the same as the required voltage of the connected device (eg notebook). Inconsistencies may not be able to start or burn the device properly. Current or power The power of the adapter is greater than the maximum power required by the device. Power is not enough, may cause the voltage to drop, the adapter is hot, or burn the adapter. More than the above, the use of more power of the power adapter, while meeting the interface and voltage conditions, it can be replaced.

Q: Laptop power adapter is broken, which brand is better domestic: What brand of your laptop brand? It is best to be original,

Q: What is the motor series parameter setting of the inverter? If it is with the spindle,: Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning

Q: Will the motor suddenly stop when the inverter is suddenly powered down?: but there are exceptions, such as head pump, water hammer effect after power failure will make the motor Reversal

Q: What is the characteristic of the variable pole speed method?: Edit this paragraph speed method First, variable pole alignment speed method This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.

Q: What is the frequency converter used to do, why some motor with the inverter?: Speed control, there are speed requirements of the place are in the inverter

Q: Can the inverter be used to control the speed of the DC motor?: For the brush commutation DC motor, the speed of the output torque in a certain circumstances and the input voltage related. For this type of motor, use the inverter to control the output of the rectifier device that supplies power to the motor, which can control the speed. For the brushless DC motor, the controller is in accordance with a certain law to change the form of stator winding power supply to produce a rotating magnetic field to drive the rotor rotation. That is, the DC motor controller outside the part of the AC motor and the structure and the principle has not much difference (see below. For such motors, with the inverter to replace the controller, and control the same as the AC motor Control the speed.

Q: Variable frequency conversion frequency difference characteristics based on,: Pole is the pole pair. So that the synchronous speed has changed, you can speed, but can not smooth speed.

Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together: Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
