As the use of inverters is becoming more and more widespread, some customers can report that the inverter frequency cannot be adjusted up. If the company does not solve the hardware problem, it is likely that the inverter load management ability is not good, that is, the output can be carried. The maximum torque is less than the torque caused by the load lifting.Explosion proofMotorA type of motor that can be used in flammable and explosive plants, and it does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.So the following is the main reason for the analysis of the following main reasons for us and the high-efficiency motor technicians:
(XNUMX) The V/F ratio is too large
Some of these are also called torque boost converters. If the parameter is set large, sometimes it will not start normally, and the corresponding reduction will solve the problem;
(XNUMX) The acceleration time is too short
In theory, the longer the accelerating development time, the stronger the capacity that can be improved with load. If an accelerating working time is set to be too short, some inverters will display overcurrent or information overload and overheat warning lights, but some of our companies will not display them. It is designed, but it is stuck in a certain frequency range.
(XNUMX) Hardware problems
The problem of the inverter transformer can not measure the correct current normally, and similar situations may occur, except for the aging of a measuring element of the main board, which is often encountered when maintaining the inverter.
