The cause of inverter heating - Delta inverter
1. The problem of the inverter and the motor itself
If the motor has been used for a long time, it is not good to clean the insulation function, or the bearing may be stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced, the fixtures of the motor are loose, etc.

When the Delta inverter is powered on, the uptube drive voltage is established
One is hardware, similar to the CPU reset circuit, which gives the downtube a short high-level drive pulse during the initial power-up, and then the voltage drops to 0 to cut off the downtube.
The second is the software, when the CPU is operating normally, it outputs a square wave pulse that only needs to be turned on by the lower three tubes, so that the upper tube ...

Excessive inverter capacity poses a hazard to electrical equipment – Delta
(1) The harmonic current will directly cause the additional heating of the motor, so that the stator of the motor will exceed the rated temperature rise of the motor itself, so that the rated output capacity of the motor will be greatly reduced.
(2) The current wave output of the inverter ...

The benefits of using an inverter – Delta inverter
1. Speed regulation of general motor: By changing the input voltage and frequency of the three-phase asynchronous motor, its speed can be controlled. Generally, when the motor is at low speed, the temperature rise becomes larger due to the decrease in the power of the cooling fan, and the motor load should be reduced according to the frequency.

Introduction to the basic application of Delta inverter
Generally, household appliances use a single-phase asynchronous motor, which relies on capacitance or resistance to split the phase. Motors are often in a short-term repetitive state (on/off) during operation, such as air conditioners, refrigerators, etc. This will inevitably lead to frequent starting, high noise, short motor life, poor temperature stability and energy consumption.

The principle of Delta's inverter inverter
As far as I know, since the advent of active induction motors, there has been a variable frequency operation in the way of communicating generators. Change the rotational speed of the generator, and change its output frequency. Before the advent of high-speed transistors, this was one of the main ways to change the speed of the motor, but due to the decrease in the speed of the generator ...

The output of the inverter is not short-connected to the power frequency
1. To switch the motor of the power frequency, the parking method is set to free parking, and it is important not to park softly
2. Intercept the contactor of the motor from the output end of the inverter, and the control stop button and the inverter parking button are the same composite button, that is, when the inverter is pressed, the inverter parking will be followed by the contactor line.
