Three-phase motor current is too high - LS power generation
First, the power supply problem
1. The power supply voltage is too high
When the power supply voltage is too high, the motor back electromotive force, magnetic flux and magnetic flux density all increase. Since the magnitude of the iron loss is proportional to the square of the magnetic flux density, the iron loss increases, resulting in overheating of the core. And the increase in magnetic flux causes ...

The reason for the overload trip of the inverter - LS generates electricity
1. The load is too heavy, the load carried by the motor is too heavy, or in other words, the resistance torque of the production machinery exceeds the additional torque of the motor.
2. Use improper overload, for example, increase the operating frequency of the inverter to the extra frequency of the motor, and the motor is in the extra frequency.

A common fatal form of failure of the terminal block - LS power generation
1. Poor touch
The metal conductor inside the terminal block is the core part of the terminal, which transmits the voltage, current or signal from the external wire or cable to the touch piece corresponding to the connector it matches. Therefore, it is necessary for the touch parts to have excellent structure, stable and reliable touch firmness.

Analysis of heat dissipation problems of inverter - LS power generation
In order to use the inverter correctly, it is necessary to consider that the service life of the VFD decreases exponentially with the increase in temperature. This is due to: When the ambient temperature rises by 10 degrees, the service life of the VFD is halved. So pay attention to heat dissipation! When the VFD is working, the current flowing through the VFD is very large, and the VFD emits ...
