	Use and maintenance of electric motors - Delta motors The motor can be started after the work is completed before use, and attention should be paid to the investigation of the motor, transmission device, production machinery and line voltage and ammeter, if there is an abnormal phenomenon, it should be stopped immediately, the fault should be identified and swept away, and then it can be closed and started again. When the motor is running, ...
	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 ...
	Factors affecting Delta's inverter motors and countermeasures 1. The influence of leakage current on the motor and countermeasures If the wiring length is very long, the stray capacitance between the wires will increase, resulting in leakage current. It will initiate overcurrent maintenance, increase leakage current or not ensure the correctness of the current display. The bad situation is that the inverter will ...
	Inverter power-on panel without display fault analysis - Delta In the inverter problem, it is often encountered that the energized panel does not appear. Generally speaking, the problem of the inverter panel not showing up is usually caused by three parts, one is the poor contact of the contactor, the second is the control panel of the inverter, and the third is the damage of the power module that supplies power to the control panel.
	The inverter needs to prepare the braking resistance condition - Delta The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to prevent the capacitor voltage from being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and prevent energy waste. However, the capacitance of the capacitor is ...
	Inverter technology is a motor control method – Delta When you are using the motor, if you simply change the frequency, your motor will most likely be burned out. This problem is especially acute when the frequency is reduced. In order to prevent the motor from burning out, the inverter must change the voltage at the same time as the frequency. ...
