The system efficiency is equal to the product of inverter efficiency and motor efficiency. Only when both work under high efficiency, when the system efficiency is high and frequent work, a large inverter can be selected to use the frequency converter for a long time and safe operation.
After the test.The actual power of the motor is indeed surplus, which can be considered.From the perspective of efficiency, the following points should be noted when selecting the frequency converter power:
When the power value of the frequency converter is equal to the power value of the motor * appropriate, the power of the frequency converter should be as close as possible to the power of the motor, but it should be slightly greater than the power of the motor.
When the motor is a frequent start, braking or overloaded start and the power is less than the motor power, attention should be paid to the instantaneous peak frequency operating at high efficiency value.
When the power rating of the frequency converter is different from the motor power rating, whether the flow will cause the overcurrent protection action
