1. The intermediate frequency refers to the frequency of the AC voltage generated by the inverter after the DC voltage of the power supply is rectified and filtered in the inverter. 2. Frequency converter is a device used to control the speed of the motor, which adjusts the speed of the motor by changing the frequency of the power supply voltage.
Intermediate frequency is a key parameter in the working process of the inverter, which determines the running state and performance of the motor. 3. The choice of intermediate frequency is related to the rated speed and load characteristics of the motor.
A higher intermediate frequency can improve the speed response of the motor, but it will also increase the loss and noise of the motor. The lower intermediate frequency can reduce the loss and noise of the motor, but it may affect the speed adjustment range and accuracy of the motor. Therefore, when selecting the intermediate frequency, it is necessary to consider the requirements of the motor and the actual application scenario comprehensively to achieve the best operating effect.
Frequency converter intermediate frequency refers to the output frequency obtained after the input power frequency is converted by the circuit inside the frequency converter during the operation of the frequency converter. It is an intermediate step for the converter to convert the input power frequency to the desired output frequency. The selection and adjustment of the intermediate frequency can be achieved through the control system of the inverter to meet different application requirements. The stability and accuracy of the intermediate frequency have an important impact on the performance and working effect of the inverter, so it is necessary to pay attention to the selection and adjustment of the intermediate frequency when designing and using the inverter.
