Motor frequency converter power frequency-variable frequency switching circuit
Source: InternetPublisher:newlandmark Keywords: Frequency converter motor power frequency switching circuit Updated: 2020/04/30
A simple motor frequency/variable frequency switching circuit is shown in the figure. In the figure, SA is the power frequency /variable frequency switch,
SBi is the start button, and SB.l is the stop button. The functions of each terminal are the same
The analog voltage input (frequency given), analog current input and other circuits are not shown in the figure.
