Speed regulation by connecting resistors in series in the excitation circuit
In order to change the main magnetic flux, a speed regulating resistor R is connected in series in the excitation circuit
, as shown in the figure. Changing the size of the speed regulating resistor R can change the excitation current, thereby changing the main magnetic flux, thereby
achieving speed regulation. This method of speed regulation can only reduce the magnetic flux and increase the speed.
