Stator circuit series resistance voltage reduction start button control circuit

(1) Stator circuit series resistance step-down start button control circuit
    The circuit is shown in Figure 3-32. When starting, press the start button SBi, a resistor (or reactor) is connected in series to the stator circuit
, and the resistor (or reactor) is used to divide the voltage to achieve the purpose of starting with reduced voltage. After starting, press button SBz, the series resistor
(or reactor) is short-circuited, and the motor is connected to full voltage and enters normal operation.
