A motor starting reactor is a reduced voltage starting method that reduces terminal voltage of an induction motor when starting it. This method is to drive a motor with direct line by short-circuiting a reactor when complete starting is made (after t seconds) with terminal voltage rising as current is reduced while a motor starts from complete stop.
This facilitates starting a motor by limiting starting current and prevents accidents by other power equipments such as error of instruments.
