Abstract: PURPOSE:To start an induction motor smoothly without using a reduced voltage starting board by a method wherein a generator which has the same capacity as the induction motor is connected to the motor in a non-excited state and the excitation current of the generator is gradually increased to make the generator voltage rise to the level lower than a rated voltage and, after a starting current falls, the generator voltage is gradually increased. CONSTITUTION:A generator 2 which has an approximately same capacity as an induction motor (DM) 3 which is an object to be started and which is directly coupled with a pump 4 is provided. In order to start the DM 3, an excitation current applied to the excitation winding 2A of the generator 2 is gradually increased from zero and the voltage of the generator 2 is made to rise gently to a value, for instance 70% of a rated voltage, which is preset by a voltage setting device 53 and applied to the DM 3. This state is continued for a fixed time, i.e., until the DM 3 is started and a starting current starts falling.
