The present invention relates to a method and apparatus for starting the motor 12, in particular an asynchronous motor which is about the grid (weak grid), the motor receives the electric power supplied by the supply grid (13) after start-up. Device 11 comprises a frequency converter 14, the frequency converter voltage and the synchronization of the motor is rated for the amount of 12, and a motor the output voltage supplied to the grid (13) increases the rate of 12 sikimyeo also after the voltage of the motor are synchronized with the voltage in the supply grid (13) is adapted to connect the motor 12 to the supply grid (13). The main purpose of the present invention also performs this in the most space-saving manner with a low cost as possible.
