  • Method and device for starting motors in weak grids
    Patent number: 9425713
    Abstract: Method and device for starting a motor (12) in weak grids, especially asynchronous motors, which motor after start-up is supplied by a supply grid (13). The device (11) includes a frequency converter (14), which is rated in relation to the size of the motor (12) and arranged to bring the motor (12) up in speed, arranged to synchronize output voltage with voltage from the supply grid (13), and arranged for connecting the motor (12) to the supply grid (13) after the voltage of the motor is synchronized with the voltage of the supply grid (13). The main object is to do this with as low costs as possible and in the most space-saving manner.
