The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.
