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.

Page 13: Commissioning
Problems associated with DOL starting The problems caused by DOL starting may be divided into two groups: An abrupt start causes mechanical shock, jolts in the mechanism, shock removal of free play etc. A heavy start cannot be completed. Let us review three variations of a heavy start: 1. -
