Typical starting methods:
Direct On Line (DOL)
Star-Delta
Autotransformer (ATS)
Electronic Soft Starters
Electronic Frequency Drives (VFD)
What is the optimum starting method for marine application ?
Starting Large Motors on board ships
7
Motor Current
Inrush current 300-800% In
Motor Torque
Initial Torque 150-180% Tn
Direct On Line Starting results in High Inrush Current & Mechanical Shock
The high inrush current can result in voltage drops
The high mechanical shock can result in damage to the motor, load and
transmission system (gear, belt, etc.). It can also require frequent
maintenance.
Direct On Line Starting (DOL)

Two steps starting: Y connected (58% Un), transfer to Delta (100% Un)

Transferpoint
• Transfer to Delta by timer - open loop control, which may result in very high inrush current if transfer is done before motor reached close to full speed
• Step angle of 30°

Summary:
• When starting current must be reduced to avoid voltage drops, due to
the low ratio between motor / Generator power.
• When starting torque must be reduced (mechanical problems)
• When starting complicated mechanical loads
• When starting sensitive loads
• When starting high inertia loads (long starting time)
• For frequent starting
• Preventing over pressure and hammer effect in pump applications
When To Use Soft Starters
