Advantages , Disadvantages and Applications
The Advantages , Disadvantages and Applications of DOL Starter are mentioned below:
Advantages
- Simple to design and maintain
- Economical and cheapest starter
- Gives full starting torque at starting
- Troubleshooting and understanding is easier.
- Connects the delta winding of the motor
Disadvantages
- The starter is mechanically tough to operate
- High starting current
- High starting torque
- Reduces lifespan of machine because of mechanical stress
- No control over high starting torque and current
- Voltage dip in power mains
Applications
- Used for the operation of motor which have lower power rating
- DOL starter are used in fans, compressors and small water pumps.
- Used where winding of the motor does not get damaged
DOL Starter
For cases to avoid damage to the motor, various techniques are used to reduce the starting current with the use of a motor starter, these techniques vary on different factors and also protect the motor from overcurrent and overloading. DOL starter is one of the techniques used and in this article, we are going to discuss DOL starters and the starting of induction motors. We will cover what is starting induction motors and their functions, what are DOL starters, their application, terminologies, theory, construction, working, and the difference between DOL and star-delta starters.
