An electrical starter is a device used to start an electrical motor by providing the initial power to overcome inertia.

• Electrical starters are commonly used in various industrial applications to start motors

• They can be manual or automatic

• Examples include direct-on-line starters, star-delta starters, and soft starters

DOL starter directly connects the motor to the power supply, while star delta starter initially starts the motor in star configuration before switching to delta configuration.

• DOL starter provides full voltage to the motor from the start, causing high starting current and torque

• Star delta starter reduces the starting current and torque by initially connecting the motor in star configuration

• DOL starter is simpler and che...read more
