A Direct-on-Line (DOL) starter is a type of motor starter that directly connects the motor to the power supply at full voltage.

• DOL starters are used for small motors that do not require soft starting or speed control.

• When the DOL starter is switched on, the motor is connected directly to the power supply at full voltage.

• This can cause a high inrush current, which may lead to voltage dips in the power supply.

• DOL starter...read more

Motor resistance can be measured using a multimeter set to the resistance or ohms setting.

• Set the multimeter to the resistance or ohms setting

• Disconnect the motor from the power source

• Connect the multimeter leads to the motor terminals

• Read the resistance value displayed on the multimeter

• Compare the measured resistance value to the motor's specifications
