The motor of the turntable on the hotel dining table keeps turning. Sometimes, we pull the turntable by hand to stop it from turning and the motor will not burn. Why?
The turntable on the hotel dining table keeps turning. Sometimes, we pull the turntable by hand to prevent it from rotating and the motor will not burn. This is because there is a special device. Its principle is to install a resistance switch. When a certain resistance is encountered, the switch opens the circuit and cuts it off. When the resistance disappears, the motor switch is reset and continues to rotate due to the action of the spring. This principle is simple. If you look at the principle, you can modify it according to the resistance level.
