Common sense of industrial control - what is electrical control

What is electrical control


What is electrical control? The motor is represented by the letter M in the circuit (the old standard is represented by D), and its main function is to generate driving torque. As a power source with electrical appliances or various machinery, the generator is represented by the letter G in the circuit. , whose main function is to convert mechanical energy into electrical energy.
1. What is electrical control? The induction switch can only detect metal objects, so more reports/feedbacks are used. The main function of the soft starter is to reduce the starting current of the motor, reduce the impact on the power grid when starting, and mechanically, reduce Mechanical loss, generally only the motor will use power, because the soft starter will only be used when the motor starts to work, sometimes in order to save costs, multiple single soft starters can be used to control the work of the motor, but the control circuit is more complex Contacts, also known as contacts, are the actuators of electromagnetic appliances, which play the role of connecting and breaking circuits. 5) Cross-conductor connection points for electrical direct connection are indicated by black dots. Dynamic braking is suitable for large-capacity motors that require smooth, accurate braking and frequent starting.
2. What is the electrical control? Reverse contact braking is suitable for small-capacity motors below 10KW that do not frequently start braking. Different parts of the same electrical component cannot be drawn together.
3. What is the electrical control, 4) The contacts of all electrical components are drawn in the open and closed state when there is no power supply and no external force. All electrical components should use the national standard unified graphic symbols and text symbols.
