Motor, also known as motor, is the power source of various electrical appliances or machinery, and its function is to generate driving torque. Motors are often seen in our lives, so how to connect the four wires coming out of the motors? What are the precautions for wiring? Next, Bian Xiao will introduce relevant contents to you. Let's have a look.
How to connect the four wires of the motor?
First, prepare a multimeter, separate the four leads in the motor junction box, and remove the capacitor. Then set the multimeter to the resistance range, measure the primary winding and the secondary winding, then connect one of the blue wire and the red wire, and connect the other two to the two lead-out wires of the capacitor, which can be positive or negative. Finally, connect the zero line of the power supply and the blue line connected in front to the red line, the live wire to one end of the capacitor, and the power ground wire to the motor shell.
What are the precautions for wiring?
1, pay attention to the correct wiring method when installing wires, and try not to have connectors, because connectors will cause relatively large resistance and the wires will easily heat up. If you can't avoid joints when connecting wires, wrap them with insulating tape to avoid accidents.
2. Before installing the wire, make a good plan and choose a reasonable installation form. Wires are divided into two types: exposed and concealed. Exposed installation refers to laying wires on the surface of walls and ceilings, but pay attention to the fact that wires cannot be folded or squeezed when exposed, and need to be fixed with nails. Concealed installation refers to laying wires in the ceiling or wall of the suspended ceiling, which is more beautiful. For the sake of safety when installing wires, you should ask professionals for help.
3. When installing wires, you should use correct grounding wires, especially microwave ovens, refrigerators, air conditioners and other electrical appliances. A three-phase plug is needed. Be sure to install a reliable grounding wire.
Summary of the article: The above is Bian Xiao's introduction on how to connect the four wires of the motor and what matters need attention, hoping to help some friends in need.
