FAQ

1. In the previous article, we talked about the damage of the motor body due to the lack of phase fault of the motor. In most cases, the phase loss problem of the motor is caused by the problem of the power supply, mainly including the power switch and the connection between the power supply and the motor body. The contacts of the contactor are in poor contact, etc. However, there are also some problems that are caused by improper handling of the motor manufacturing process, motor maintenance and maintenance process.
   
   For the motor body, there are two links that are most likely to cause a phase loss fault, one is the connection between the main wire and the lead wire of the motor winding, and the other is the connection between the motor lead wire and the terminal.
   
   For the connection of these two links, different motor manufacturers use different processing techniques, so the severity of the problem is not the same.

    

   When the main wire of the motor winding and the lead wire are connected, due to the large difference in the wire types of the two, if it is not handled properly, especially in the case of solder heating and welding, there are more possibilities for problems, and the quality of the solder will directly affect the final result. In order to avoid this problem, many motor manufacturers use intermediate frequency welding or direct hot-melt welding equipment, which greatly improves the connection quality of this link.

    

   For the connection between the lead wire and the terminal head, most motor manufacturers use cold pressing to solve the problem. In general, this treatment method is very effective, but when the matching mold is not suitable or the pressure is unreasonable, it is very easy to If the connection between the two is loose, or the lead wire conductor is directly crushed, this may lead to connection problems during the operation of the motor, and the motor phase loss problem may occur in extreme conditions.

    

   In order to prevent the adverse effect of the lack of phase on the motor, most equipments are equipped with protective devices in the circuit, which can protect the motor, but the most fundamental measure is to make the quality of the motor solid and ensure the safety of the running circuit .
