In a WeChat chat with many colleagues in the industry, a question came up: Is it too late for an electrician in his forties to learn to repair electric motors? Is it easy to learn how to repair electric motors? Are the prospects good? Because I have been working on the front line for a long time and have been exposed to many aspects of the electrical industry, I will answer your friends’ questions from several aspects below.

First of all, for electrician friends in their forties, I do not recommend learning to repair electric motors. First of all, motor maintenance is a real technology, which can also be said to be an art activity. It is not an easy thing to master proficiently, from sampling wire mold - winding coil - slot insulation - embedded wire - End shaping - phase insulation - binding - painting - assembly. Each process must be done just right, otherwise it will affect the next process. For example, if the sampling wire mold is small, it will be difficult to embed wires. If the sampling wire mold is large, the end of the motor will be too big, which will waste copper material and easily cause the shell to hit during assembly. Among these links, the most critical one is wiring. The quality of wiring is directly related to the quality and efficiency of motor maintenance. Wiring is all hands-on work, and there are many skills in it. This is learned slowly, and you must operate both by yourself. Only with more than 300 motors can you have a feel, master the operating skills, and achieve proficient operation.

Secondly, motor maintenance is both technical and physical work. Assembling large motors is very laborious, and motor wiring is also tiring. Friends who maintain motors for a long time usually have an occupational disease - back pain. My electrician friend in his forties, as he gets older, his eyesight and hands can no longer keep up, the learning cycle is long, and his physical strength is getting weaker day by day. When you become proficient, you won't be able to do it anymore.

You just learned how to repair electric motors. You have to consider whether there is business to do, whether there is a market, and how many motors can be repaired in a year. We spend a lot of effort learning to repair electric motors just to make more money. If there is no electric motor to repair, what is the value of our efforts?

The profit margin for repairing motors is still good. In the current industry, one kilowatt in Danyang, Jiangsu is generally about 60 yuan. Motors below 1 kilowatt are charged at 2 kilowatts. Special motors have special prices, such as servo The motor is 3 kilowatts, and the maintenance fee is generally 600, etc. The maintenance fee for special motors varies.

A friend in his forties dreams of learning electric motors and starting a repair and maintenance business in a city with developed industries. I personally think it is unrealistic. It is not a dream to go it alone in an industrial zone and conquer the world. Easy things. First, your skills must be excellent, because there are all kinds of electric motors in industrial areas. Second, you must be able to mess around. If you have good skills and don't know how to mess around, you will repair the motor if it cannot be reached. Third, you must prepare a trailer. To deliver large motors to the factory, you need to have the supporting tools and assistants to repair the large motors, which is not easy.

My friends in their forties, older and younger, are the backbone of the family and have great responsibilities. Can you afford to delay?

The above only represents my personal opinion, and I would like to give some advice to friends who are hesitant in this regard, for reference only.
