introduction：Belt pulley，It belongs to disk hub parts，Generally the relative size is relatively large，The manufacturing process is generally cast、forging-based。Generally, the larger size is designed by casting method，The material is usually cast iron（Casting performance is good），Cast steel is rarely used（The casting property of steel is poor）；Usually smaller in size，Can be designed for forging，Material is steel。The pulley is mainly used for long-distance transmission of power，For example, the power output of small diesel engines，Agricultural vehicle，tractor，CARS，Mining machinery，Machining equipment，Textile machinery，Packaging machinery，lathe，Forging bed，Some small horsepower motorcycle power transmission，Power transmission of agricultural machinery，Air compressor，retarder，Reduction gear，dynamo，Gin and so on。 The advantages of pulley drive are：Pulley drive can ease the load impact；Pulley drive runs smoothly、Low noise、Low vibration；The structure of the pulley drive is simple，Easy to adjust；Pulley drive The manufacturing

introduction：Asynchronous motorin1885It was invented by the Italian physicist and electrical engineer Ferraris。1888years，Submit an experiment report，A rigorous scientific description of the rotating magnetic field is given，Develop asynchronous motors for the future、The self-starting motor laid the foundation。Ferraris believed that his theory of the rotating magnetic field and the new products he had developed were of far greater scientific value than material value，So he chose not to patent his invention，But to demonstrate these new results to the public in the lab。He also advocated the use of alternating current systems。The same year，Nicolai·Tesla has patented induction motors in the United States。A year later，Mikhail Dolivo-DobrovolskyInvention of cage asynchronous motor。The development of asynchronous motors is rapid，For asynchronous motors of the same size，Rated power by1897annual5.5kWRun to1976annual74.6kW。Squirrel cage asynchronous motor is a widely used asynchronous motor。 Principle of asynchronous motor： Afte

introduction：Servo motor，The main difference between it and the variable frequency motor is that it has an encoder，It is then transferred to a servo motor drive，Reuse control theory，Such as gain，Adjust time，Simply put, the servo motor constitutes a closed-loop control system，And it starts fast.，Fast stop，The load capacity is also better than the frequency conversion motor，With these features，And that creates speed，torque，Position three control mode，For more demanding occasions，More applications。 1、The working principle of servo motor and inverter plus ordinary AC motor is basically the same，All are AC DC AC voltage motor drivers，Only the technical index requirements vary greatly，So there is a big difference in motor and drive design。 2、The servo system is mainly used for fast tracking、Super wide speed range、Precise positioning、Applications such as ultra-low speed and large torque，For example, precision CNC machine tools、High speed packaging machine、High-end textile、Packaging and printing machinery and other machinery man
