Sell high-quality Chinese motor products, and welcome customers to customize their designs. What is the role of motors? The most widely used of various motors is AC asynchronous motors (also known as induction motors). It is easy to use, reliable in operation, low in price, and firm in structure, but it has a low power factor and difficult speed regulation. Synchronous motors are commonly used in power machines with large capacity and low speed (see synchronous motors). The synchronous motor not only has a high power factor, but also its speed has nothing to do with the size of the load, only determined by the grid frequency. Work is more stable.
DC motors are often used in occasions requiring wide-range speed regulation, but they have a commutator, complex structure, expensive, difficult to maintain, and not suitable for harsh environments. After the 1970s, with the development of power electronic technology, the speed control technology of AC motors has gradually matured, and the price of equipment has been decreasing, and it has begun to be applied.
