When making a homemade motor, half of the enameled wires at both ends are removed to optimize the working principle of the coil. When the coil is wound into a circle, if the enameled wires at both ends are scraped off, when the coil rotates, it will be hindered due to the Ampere force and cannot rotate smoothly in the original direction. Therefore, retaining the enameled wire at one end allows the coil to be driven by ampere force for only half a revolution when it completes one revolution, thereby maintaining stable rotation.

The use of enameled wire involves the production of coils and the cooperation of magnets. The coil is wrapped with enameled wire, and the magnet fixes the coil to form a gap that can rotate freely, and is connected to the central axis of the coil through a brush to provide current. In this way, the electric motor can generate rotational power.

The development strategy of the motor industry is to build its own brand, focus on the high-end market, expand overseas markets, and focus on product quality and service. Especially in the industrial field, electric energy consumption is huge, and as the motor is a key link, efficiency improvement is crucial. Optimizing AC motors through frequency converters or using high-efficiency motors can effectively reduce power consumption in the industrial field. The energy-saving effect of frequency converters can reach more than 30%, and the market potential of high-efficiency motors is gradually being released with policy support.

In general, understanding the role of enameled wire and the operating principle of the motor is crucial to the correct production and use of the motor, which is directly related to energy efficiency and motor performance.
