As early as 100 years before the first 100 hours of the metric elements, the Chinese model of a water turbine, namely a water wheel, appears, and is used for lifting and filling and driving grain processing equipment. Modern water turbines are mostly installed in hydropower stations to drive generators for generating electricity.

At present, a water turbine and a cooling tower in the industrial aspect drive the water turbine to drive a fan to rotate by using residual pressure of circulating water, but at present, in a lot of high-energy-consumption enterprises such as steel, chemical industry and the like, the return water pressure of the circulating water cannot completely meet the requirement that the water turbine is transformed by the cooling tower to replace a motor, the forced transformation can not only lead the water outlet temperature of the circulating water to be too high, but also cause irrecoverable loss to enterprises with higher product requirements, and simultaneously cause huge waste of resources, thereby increasing a considerable part of production cost for the enterprises.

And in order to keep the rotating speed of the water turbine within a certain range, the auxiliary motor is used for assisting the cooling tower, and when the rotating speed of the water turbine is weakened, the auxiliary motor can lift the rotating speed of the water turbine, so that the speed of the water turbine is ensured. Most of auxiliary motors and water turbines on the market are directly connected by using gears or belts, and when the auxiliary motor does not need to operate, the inside rotor is used for connecting the belts and the gears and is forced to rotate, so that the auxiliary motor rotates for twenty four hours, and the inside parts of the auxiliary motor are worn to a certain extent, so that the service life of the auxiliary motor is influenced.
