All coil layers of the stator are combined in a ring shape in the hot pressing mode by the adoption of the plastic composites, and the composites contain the magnetic powder, are magnetically conductive only when coils are electrified and are good in insulation performance. Magnetic flux leakage is avoided, impedance of a magnetic circuit is small, the magnet conductivity is high, and therefore the number of turns of the coils can be substantially reduced, and the use number of copper wires is reduced. Compared with a traditional brushless permanent magnet motor, the high-power motor has the advantages that under the same power condition, the total number of the turns is reduced by one third and the use number of magnets is reduced by half; under the same energy consumption condition, the output power of the motor is improved by 15-20%, and the effective power reaches 88%.
