Problems solved by technology
[0002] The electronic circuit inside the existing electric motor is complex, the internal heat dissipation of the electric motor is conducted outward through the air, and the heat dissipation efficiency is low. If a high-power electric motor is used, according to Joule’s theorem, the current in the circuit will generate higher heat when the electric motor is in use, and there is It may overheat and burn out the circuit, causing damage to the motor, which is inconvenient to use, and most of the electric energy is converted into heat energy, which cannot be used efficiently
