Description

Technical Field

[0001] The present invention relates to the technical field of axial flux motors, and more specifically to an axial flux motor. Background Art

[0002] Axial flux motors, also known as disc motors or pancake motors, are a special type of motor.

[0003] The operation of the axial flux motor is based on the interaction between permanent magnets and electromagnets. When the coils are energized, they become electromagnets. In the most common axial flux motor design, there are fixed coils and free-spinning permanent magnets. When the coils are energized and become electromagnets, the rotor is attracted to the opposite end poles of the stator (opposite poles attract), generating a tangential force component that causes the rotor to rotate. The position of the rotor is determined by an intelligent electronic controller and sensors, and based on this information, it is decided which coil to energize, thereby achieving continuous rotation of the motor;

[0004] Power density: Axial flux motors generally have high power density, suitable for efficient and compact designs. At the same power, the volume and weight of axial flux motors are only about half of radial flux motors. High torque density: Axial flux motors can also release greater torque at low speeds, while providing greater thrust and higher response speed. Compact structure: The shorter axial length not only enables lightweight and compact designs that were previously unattainable, but also extends battery life and reduces energy costs.

[0005] However, there are some shortcomings in the use of existing axial flux motors, as follows:

[0006] During long-term use, the axial flux motor may have conditions such as coil aging and short circuit. When this happens, the existing axial flux motor needs to spend a lot of maintenance costs to disassemble the axial flux motor and replace the coil so that the axial flux motor can continue to be used. However, since the replacement of the axial flux motor coil requires a lot of time and manpower costs, when the coil has conditions such as aging and short circuit, the motor is usually replaced to solve the problem, which affects the service life and use cost of the axial flux motor.
