Description

Technical Field

[0001] The present invention relates to the technical field of axial flux motors, and in particular to an oil-water composite cooling type axial flux motor and a use method thereof. Background Art

[0002] The axial flux motor is a highly efficient and compact motor characterized by a different direction of magnetic field from the conventional radial flux motor. The principle of the axial flux motor is based on the interaction between magnetic field and current to generate torque. Its unique feature is that the magnetic flux passes through the motor in the axial direction, rather than in the radial direction as in conventional motors. This type of motor usually has a flat appearance with the rotor located on the side of the stator. The axial flux motor has a series of advantages, including high torque density, high power density, compact structure, small size and light weight. These characteristics make it particularly suitable for applications with limited installation space or high performance requirements, such as new energy vehicles and other mobile electric equipment. The axial flux motor is designed for a variety of application scenarios, especially in the field of electric vehicles. It helps to improve the design flexibility and efficiency of the powertrain, and is also suitable for other occasions that require high performance and compact design. Due to its unique structural and performance advantages, the axial flux motor has shown a wide range of application prospects in modern electric vehicles and other high-performance applications.

[0003] At present, most axial flux motors are cooled by adding cooling water channels on the casing and injecting circulating coolant to dissipate the heat of the stator components in contact with the casing. However, this cooling method can only dissipate heat and cool the parts in contact with the casing, while the winding coils of the motor are the main heat source. This makes it impossible to directly dissipate the heat of the winding coils, resulting in poor overall heat dissipation of the motor. Therefore, it is necessary to design an oil-water composite cooling axial flux motor and a method of using the same. Summary of the invention

[0004] The main purpose of the present invention is to solve the problem that the current cooling method of axial flux motors is mostly to add cooling water channels on the casing and dissipate heat to the stator components in contact with the casing by injecting circulating coolant, but this heat dissipation method can only dissipate heat and cool the place in contact with the casing, and the winding coil of the motor is the main heat source, which makes it impossible to directly dissipate the heat of the winding coil, resulting in a relatively poor overall heat dissipation effect of the motor; the present invention provides an oil-water composite cooling axial flux motor and a method for using it, which realizes the function of rapid assembly and molding, facilitates the production and overhaul and maintenance of the axial flux motor, and also realizes the function of simultaneous contact cooling of the fixed end casing body and the output end casing body, and also realizes the function of independent immersion secondary cooling of the inside of the motor, thereby improving the heat dissipation effect of the motor and extending the service life of the motor.
