Background Art

Motor: Also known as an electric motor (commonly known as a motor), it refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. At present, direct drive technology has been increasingly applied to industry and life. Due to the omission of the transmission device, the system efficiency of direct drive technology has been effectively improved. In related technologies, direct drive technology is mainly used in low-speed and high-torque situations. In order to maximize the motor efficiency in low-speed and high-torque driving situations, the motor needs to increase the outer diameter or axial length as much as possible, the volume of the stator is significantly increased, and the cost of the stator part increases accordingly.

In the prior art, a Chinese patent document with a publication number of CN106374707B is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a motor, comprising: an outer stator, the outer stator comprising at least one outer stator block, the number of the outer stator blocks being less than the number of outer stator blocks required to be connected into a closed ring along the circumference of the motor; an inner stator, the inner stator being located on the inner side of the outer stator in the radial direction of the motor and spaced apart from the outer stator, the inner stator comprising at least one inner stator block, the number of the inner stator blocks being the same as the number of the outer stator blocks; a rotatable rotor, the rotor being a closed ring extending along the circumference of the motor, the rotor being located on the inner side of the outer stator and the outer side of the inner stator in the radial direction of the motor. The motor according to the embodiment of the present invention improves the motor efficiency in low-speed and high-torque driving occasions, and can be applied to household appliances, electric vehicles, wind power generation and other occasions. The motor has a simple structure, high system efficiency, cost saving and a wide range of applications.

In order to solve the problem that the stator volume inside the motor is large and the cost of the stator part increases accordingly, the existing technology adopts a method of arranging inner stator blocks and outer stator blocks on the inner and outer sides of the rotor respectively. However, the motor will generate high temperature after long-term use, which will cause high-temperature operation to affect efficiency and pose certain safety hazards, thereby reducing the service life of the motor.
