Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] One of the core concepts of the embodiments of the present invention is that there is an air gap between the first component and the second component, and the plane where the contour of the outer surface of the second component is located intersects the axis of the second component, so that when the first When the component and the second component move relative to each other in the direction of the axis, the length of the air gap changes immediately, thereby providing a motor with adjustable air gap. By adjusting the length of the air gap of the motor, the working characteristics of the motor are changed, so that It is more suitable for the needs of the current working conditions.

[0035] refer to figure 1 , shows a topo...

Abstract

The embodiment of the invention provides a motor, a motor control method, a vehicle and a medium. The motor comprises a first assembly and a second assembly which can rotate relatively. The first assembly is provided with an inner cavity structure, and the second assembly is located in the inner cavity structure; the inner surface of the first assembly is parallel to the outer surface of the second assembly to form an air gap; the plane where the outline of the outer surface of the second assembly is located intersects with the axis of the second assembly; and when the first assembly and the second assembly move relatively in the axis direction, the length of the air gap corresponds to the relative position between the first assembly and the second assembly. According to the air gap adjustable motor provided by the embodiment of the invention, the working characteristics of the motor are changed by adjusting the air gap length of the motor so that the motor is more adaptive to a current working condition requirement.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a motor, a motor control method, a vehicle and a medium. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. [0003] Rotating motor is a kind of motor. A rotating electrical machine generally includes a rotor and a stator, and there is an air gap of a certain length between the rotor and the stator. [0004] The air gap length of the motor is closely related to the output torque and efficiency. Generally speaking, the smaller the air gap length, the stronger the magnetic field, and the greater the output torque of the motor, that is, the motor can output a greater torque when the volume remains the same. However, a stronger magnetic field means greater iron loss in the motor. The motor loss mainly includes two parts: copper loss and iron loss. For driving motors, ...
