Embodiment Construction

[0028] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings and specifics. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element, or one or more intervening elements may be present therebetween. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "upper", "lower", "inner", "outer", "vertical", "horizontal", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the referred device or element must...

Abstract

The invention relates to the technical field of motors, and discloses a motor and an electric toy, the motor comprises a stator assembly, a rotor assembly, a front end cover assembly, a rear end cover assembly, a three-phase power line and a data transmission line, the rotor assembly is sleeved in the stator assembly, and the rotor assembly comprises a magnetic ring, a magnetic weaving frame, an iron core, a plurality of magnetic shoes, a rotating shaft and a rotor end plate. Through the structure that the positioning grooves are formed between the adjacent magnetic shoes, the magnetic weaving frame is provided with the positioning bosses, and the positioning bosses are inserted into the positioning grooves, the motor can accurately position and assemble the rotor assembly, so that the magnetic poles of the magnetic rings correspond to the magnetic poles of the magnetic shoes, the positioning precision of the rotor assembly of the motor is improved, and the induction precision of the induction device to the magnetic shoes is improved; the working performance of the motor is improved.

Description

technical field [0001] The present application relates to the technical field of electric motors, in particular to an electric motor and an electric toy. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. The motor includes a rotor and a stator. The motor uses a energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation. torque. The brushless induction motor is one of the motors. The brushless induction motor has better low-speed linearity and better starting torque. Therefore, the application scenarios of the brushless induction motor are more extensive. [0003] In the process of implementing this application, the inventor found that there are inductive components inside the brushless induction motor to sense the position of the rotor, and to commutate power supply to the stator by ou...
