Problems solved by technology
[0003] In the current assembly process of the inner rotor motor, the permanent magnets are fixed on the rotor body by means of tools and gluing. However, it takes time for the glue to harden, and the tools will remove the permanent magnets after they are positioned on the rotor body. Before curing, the permanent magnet may be displaced due to removal of the tool, or due to environmental vibration, or other factors, resulting in inconsistent spacing between the permanent magnets, making the permanent magnets and The magnetic field between the stator coils is not uniform, so that the deflection of the rotor is too large when it rotates, and the bearing will also bear high impact force due to vibration. When it runs for a long time, it is easy to cause damage to the motor.
In addition, if the rotating shaft and the rotor are not insulated, the internal mechanism of the motor will form a current loop. Therefore, when the motor is running, the rotating shaft will easily generate current, which will damage the bearing and cause the motor to operate poorly and eventually lead to failure.

Description
technical field [0001] The present invention relates to a motor. Background technique [0002] Motor is a device that converts electrical energy into mechanical energy, and has been widely used in daily life products, such as air conditioners, fans, washing machines, water pumps, disk drives, electric razors, etc. Although there are many types of motors, the principle of their main application is still the electromagnetic effect. Generally speaking, motors have structures such as rotor magnets and stator coils, and are classified into two categories: outer rotor motors and inner rotor motors according to their arrangement. Taking the inner rotor motor as an example, the magnetic field generated when the current enters the stator coil interacts with the magnetic field of the permanent magnet of the rotor, which can make the shaft rotate and perform work. [0003] In the current assembly process of the inner rotor motor, the permanent magnets are fixed on the rotor body by m...
