Problems solved by technology

The motor in the existing electric toothbrush generally needs to be installed with a spring or a torsion bar similar to a torsion spring. During use, this type of structure is easy to damage and is not easy to repair. When the motor has a better magnetic circuit structure inside, it must have a better Electromagnetic utilization, thereby reducing the load of the motor torsion spring and prolonging the product life

Abstract

The invention discloses a motor suitable for an electric toothbrush. The motor comprises a machine shell, a stator assembly is connected to the inner wall of the machine shell, a rotor assembly is arranged in the stator assembly, the stator assembly comprises a stator and coils, the coils are fixed to the two sides in the stator, the rotor assembly comprises a rotor, second magnetic steel and magnetic steel assemblies, the rotating shaft is sleeved with the rotor, and the outer side of the rotor is connected with the two symmetrical magnetic steel assemblies. The invention further discloses animplementation method of the motor suitable for the electric toothbrush. According to the invention, the first magnetic steel is connected between the two pieces of second magnetic steel, and the three pieces of magnetic steel are arranged in an array, so that a magnetic field generated by the magnetic steel is fully utilized, and the characteristics of the simple structure and the high energy utilization rate are achieved; and the magnetic circuit is balanced, and the rotating shaft in the center of the motor can bear small stress, so that the service life of the rotor assembly is prolonged,and the purpose of prolonging the service life of the motor is achieved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor suitable for electric toothbrushes and a realization method thereof. Background technique [0002] With the advancement of science and technology, people's living standards are gradually improving, and more and more automation equipment is integrated into people's lives. Electric toothbrushes are also widely accepted because of their better cleaning strength. [0003] The essence of electric toothbrush drive is its core component - the motor, and the core content of the motor is its internal magnetic circuit structure. The motor in the existing electric toothbrush generally needs to be installed with a spring or a torsion bar similar to a torsion spring. During use, this type of structure is easy to damage and is not easy to repair. When the motor has a better magnetic circuit structure inside, it must have a better Electromagnetic utilization, thereby reducin...
