Problems solved by technology

[0003] With the development of consumer electronics, the requirements for the vibration effect of the acoustic wave motor are getting higher and higher. The existing technology of the acoustic wave motor only has a pair of plates, and the torque generated by the work is small, which is increasingly unable to meet the requirements of customers.

Abstract

The invention discloses a novel sound wave motor, which comprises a casing, wherein a stator assembly is arranged on the inner wall of the casing, a rotor assembly is arranged in the stator assembly,one side of the casing is connected with an end cover, the rotor assembly is rotatably connected with the end cover and the casing, the stator assembly comprises a stator iron core, coils and windingcores, the stator iron core is connected to the inner wall of the casing, the stator iron core is of a hollow cylinder structure, the three winding cores are arranged on the inner wall of the stator iron core at equal intervals, the coils are wound on the winding cores, and the three coils are connected in parallel. The invention further discloses an implementation method of the novel sound wave motor. According to the invention, the internal space of the casing is fully utilized, and the three coils are arranged in the casing and are connected in parallel, so that a strong electric field canbe generated when the coils are electrified so as to increase the torque; and the three magnetic steels are arranged on the rotor iron core, so that the driving magnetic field is enhanced so as to maximize the torque.

Description

technical field [0001] The invention belongs to the technical field of sound wave motors, and in particular relates to a novel sound wave motor and its realization method. Background technique [0002] Acoustic motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque, which can be used as a power source for electrical appliances or various machines, such as the motor core of an electric toothbrush. After the sound wave motor is powered on, under the control of the control circuit, the sound wave motor circulates to generate a high-frequency vibration, which in turn drives the toothbrush head to generate high-frequency vibration. [0003] With the development of consumer electronics, the requirements for the vibration effect of the sound wave motor are getting higher and higher. The sound wave motor in the prior art only has a pair of plates, and the ...
