Embodiment Construction

[0024] Reference is now made to various embodiments of the invention, examples of which are shown in the drawings and made apparent from the description of the invention. In the drawings, the same reference numbers in different drawings indicate the same or similar elements whenever possible.

[0025] Embodiments of the present invention provide an alternating current (AC) vibrating motor that, compared with a conventional motor, has the ability to produce the same torque and improve efficiency at approximately the same power consumption with reduced power consumption. higher torque, or both. This increased efficiency can at least be achieved using, for example, strong magnets in the rotor, eliminating asymmetric reluctance, or both. Improved efficiency may also allow embodiments of the invention to operate at lower voltages, such as 20 volts. For safety reasons, it is advantageous to use lower voltages for electric toothbrushes or massage appliances, as these appliances can...

Abstract

An AC motor of axial vibration consists of a rotator with permanent magnetic rotating along longitudinal shaft, a stator coil coordinating to periphery of rotator and basically setting in coaxial with rotator longitudinal shaft and a stator coordinating to periphery of stator coil and basically setting in coaxial with longitudinal shaft of rotator. It features that variation between rotator vibration angles under end value of stator coil Ac frequency range and under initial value of stator coil AC frequency range is not greater than 30 %.

Description

technical field [0001] The present invention relates to the field of alternating current (AC) electric motors. More specifically, in various embodiments, the present invention relates to electric motors with axial vibration transmission. Background of the invention [0002] Small AC vibrating motors can be used in hand-held body care devices. Specifically, these motors can be used in body care devices ranging from beauty care devices that gently massage the face to treat wrinkles, to devices that provide sexual stimulation to people suffering from sexual dysfunction. [0003] Ordinary AC vibrating motors usually draw power from the main AC power supply to get enough power. To increase mechanical energy output, common AC motors can use asymmetrical reluctance between the stator and rotor. However, due to the presence of asymmetric reluctance, when power to the motor is cut off, the rotor rotates to an undesired position and becomes magnetically locked in the undesired posi...
