Vibrating motor

Abstract

A power supply device consists of output circuit, traveling contact, tripping coil, converter, grating signal forming circuit, reset signal forming circuit and LED. Said invention can convert the leakage switching function into normal stand-by state as traveling contact recovering close position in tripping when detecting leakage, the LED lighting when traveling contact switching off and lighting off when traveling contact recovering switching on.

Description

【Technical Field】 [0001] The invention relates to a motor, in particular to a vibration motor. 【Background technique】 [0002] With the rapid development of electrical appliances, many electrical appliances developed and used on the market have built-in vibration motors. Such as figure 1 As shown, a conventional vibration motor 1 includes a housing 11 and a movement group 12 pivoted on the housing 11. [0003] The housing 11 has a stator 111, and the stator 111 is wound with a predetermined number of coils. The movement group 12 includes an inverted U-shaped hub 121, a rotating shaft 122 extending vertically downward from the bottom surface of the hub 121 and passing through the stator 111, and a magnet 123 disposed on the inner peripheral surface of the hub 121 and surrounding the stator 111. , And a metal eccentric 124 fixed on the outer peripheral surface of the hub 121. [0004] When the vibrating motor 1 is energized, the stator 111 forms an induced magnetic field and inter...

AI Technical Summary

Problems solved by technology

[0005] The vibrating motor 1 is driven by the rotating shaft 122 and the hub 121 through the eccentric part 124 to generate vibration. Although it can provide warning and notification functions for electrical appliances, the following problems cannot be avoided:

[0007] like figure 1 As shown, the length of the moment arm from the center of the pivoting place of the rotating shaft 122 to the magnet ring 123 is a, but because the moment arm length a is relatively short, the moment of the movement group 12 is relatively small, causing the movement group 12 to The vibration efficiency generated is poor, so the warning and notification effect cannot be effectively exerted

[0008] 2. The volume occupied by the vibration motor 1 cannot be reduced

[0009] In the vibration motor 1, the biggest factor affecting the overall occupied volume is the pivot joint between the motion group 12 and the housing base 11, where the motion group 12 and the stator 111 that can cause the vibration motor 1 to vibrate regularly are arranged. As a result of the pivotal arrangement of the group 12 and the stator 111, the two volumes have an additive effect. In this way, if the vibration motor 1 is installed in an electrical appliance, the occupied volume cannot be reduced, and of course the vibration motor 1 will be reduced. use value
