Easy-to-start motor and base thereof

Abstract

The invention provides an easy-to-start motor for overcoming the problems that a conventional motor base has poor structural strength; and an induction sheet is easy to fall off and cannot obstruct electromagnetic interference. The easy-to-start motor includes a base, a stator and a rotor. The base has a plastic member and a metallic induction member wrapped with the plastic member. The metallic induction member includes at least one magnetic attraction portion. Each magnetic attraction portion is in the form of a protrusion. The stator is coupled with the base. The rotor has a central shaft and a permanent magnet. The central shaft is capable of being coupled with the base. The at least one magnetic attraction portion is magnetically attracted by the permanent magnet, so as to prevent the rotor from stopping at a dead location under a static state.

Description

technical field [0001] The invention relates to an easy-to-start motor and its base; in particular, it relates to a motor and its base which can prevent the rotor of the motor from being at the starting dead point when it is stationary, and can effectively block electromagnetic waves. Background technique [0002] Existing motors that can solve starting difficulties are available, such as the invention patent of No. 96108993 "Printed Circuit Board Fixing Structure of Micro Motors" applied in Taiwan, China. The existing printed circuit board fixing structure 9 includes a base 91 and a printed circuit board 92; the center of the base 91 is provided with a shaft tube 911, and the periphery of the shaft tube 911 is provided with several grooves 912 and several positioning posts 913, each of the plurality of grooves 912 is embedded with an induction piece 914; the printed circuit board 92 is sleeved on the shaft tube 911 of the base 91, and the printed circuit board 92 is fixed o...

AI Technical Summary

Problems solved by technology

Among them, the above-mentioned base 91 must be provided with several grooves 912 for accommodating the several induction chips 914. Therefore, the axial thickness of the position corresponding to the several grooves 912 of the base 91 is relatively weak, which is easy to affect the Overall structural strength of base 91

[0004] Also, the above-mentioned base 91 must be provided with the plurality of positioning posts 913 to ensure that the above-mentioned printed circuit board 92 can be fixed on the surface of the base 91, so that the printed circuit board 92 can be further used to effectively press against and position the above-mentioned several inductive pins. sheet 914 to prevent the plurality of sensing sheets 914 from falling off from the base 91; however, the plurality of positioning posts 913 formed on the surface of the base 91 may cause cracks when the printed circuit board 92 is fixed for a long time. Or even broken, etc., therefore, it is easy to lose the original function of fixing the printed circuit board 92, causing the printed circuit board 92 to be unable to effectively prevent the plurality of sensing pieces 914 from falling off. Therefore, the above-mentioned existing printed circuit board fixing structure 9 is used for The fixing effect of fixing the several induction plates 914 is not good

[0005] In addition, the above-mentioned several induction plates 914 are only used to avoid the difficulty in starting the motor, and the above-mentioned base 91 is generally made of plastic injection molding. When the above-mentioned existing printed circuit board fixing structure 9 is applied to the interior of various electronic devices, by The base 91 made of plastic material cannot form a barrier that can completely block electromagnetic waves, and although the plurality of induction plates 914 are made of metal material, the effect of the number of induction plates 914 that can block electromagnetic waves is not obvious. Therefore, the electromagnetism generated during the operation of the existing printed circuit board fixing structure 9 may still interfere with the relevant electronic components inside the electronic device, resulting in unstable operation of the electronic device
