Motor stator structure

Abstract

A motor stator structure includes a main body and multiple stopper plates. The main body has multiple magnetic poles and a shaft hole. The magnetic poles outward extend from the main body. Each magnetic pole has a free end outward extending from the main body. The shaft hole passes through the main body between two ends thereof. The stopper plates are respectively correspondingly assembled with the free ends of the magnetic poles. In the motor stator structure, the windings are more densely wound on the magnetic poles to enhance the magnetization efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Please refer to FIGS. 1 and 2. FIG. 1 is a perspective exploded view of a first embodiment of the motor stator structure of the present invention. FIG. 2 is a perspective assembled view of the first embodiment of the motor stator structure of the present invention. According to the first embodiment, the motor stator structure 1 of the present invention includes a main body 1 and multiple stopper plates 12.

(8) The main body 11 has multiple magnetic poles 111 and a shaft hole 112. The magnetic poles 111 outward extend from the main body 11 and are annularly arranged on the outer circumference of the main body 11. Each magnetic pole 111 has a free end 111a outward extending from the main body 11. The shaft hole 112 passes through the main body 11 between two ends thereof. The main body 11 is composed of multiple silicon steel sheets 113 stacked on each other.

(9) The stopper plates 12 are respectively correspondingly assembled with the free ends 111a of the magnetic poles 111. Multiple windings 114 are wound around the magnetic poles 111.

(10) Please now refer to FIGS. 3a and 3b. FIG. 3a is a top view of a second embodiment of the motor stator structure of the present invention. FIG. 3b is a top view of the second embodiment of the motor stator structure of the present invention. The second embodiment is partially identical to the first embodiment in structure and thus will not be repeatedly described hereinafter. The second embodiment is different from the first embodiment in that the second embodiment has a receiving space 115. The receiving space 115 is defined by the adjacent magnetic poles 111 and the stopper plates 12. The configuration and size of the receiving space 115 are related to the number of the magnetic poles 111 and the distance between the magnetic poles 111.

(11) In the case that the number of the magnetic poles 111 is less, then the receiving space 115 is larger and the receiving space 115 has a quadrangular configuration. In the case that the number of the magnetic poles 111 is more, then the receiving space 115 is smaller and the receiving space 115 has a triangular configuration.

(12) Please now refer to FIG. 4, which is a top view of a third embodiment of the motor stator structure of the present invention. In the third embodiment, each magnetic pole 111 has a connection end 111b opposite to the free end 111a. The connection end 111b is connected with the main body 11. The width of the free end 111a is larger than the width of the connection end 111b.

(13) The major object of the present invention is to connect the stopper plates 12 with the tail ends (the free ends 111a) of the magnetic poles 111 by way of assembling process. In this case, when winding the windings, the stopper plates 12 will not hinder the winding operation and the windings can be uniformly fully wound to occupy the entire receiving space 115. Finally, the stopper plates 12 are connected with the free ends 111a of the magnetic poles 111 to restrict the windings 114 from dropping.

(14) The motor stator structure of the present invention can improve the problem of the conventional stator structure that the wires can be hardly uniformly wound on the magnetic poles 111. In the present invention, the wires can be uniformly wound on magnetic poles 111. Also, the windings 114 can be respectively wound on the magnetic poles 111 with specific configuration.

(15) The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in such as the form or layout pattern or practicing step of the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
