Stator of single-phase capacitor running salient-pole and non-salient-pole motor, and manufacturing method thereof

Abstract

The invention discloses a stator of a single-phase capacitor running salient-pole and non-salient-pole motor, and a manufacturing method thereof. The stator comprises a combined stator, a concentrated winding and two insulating winding frames, wherein the combined stator is formed by combining an inner stator and an outer stator, the outer stator adopts a regular polygonal ring structure with an inner cavity with a 2P number of edges, wherein P represents the number of poles of the motor, a 2P number of clamping grooves matched with salient and non-salient poles of the inner stator are pre-punched, and the inner stator is formed by circularly connecting a 2P number of salient and non-salient poles; and the two insulating winding frames are buckled on the upper side and the lower side of the inner stator and encircled at the waist parts of the salient and non-salient poles respectively, and a combined reel body is placed in the inner cavity of the outer stator and combined with the clamping grooves in a press fitting manner. The limitation that the winding depends on the manual embedding process and the inner winding process for the notch in the traditional motor manufacturing process is abandoned, the defects of low winding efficiency and high rejection ratio in the present stator inner winding type manufacturing process are overcome, and more stable and more efficient solutions are provided for the production and manufacture of a large amount of fully-automatic asynchronous motors.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator of a single-phase capacitor-operated hidden-salient pole motor and a manufacturing method thereof. Background technique [0002] Existing single-phase shaded-pole asynchronous motors, such as shaded-pole motors for household window exhaust fans, use a combined stator, which consists of an inner stator and an outer stator, and a single centralized coil and insulating wire frame are pre-wound. Finally, it is manually installed on the salient poles of the inner stator, and then the insulating wire frame, the inner stator assembly and the outer stator are press-fitted to form a composite stator, and then the transition line is arranged to connect the single centralized coils to complete the stator. The working principle is: the salient pole shoe of the inner stator is slotted and welded with a free-standing copper short-circuit ring. The salient pole magnetic pole is divided ...

[0004] Chinese invention patent ZL201010113410.9 (authorized announcement number is CN101807838B) discloses a single-phase capacitor-operated motor stator and its manufacturing method. The two salient poles facing each other on the diameter of the stator are wound in the way of concentrated winding at the same time. Due to the use of concentrated winding, it saves material compared with the traditional distributed winding stator, but it uses the inner winding method of the slot The operating speed of the winding machine is severely limited, resulting in low production efficiency of the single machine, high failure rate of the winding machine, and it is impossible to propose a specific implementation plan for the manufacture of the stator of the multi-speed asynchronous motor

[0005] Chinese invention patent 201110315032.7 (publication number CN102427282) discloses a capacitive-operated motor stator and its manufacturing method. The stator core adopts a split stator core. The method of wire reassembly and integration, split combination and pre-winding method is based on the manufacturing process of the above-mentioned shaded pole asynchronous motor, and the method of re-cutting and separating is a process for manufacturing a stator with slots; the stator manufacturing method The defect is: the pre-winding process of the winding is the same as the manufacturing process of the shaded pole asynchronous motor. The wound winding-wire sleeve combination is disassembled from the winding machine and then installed on the inner stator. The process must be done manually. As a result, the production efficiency is low, and the scrap rate is high, and there is no specific implementation plan for the manufacture of the stator of the multi-speed asynchronous motor
