Problems solved by technology

Due to the use of centralized winding in this patent, it saves material compared with the traditional distributed winding stator, but the manufacturing process of this stator is relatively complicated, and it is difficult to splice each split iron core (considering the length and position of the transition line, At the same time, it is necessary to manually align one by one to splice, and a slight deviation will easily lead to splicing failure) and low efficiency and low yield, and it is difficult to guarantee the size of the stator core body that is split and spliced ​​in this way, and the coaxiality of the motor stator is very demanding. High, some slight deviations have a great influence on the performance of the motor, so the performance of the motor produced by this type of stator is unstable. In addition, the stator made by splicing is also poor in rigidity and easy to deform

Abstract

The invention discloses a single phase capacitor operating type motor stator and a manufacture method thereof. The stator comprises an integral stator core, two insulation reels and a centralized winding. The manufacture method of the single phase capacitor operating type motor stator comprises the following steps of: blanking, stacking, installing the insulation reels, coiling the winding, arranging transition wires of the winding, and wiring the winding. The motor stator of the invention has the advantages of material saving, low power consumption, stable structure, large rigidity and long service life; convex poles are in three-section arc structures so that magnetic flows of three areas on one magnetic projecting pole generate phase differences in space and time to improve the performance of the motor; the manufacture method is simplified, two corresponding convex poles on the diameter of the stator are simultaneously wound in the mode of the centralized winding by using an internal winding machine; compared with the method of connecting in series one by one after cutting the single convex pole of the core, the wind efficiency is at least doubled. The invention has the advantages of simple technique process, high efficiency and high rate of finished products.

Description

technical field [0001] The invention relates to a motor stator and a manufacturing method thereof, in particular to a single-phase capacitor running motor stator and a manufacturing method thereof. Background technique [0002] Existing AC motors, especially small AC motors suitable for household electrical appliances, such as capacitor-operated motors, mostly use distributed windings for their stator windings. Due to the structural limitations of distributed windings, they can only be manually embedded. Its embedding method is: first use a coil mold to wind the pre-designed coil size, number of coil turns, wire diameter and insulation grade to be achieved, and then wind the wound coil according to the pre-designed cross-slot Manually insert the winding into the slot of the stator. Since the wire is embedded manually, there should be enough space and length for the coil. When winding the main winding, there must be enough space to put it in. The auxiliary winding can only b...
