Abstract

The invention discloses a stator core, a winding type stator, a concentrated winding motor and a production method. The stator core comprises a yoke structure and a plurality of tooth structures; theyoke structure is divided into a plurality of yoke structure sections with the same number as the tooth structures; each yoke structure section is connected with each tooth structure in a mortise andtenon joint mode; and the yoke structure sections are sequentially connected end to end to form an annular yoke structure, and the tooth structures are located on the same circumferential line. According to the invention, the cost of the stator core is reduced, and the flux density in the tooth structures is reduced, so that the iron loss of the winding type motor is reduced, and the purpose of improving the performance of the winding type motor is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator core, a wound stator, a concentrated winding motor and a production method. Background technique [0002] Electric machines can have distributed windings or concentrated windings, the distinction between these windings being well known to those of ordinary skill. The stator in the centralized winding motor used in the existing frequency conversion air conditioner is a winding type variable frequency motor stator. The winding type motor stator is composed of a stator core and an enameled wire winding coil. After winding the winding coil on the stator core production. The stator core is in the shape of a full circle, and a certain number of grooves are opened on the stator core of the full circle structure for accommodating the wound enameled wire winding coils. The stator core of the full circular structure is prepared by stamping technology, or by winding technology, us...
