Embodiment Construction

[0023] figure 1 It is a longitudinal sectional view of an angle grinder reluctance motor of the present invention. Among them, 1 grinding plate, 2 bearings, 3 shafts, 4 stator cores, 5 armature windings, 6 excitation windings, and 7 shells. A reluctance motor for an angle grinder, characterized in that 6 fan-shaped through holes are evenly distributed on the circumference of the grinding disc fixed on the shaft, and there are grinding disc ribs made of magnetically conductive material between the two fan-shaped through holes ; The shell is connected to the shaft through the bearing.

[0024] The stator core is composed of three "匚"-shaped sub-stator cores. Each sub-stator core is symmetrically distributed on both sides of the grinding plate and fixed on the shell. The difference between adjacent sub-stator cores is 40 degrees along the circumferential direction; each sub-stator core There is an armature pole on both sides facing the axis, and the end face of the armature pol...

Abstract

The invention discloses an angle grinder reluctance motor, which belongs to the technical field of electric tools. The angle grinder reluctance motor is composed of a disc, a bearing, a shaft, a stator iron core, an armature winding, an excitation winding and a shell, wherein the circumference of the disc fixed on the shaft is uniformly distributed with six fan-shaped through holes; a disc rib made of a permeability magnetic material is arranged between two fan-shaped through holes; the stator iron core is formed by three [-shaped sub stator iron cores, the sub stator iron cores are symmetrically distributed at two sides of a saw blade and is fixed on the shell, and the adjacent sub stator iron cores form a 40 DEG along a circumferential direction; two sides of each sub stator iron core towards the axis are provided with armature poles; the yoke part of each sub stator iron core is wound with the excitation winding; and the root part of each sub stator iron core armature pole is woundwith a concentrated armature winding. Integration of a driving motor and the disc can be effectively realized, and the space and the cost are saved.

Description

technical field [0001] The invention relates to a reluctance motor of an angle grinder, which belongs to the technical field of electric tools. Background technique [0002] Angle grinder is a kind of equipment used to cut, grind and brush metal and stone. Its principle is to use high-speed rotating sheet grinding wheel or wire wheel to grind, cut, derust and polish metal components. The motor is the core component of the angle grinder. The performance of the motor affects the performance and working efficiency of the angle grinder. Therefore, it is very important to design a motor with excellent performance. [0003] From the current published patent applications, there are few patents related to the angle grinder motor, and most of the patents focus on the structure of the angle grinder body. For example, the patent application number is 201720070995.8: A stator fixing device for an angle grinder motor. The application device includes a stator fixing shell and a fixed ...
