Insulating framework and motor

Abstract

The invention relates to the technical field of electrical equipment, and specifically relates to an insulating framework and a motor. The insulating framework comprises a first winding frame and a second winding frame, wherein the first winding frame and the second winding frame are arranged adjacent to each other; the first winding frame includes a first winding body and an outer packaging part, the second winding frame includes a second winding body and an inner packaging part, and the first winding body and the second winding body are used for mounting windings; in the radial direction of the insulating framework, the outer packaging part is connected to the outer side of the first winding body, the inner packaging body is connected to the outer side of the second winding body, the outer packaging body is located on the outer side of the inner packaging part, and at least part of the orthographic projection of the outer packaging part along the radial direction of the insulating framework is located on the inner packaging part. The outer packaging part and the inner packaging part in the insulating framework can provide a packaging protection effect for the windings, thereby preventing the yoke part from scratching wires of the windings, preventing the yoke part from pushing the wires of the windings out of a gap of the winding frames, and thus being capable of improving the production efficiency and yield of the stator.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an insulating frame and a motor. Background technique [0002] As an important power output device, the motor is widely used in machine tools and various control systems. The motor usually includes a stator and a rotor. For the stator structure, the common types include the segmented iron core type and the tooth-yoke separation type. In the tooth-yoke separation structure, the stator teeth extend into the insulating frame, and the windings are wound on On the winding frame of the insulating frame, the stator yoke is sheathed outside the insulating frame. However, affected by the processing technology and processing accuracy, part of the wires on the completed winding may protrude from the gap between two adjacent bobbins and be exposed, so that the stator yoke, insulating frame and stator During the process of nesting the teeth, the yoke may scratch the insulating ...

Problems solved by technology

However, affected by the processing technology and processing accuracy, part of the wires on the completed winding may protrude from the gap between two adjacent bobbins and be exposed, so that the stator yoke, insulating frame and stator During the process of nesting the teeth, the yoke may scratch the insulating paint of the wire, causing the wire to communicate with the stator yoke, and even the wire may be pushed out from the gap between adjacent winding frames by the yoke. Phenomenon, lead to invalidation of the stator, increase production cost, reduce production efficiency
