Embodiment 1

[0035] combined with figure 1 As shown, this embodiment provides an insulating skeleton, including several skeleton units, the insulating skeleton includes an outer part 1, an inner part 2 and a winding part 3, and the winding part 3 is located between the outer part 1 and the inner part 2, It is also used for winding wires, and the wires are enameled wires 10; specifically, the outer part 1 and the inner part 2 are similar to plate-shaped structures, and the winding part 3 includes two oppositely arranged side plates 4, and is arranged on two sides A top plate 5 between the plates 4 and connected to the two side plates 4 respectively, and a bottom plate 6 arranged between the two side plates 4 and connected to the two side plates 4 respectively, the two side plates 4 and the top plate 5 Together with the bottom plate 6, a connecting groove 16 is formed, and the connecting groove 16 is used for connecting with the tooth portion 18 of the stator.

[0036] It should be noted th...

Embodiment 2

[0051] combined with Figure 8 and 9 As shown, this embodiment provides a stator assembly, which includes a stator core and an insulating frame as described in Embodiment 1. The stator core includes a yoke portion 17, a tooth portion 18, and a circuit board assembly 19; the circuit board assembly 19 and The pins on the insulating frame are connected, and the stator core tooth portion 18 is connected to the insulating frame. Of course, except for the insulating frame of this embodiment, the structure and specific connection relationship between the yoke portion 17 and the tooth portion 18 and the circuit board assembly 19 They are all common knowledge in the field, so this embodiment does not describe them too much.

Embodiment 3

[0053] combined with Figure 10 As shown, the present embodiment provides a motor, which includes the stator assembly in the second embodiment, the casing 20, the rear end cover 21, the rear bearing 22, the front end cover 23, the front bearing 24 and other parts, and its specific structure is in addition to the insulation The skeleton is the same as that of the prior art, so this embodiment does not repeat the functions and connections of each component.

Abstract

The present invention discloses an insulating skeleton, and a stator assembly and a motor therewith. The insulating skeleton comprises an outer portion, an inner portion and a winding portion; the winding portion is arranged between the outer portion and the inner portion and is used for winding; the winding portion has two side plates arranged oppositely; the outer wall of the side plate is provided with a plurality of spaced apart first ribs; and a first accommodating gap is arranged between adjacent two windings in the innermost layer of the side plate, and at least one of the first ribs isarranged in the first accommodating gap. According to the insulating skeleton provided by the present invention, a plurality of first ribs are arranged on the side plate; and even though the first ribs are arranged in the first accommodating gap between the adjacent two windings, the winding is not affected, and the first ribs form a reinforcing rib structure, so that the structural strength of the side plates is improved to prevent the side plates from being broken, and the reliability of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an insulating skeleton, a stator assembly and a motor with the same. Background technique [0002] A general motor is composed of a stator, a rotor, a casing and other components. The stator includes a stator core, an insulating structure and a winding. The winding is wound on an insulating skeleton, and the winding is usually an enameled wire. [0003] However, in order to increase the winding space of the enameled wire in the existing insulating skeleton structure, the skeleton is designed to be very thin, and the strength of some areas is insufficient. When the enameled wire is wound on the skeleton, the tension of the enameled wire will squeeze the skeleton, and the position where the number of enameled wire winding layers is large , the skeleton is easy to break, and the enameled wire and the stator core are in contact, causing the motor to break down.
