Problems solved by technology

[0002] The slot insulation of low-voltage motors has always followed the traditional insulation structure, that is, slot bottom insulation plus cover insulation. When larger motors adopt this insulation structure, due to the requirements for the thickness of the insulating paper, when the thickness of the insulating paper reaches 0.3mm and above , the hardness is relatively high, it is not easy to bend, and it is difficult for the wire inserter to operate; and when inserting the wire, when the electromagnetic wire is embedded in the slot, it is easy to scratch the insulation layer of the electromagnetic wire at the slot, resulting in inter-turn breakdown. Affect the quality of the motor

Embodiment Construction

[0012] see figure 1 , a low-voltage motor slot insulation structure, including a slot body 1, along the inner wall of the slot body 1, a first layer of insulating paper 2 and a second layer of insulating paper 3 with the same thickness are sequentially arranged, and the two layers of the second layer of insulating paper 2 The ends respectively extend from the notch of the tank body 1, and the magnet wire guide opening 4 is formed between the two ends of the second layer of insulating paper 3.

[0013] see figure 2 After inserting the magnet wire 5 into the groove body 1 along the magnet wire guide port 4, use a special tool to cut off the end of the redundant second layer of insulating paper 3, that is, to make the magnet wire guide port 4, the second The two ends of the layers of insulating paper 3 meet together on the inside of the notch of the tank body 1 , and then insert the slot wedge 6 inside the notch of the tank body 1 .

Abstract

The invention discloses a low-voltage motor slot insulation structure. The low-voltage motor slot insulation structure comprises a slot body. A first layer of insulation paper and a second layer of insulation paper are sequentially arranged along the inner wall of the slot body, the two ends of the second layer of insulation paper extend out from the slot opening of the slot body, and an electromagnetic wire leading opening is formed between the two ends of the second layer of insulation paper. The low-voltage motor slot insulation structure is reasonable and reliable; by combining the two layers of insulation layer of the same thickness to replace a single layer of thick insulation paper and adopting the leading slot structure, operation easiness is improved, the phenomenon that an electromagnetic wire is scratched at the slot opening is greatly reduced, and the probability of interturn breakdown of a motor is decreased.

Description

technical field [0001] The invention relates to the field of motor components, in particular to an insulating structure for a slot of a low-voltage motor. Background technique [0002] The slot insulation of low-voltage motors has always followed the traditional insulation structure, that is, slot bottom insulation plus cover insulation. When larger motors adopt this insulation structure, due to the requirements for the thickness of the insulating paper, when the thickness of the insulating paper reaches 0.3mm and above , the hardness is relatively high, it is not easy to bend, and it is difficult for the wire inserter to operate; and when inserting the wire, when the electromagnetic wire is embedded in the slot, it is easy to scratch the insulation layer of the electromagnetic wire at the slot, resulting in inter-turn breakdown. affect the motor quality. Contents of the invention [0003] The purpose of the present invention is to provide a low-voltage motor slot ins...
