Problems solved by technology

[0003] Although the existing manufacturing method can form a copper ring on the outside of the laminated silicon steel sheet, when the molten copper water is poured into the mold in the existing motor rotor manufacturing method, it mainly depends on the flow of the molten copper water in the mold to fill the ring. The entire mold is used to form the copper ring outside the laminated silicon steel sheet. However, the molte

Abstract

A manufacturing method of a motor rotor comprises the steps of preparing a plurality of silicon-steel plates, a shaft lever, and a mould provided with both an injection opening and a suction opening, sleeving the shaft lever into the laminated silicon-steel plates, placing the shaft lever and the silicon-steel plates into the mould, conducting suction by the suction opening to allow the interior of the mould to be in a vacuum state, injecting molten copper into the mould via the injection opening, allowing the molten copper to flow to the suction opening under the effect of the vacuum state, so as to be filled in the whole mould, cooling the mould, allowing the molten copper to form a copper ring on the silicon-steel plates, and cooling to the room temperature, thereby accomplishing the manufacturing of the motor rotor. The manufacturing method of the motor rotor can increase the product yield.

Description

technical field [0001] The invention relates to a method for manufacturing a motor rotor, in particular to a method for manufacturing a motor rotor that can improve product yield. Background technique [0002] When the existing motor rotor is manufactured, a plurality of silicon steel sheets are first laminated and then positioned through a shaft, and the shaft and the silicon steel sheets are heated and put into a mold, and a molten copper water is poured into the In the mold, a copper ring is formed on the outside of each silicon steel sheet, and after cooling, the mold is opened to take out the silicon steel sheet with the copper ring and the shaft rod, which completes the manufacture of the existing motor rotor; [0003] Although the existing manufacturing method can form a copper ring on the outside of the laminated silicon steel sheet, when the molten copper water is poured into the mold in the existing motor rotor manufacturing method, it mainly depends on the flow of...
