Abstract
The invention provides a manufacturing technology for a motor rotor. A raw material of the motor rotor comprises, by weight, 70 percent of pure aluminium, five percent of ferrochrome and 25 percent of alumal. A preparation method for the motor rotor comprises the following: step one, the pure aluminium is melted; step two, the ferrochrome and the alumal are subjected to hammer-milling and are prepared in proportion for later usage; step three, the melted pure aluminium is continuously heated to 700 DEG C, and a prepared ferrochrome and alumal mixture is poured into molten aluminum; step four, stirring is carried out, and after full fusing is completed, a modificator is added, and modification treatment is carried out; step five, the motor rotor is formed by pouring molten liquid into a die. According to the manufacturing technology for the motor rotor, the manufacturing technology is simple, the service life of the rotor is long, the raw material of the rotor can be conveniently provided, the distribution is wide, the manufacturing cost is low, and the manufacturing technology is beneficial to large-scale popularization.
