Embodiment 1

[0027] An alloy material used to manufacture motor rotors, calculated by weight percentage, its raw material composition and content are as follows:

[0028] Copper 95%

[0029] Iron 5%.

[0030] The above-mentioned method for preparing an alloy material for manufacturing a motor rotor, the specific steps are as follows:

[0031] (1), melting

[0032] First, the raw materials copper and iron are placed in a melting furnace for smelting. The temperature of the alloy liquid obtained after smelting is controlled at 1500-1550°C and kept for 20-30 minutes, and then the temperature of the alloy liquid is reduced to 250°C under the isolation of nitrogen, and then again Carry out heating up to 800°C;

[0033] (2), casting

[0034] Control the temperature of the alloy liquid obtained in step (1) to 800°C in the ladle for constant temperature casting. In order to ensure the quality of the casting, enough gates should be left;

[0035] (3), quenching treatment

[0036] After consta...

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an alloy material for manufacturing a motor rotor and a preparation method thereof. Background technique [0002] With the acceleration of industrialization, the efficiency of motors has become the focus of motor manufacturing. Improving the efficiency of motors is of great significance to energy conservation, environmental protection and even sustainable economic development. Using new materials to improve motor efficiency as much as possible has become an urgent task for motor manufacturers. [0003] In the measures to improve the efficiency of the motor, the selection of the rotor material is particularly important, which has a great impact on the stator copper loss, iron loss and other properties, and the cost of the iron core material is the main part of the cost of the motor. In the rotor design of high-performance motors, some alloy materials need to be used. ...
