【Abstract】 For a large-capacity synchronous motor in variable-frequency condition, the key techniques such as the electromagnetic calculation of the motor, the intensity calculations of the bolts connecting three section shafts and connecting magnetic poles, the reliability analysis technology of large rotating structure, the designs of large-torque low-speed rotor frequently withstanding forward and backward impact, the ventilation cooling technologies of slip ring and electric brush at low speed, the designs of big thrust sliding bearing, high-pressure oil jacking device and auxiliary oil station, and the reliability design, manufacture and modal analysis of stator are analyzed. The variable-frequency synchronous motor with high technical difficulties is developed, which meets the needs of users and creates technical support and economic value in a new field.更多还原
