| 发明名称 | Rotary electric machine | ||
| 摘要 | A rotary electric machine includes: a stator having a stator winding and a stator core; a rotor having a first magnetic pole section and a second magnetic pole section, where the second magnetic pole section rotates respective to the first magnetic pole section; a shaft provided for the rotor; and a rotary mechanism configured to rotate the second magnetic pole section about the shaft. The rotary mechanism includes: a moving member configured to be movable along the shaft; a lead screw mechanism configured to move the moving member along the shaft; and a rotary member configured to rotate respective to the shaft along with the second magnetic pole section, where the rotary member engages the moving member and the second magnetic pole section. | ||

| 主权项 | 1. A rotary electric machine comprising: a stator having a stator winding and a stator core; a rotor having a first magnetic pole section and a second magnetic pole section, where the second magnetic pole section rotates respective to the first magnetic pole section; a shaft provided for the rotor; and a rotary mechanism configured to rotate the second magnetic pole section about the shaft, wherein the rotary mechanism includes: a moving member configured to be movable along the shaft;a lead screw mechanism configured to move the moving member along the shaft by acting on the moving member from an inside of the shaft; anda rotary member configured to rotate respective to the shaft along with the second magnetic pole section, where the rotary member engages the moving member and the second magnetic pole section. | ||
