PROBLEM TO BE SOLVED: To provide an electric machine which is capable of decreasing the cogging torque and reducing a magnetic loss, further, facilitates manufacture and assembly and reduces cost of manufacture.SOLUTION: An electric machine includes a rotor and a stator. The stator is disposed near to the rotor and has at least one first stator unit and at least one second stator unit. The first stator unit has a first protruding tooth and a second protruding tooth. The second stator unit has a third protruding tooth and a fourth protruding tooth. The rotor has a rotating direction or a moving direction with respect to the stator, and the first protruding tooth of the first stator unit and the third protruding tooth of the second stator unit are adjacently installed to each other along the rotating direction or the moving direction. The protruding directions of the first protruding tooth and the third protruding tooth respectively form a first angle and a third angle which are different, with a radial direction of the rotor. |
