| 摘要 |
The invention relates to a polyphase electric motor comprising a stator (1) having at least three coils (33, 43, 36, 46, 37, 47) and made up of 12.K radially extending teeth and a rotor (2) having 5.K pairs of magnetic poles, K being equal to 1 or 2, the rotor (2) being made up of a core (150) made of a ferromagnetic material and having an alternation of 5K magnetised poles, and 5K non-magnetised salient poles, characterised in that the stator (1) has teeth (3, 6, 7, 13, 16, 17, 20, 21, 22, 23, 24, 25) with rectangular or trapezoidal cross-sections converging towards the centre of the motor. |
