Rotor de machine electrique tounante munie d'une repartition optimisee d'aimants interpolaires

The invention relates mainly to a rotor (12) of a rotating electric machine, in particular for a motor vehicle, comprising: - a first pole wheel (27.1) comprising a series of claws (29.1), - a secondpole wheel (27.2) comprising a series of claws (29.2), - the claws (29.1) of the first pole wheel (27.1) and the claws (29.2) of the second pole wheel (27.2) being nested relative to each other, so that two claws ( 29.1, 29.2) adjacent belong to two different pole wheels (27.1, 27.2), - two adjacent claws (29.1, 29.2) being separated from each other by an interpolar space (42), characterized in that permanent magnets (43) are arranged inside only part of the interpolar spaces (42). 本发明主要涉及一种用于特别是用于机动车辆的旋转电机的转子(12)，包括：-包括一系列爪(29.1)的第一磁轮(27.1)；-包括一系列爪(29.2)的第二磁轮(27.2)；-第一磁轮(27.1)的爪(29.1)和第二磁轮(27.2)的爪(29.2)相对于彼此边缘重叠，使得两个相邻的爪(29.1、29.2)属于两个不同的磁轮(27.1、27.2)；-两个相邻的爪(29.1、29.2)通过极间空间(42)彼此分开，其特征在于，永磁体(43)仅设置在极间空间(42)的一部分内。
