The invention relates to an elevator motor (12) comprising a stator (16) having stator windings and a rotor (20) comprising permanent magnets (26), in which the magnets (26) of the rotor (20) and the windings of the stator (16) are arranged in an axial magnetic flux arrangement, the rotor (20) being connected to a traction sheave (22) for driving a hoisting rope (24) of an elevator, whereby the permanent magnets (26) are arranged in an annular arrangement on a carrier (28) of the rotor (20), a magnet ring (35) having grooves (30a, 30b) is formed therebetween. According to the invention, the groove width differs between at least some of the two consecutive grooves (30a, 30b) in the magnet ring (35). Such a permanent magnet motor has reduced noise propagation and is particularly suitable for residential elevators.

    本发明涉及一种电梯电机(12),包括具有定子绕组的定子(16)和包括永磁体(26)的转子(20),其中转子(20)的磁体(26)和定子(16)的绕组布置成轴向磁通布置,转子(20)连接到用于驱动电梯的提升绳索(24)的牵引绳轮(22),由此,所述永磁体(26)以环状布置布置在所述转子(20)的载体(28)上,以在其间形成具有槽(30a、30b)的磁体环(35)。根据本发明,槽宽度在磁体环(35)中的两个连续槽(30a,30b)中的至少一些之间不同。这种永磁电机具有降低的噪声传播,并且特别适用于住宅电梯。
