The present disclosure relates to a double-stator PM machine (1) comprising: an outer stator (2a) generating an outer electromagnetic field dependent on an outer three-phase supply current (Io); an inner stator (2b) generating an inner electromagnetic field dependent on an inner three-phase supply current (Ii); a PM rotor (3) rotated by the outer and inner electromagnetic fields between the outerand inner stators; and a control arrangement (4) controlling the outer and inner supply currents. There is an electrical connection (7) between neutral points (No, Ni) of the outer and inner stators.The control arrangement is configured for controlling the outer and inner supply currents such that there is a relative angle shift of 30 degrees between the outer and inner supply currents and such that a third order current harmonic component is circulated between the outer and inner stators. 本公开涉及一种双定子PM机器(1)，该双定子PM机器(1)包括：外部定子(2a)，根据外部三相供电电流(Io)来生成外部电磁场；内部定子(2b)，根据内部三相供电电流(Ii)来生成内部电磁场；PM转子(3)，通过外部定子与内部定子之间的内部电磁场和外部电磁场而
