Coaxial double-rotor permanent magnet direct current motor

The invention discloses a coaxial double-rotor permanent magnet direct current motor and relates to the technical field of motors. The motor consists of a shell 6, a left end cover 14, a right end cover 4, a left end bearing 13, a right end bearing 5 and a motor shaft 2, wherein at least more than two pairs of permanent magnets 10 of which the polarities are arranged in a staggered mode are fixed to the outer cylindrical surface of the motor shaft 2; a squirrel-cage auxiliary rotor consisting of squirrel-cage racks 11 and squirrel-cage bars 8 is also sleeved on the outer cylindrical surface of each permanent magnet 10; and a stator component consisting of a stator core (12) and a stator winding 7 arranged on the stator core 12 is fixedly arranged on the inner wall of the shell 6. The motor has the characteristics of high energy conversion efficiency, capability of enhancing motor power under the condition of the same volume and the like and can be widely applied in the fields of high-power electrical appliances, such as electric automobiles, electro-tricycles and the like.
