The invention belongs to the technical field of motors, and particularly relates to a disc type transverse flux permanent magnet brushless motor with a double-step stator, which comprises a stator and a rotor, the stator comprises a stator disc and phase armature units sequentially arranged at the lower part of the stator disc along the circumferential direction, and the rotor comprises a rotor disc and a permanent magnet array fixed at the upper part of the rotor disc along the circumferential direction. Each phase armature unit comprises two sub-armature units, n phase armature iron cores of each sub-armature unit are alternately arranged at intervals in the circumferential direction, and every two adjacent phase armature iron cores are oppositely arranged, so that winding materials can be saved, assembly is convenient, and more phase armature iron cores can be installed to improve the torque density; and harmonic waves are reduced by adopting a true fractional slot concentrated winding mode. The motor is s
