Motor rotor structure and end face motor

A motor rotor structure and an end face motor are provided. The motor rotor structure comprises a rotating end cover which comprises a first surface and a second surface; the second surface is provided with a mounting groove; and the rotor assembly is arranged in the mounting groove. The rotor assembly comprises a plurality of permanent magnets which are arranged in parallel, and the plane where the magnetic poles of the permanent magnets are located is parallel to the second surface. The permanent magnet in the rotor assembly is a flat permanent magnet, and is parallel to the rotating end cover, thereby facilitating the reduction of the axial size of the rotor part, and achieving the assembly of the ultra-thin end face motor. According to the end face motor applying the motor rotor structure, the rotor assembly is located above the stator assembly, and the end face motor has the advantages of being compact in internal structure and small in axial length, is suitable for low installation height and saves inst
