The invention relates to a difference modulation vernier permanent magnet motor with high torque density. The difference modulation vernier permanent magnet motor structurally comprises an outer stator and an inner rotor. The outer stator is composed of a stator yoke part 1, stator teeth and armature windings 4 from outside to inside, the stator yoke part 1 is a metal cylinder and internally connected with the V-shaped stator teeth, and the armature windings 4 are arranged between the adjacent stator teeth. And an air gap distance exists between the stator teeth and the outer surface of the inner rotor. The inner rotor comprises a rotor permanent magnet 5, a rotor iron core 6 and a rotor rotating shaft 7 in sequence from outside to inside, the rotor permanent magnet 5 and the rotor iron core 6 are cylindrical, the rotor rotating shaft 7 is cylindrical, and the rotor permanent magnet 5, the rotor iron core 6 and the rotor rotating shaft 7 are tightly connected in a sleeved mode and can rotate synchronously.
