description The utility model discloses an efficient DC permanent magnet motor. The motor comprises a housing. The inner side of the housing is provided with a stator. The inner side surface of the stator is provided with more than one stator bumps, and a rotor cavity is formed by the stator bumps. A rotor is installed in the rotor cavity. The side surface of the rotor is provided with concave-convex grooves integrally connected with the rotor. A permanent magnet is disposed in each concave-convex groove. The permanent magnets realize connection and fixation through the concave-convex grooves. A coil is winded on the stator bumps. The T-shaped concave-convex grooves are used to fix the permanent magnets, and thus, magnetic field intensity is increased by 20% to 60%, iron loss is reduced, torque of a motor in a same volume is improved, power is increased, and heat is reduced.
