The invention belongs to the technical field of permanent magnet motor. In order to solve the technical problem of tooth loosening often occurring after pressing the core of the embedded permanent magnet motor rotor, an embedded permanent magnet motor rotor pressure coil is provided, including the rotor pressure coil body. The outer edge of the rotor pressure coil body is evenly spaced along its circumference with a number of poles, each pole is provided with a magnet steel installation square hole, and each magnet steel installation square hole. There is a closing bolt hole for installing the magnetic pressure plate, and a pressing step is arranged on the surface where the rotor pressure ring body and the rotor punch piece fit together. The invention has the advantages of simple structure, high reliability, convenient manufacture, and can effectively improve the magnetic loading efficiency of the embedded permanent magnet motor. By setting a pressing step on the surface where the rotor pressure coil body and the rotor punch sheet fit together, the phenomenon of tooth loosening after pressing the rotor core can be eliminated, and the performance of the permanent magnet motor can be further improved by setting \V\ ventilation between the two adjacent poles on the rotor pressure coil body. The slot can effectively improve the ventilation between poles.
