Spliced permanent magnet motor rotor structure

The invention provides a spliced permanent magnet motor rotor structure, which is characterized in that 2p identical rotor fan-shaped iron core units are spliced along the circumferential direction of a rotor iron core to form a complete rotor iron core, and the rotor fan-shaped iron core units are mutually spliced to form magnetic steel grooves along the circumferential direction of the rotor iron core, compared with the existing integral circular magnetic conductive steel sheet, the rotor structure adopts the modular design of the rotor iron core, simplifies the processing steps and difficulty, increases the manufacturing speed of the rotor iron core of the permanent magnet motor, effectively reduces the processing cost, and is suitable for industrial mass manufacturing; and when the rotor breaks down, only the fan-shaped iron core unit at the fault position needs to be replaced, the whole rotor does not need to be replaced, and the later maintenance cost is effectively reduced. 本发明提供一种拼接式的永磁电机转子结构，将2p个相同的转
