The invention discloses a permanent magnet frequency conversion all-in-one machine, which comprises a shell, a stator, a rotor, a frequency conversion module and a water cooling plate. The stator andthe rotor are arranged in the shell, the rotor is inserted into the stator, and the water cooling plate is arranged between the frequency conversion module and the shell; the stator comprises a statoriron core and a winding, the inner surface of the stator iron core is provided with a plurality of groove structures, the winding is arranged in the groove structures, positioning insertion strips are further arranged at openings of the groove structures, and the positioning insertion strips abut against the winding; the rotor comprises a rotating shaft, a rotor iron core, a permanent magnet anda mounting bracket, a shaft hole is formed in the mounting bracket, and the rotating shaft is mounted in the shaft hole; and the rotor iron core is of a sleeve structure, and the rotor iron core is arranged outside the mounting bracket in a sleeving manner. The weight of the permanent magnet frequency conversion all-in-one machine is reduced, and the use reliability is improved.
Description
technical field [0001] The invention relates to a motor, in particular to a permanent magnet frequency conversion integrated machine. Background technique [0002] Motors are commonly used electrical components in industrial production. Among them, permanent magnet frequency conversion integrated machines are widely used in industrial production because of their high efficiency and small size. The permanent magnet frequency conversion integrated machine generally includes a stator and a rotor, wherein winding coils are arranged on the stator, and permanent magnets are arranged on the rotor. In the prior art, the rotor core of the rotor is usually a solid structure, which makes the permanent magnet frequency conversion machine heavier; at the same time, the windings wound on the stator core in the stator are prone to fall off after long-term use ; How to design a light-weight and highly reliable permanent magnet frequency conversion integrated machine is the technical proble...
