Abstract
The utility model relates to an asynchronous starting permanent magnet synchronous motor based on a sealing structure. The motor comprises a stator, a rotor and a casing. The rotor is arranged on a motor shaft. One end of a motor output shaft is arranged on a front end cover of the casing. The front end cover is connected with the casing body and a rear end cover to form the casing. The rotor is a cast aluminum rotor in which magnet steel is embedded. A shielding baffle is arranged between the casing body and the rear end cover. The stator is arranged on the shielding baffle. The stator comprises a stator tooth body and a stator yoke part. The stator tooth body is L-shaped, and the straight end passes through the shielding baffle to fit the stator yoke part. The L-shaped hook part of the stator tooth body is effectively aligned with the rotor. The rear end cover is connected and sealed with the stator yoke part and the shielding baffle to form a stator cavity. The stator tooth body is wound with a stator winding. The stator winding is located in the stator cavity. According to the utility model, the stator and the rotor of the motor are completely isolated; simply by using static sealing, the stator winding is protected, and the sealing effect is great; and the motor has the advantages of safe running and less failure.
