Abstract
The utility model relates to a spinning frame motor-type spindle based on an asynchronous starting permanent magnet synchronous motor. The spinning frame motor-type spindle based on the asynchronous starting permanent magnet synchronous motor comprises a winding sealing shell body and a spindle outer shell body. An installation cavity is formed by the winding sealing shell body and the spindle outer shell body. A motor rotor and a motor stator are installed inside the installation cavity. The motor rotor is a cast-aluminum rotor, and magnetic steel is embedded into the motor rotor. One end of the motor rotor stretches out of the installation cavity to be connected with a spindle blade. The motor stator comprises a stator tooth body and a stator yoke portion. The stator tooth body is in an L shape. The straight end of the L-shaped stator tooth body penetrates through a stator winding partition plate to be in fit with the stator yoke portion. The hook end of the L-shaped stator tooth body effectively aligns at the motor rotor. The stator yoke portion and the winding sealing shell body are of an integral structure. The stator winding partition plate and the winding sealing shell body are connected and sealed to form a stator cavity. A stator winding is wound on the stator tooth body. The stator winding is located inside the stator cavity. Compressed air is filled into the stator cavity. The spinning frame motor-type spindle based on the asynchronous starting permanent magnet synchronous motor can be used for protecting the spinning frame motor-type spindle winding against aging and damage caused by the influence of dust.
