INDUCTION MOTOR WITH LEAKAGE CURRENT PROTECTION Russian patent published in 2023 - IPC H02K5/04 H02K17/30 H02K5/08 H02K5/22 

FIELD: electrical engineering.

SUBSTANCE: leakage current induction motor consists of a rear housing, a cooling fan, a plastic housing, a stator, an end cover and a rotating shaft. The open end of the rear case and the plastic case are rigidly installed. The cooling fan is mounted inside the plastic case, and the stator is rigidly mounted inside the plastic case. The rotating shaft is movably fixed in the stator. One end of the plastic housing, remote from the rear housing, is rigidly connected to the end cap. The junction box is rigidly mounted on the surface of the plastic housing. The inner wall of the distribution box is movably connected to the sealing plate and rigidly connected to the connection post. The sealing plate is movable relative to the connection post and the junction box. The underside of the sealing plate is rigidly connected to the connecting frame. The plug-in block is connected to the connecting post with the possibility of being pulled out of it and inserted into the connecting frame when the connecting frame reaches the level of the plug-in block. The bottom side of the sealing plate is rigidly connected to the elongated post. The disc is connected to the surface of the elongated post with the possibility of sliding. The lower end of the elongated post is rigidly connected to the base, the surface of which is rigidly connected to the spring. One end of the spring, remote from the base, is rigidly connected to the disc. The spring is fixed on the surface of the elongated rack. The elongated rod is connected with the possibility of sliding with the disk, and the movable rod is connected with the possibility of sliding with the surface of the elongated rod.

EFFECT: simplifying the design and increasing the efficiency of use.
