Motor stator structure based on liquid metal encapsulation

The invention belongs to the technical field of motor heat dissipation, aims to solve the problem of low heat dissipation efficiency of a motor casing caused by an air gap with a low heat conductivity coefficient between a motor stator core and the casing, and particularly relates to a motor stator structure based on liquid metal encapsulation. Comprising a motor shell, a stator iron core, a first sealing end ring, a second sealing end ring and liquid metal, a plurality of positioning pins are arranged on the inner wall of the motor shell, and a plurality of positioning grooves clamped with the positioning pins in a clearance mode are formed in the outer wall of the stator iron core; the first sealing end ring and the second sealing end ring are arranged at the top and the bottom of the stator core respectively, and the outer walls of the first sealing end ring and the second sealing end ring abut against the inner wall of the motor shell; the bottom of the first sealing end ring, the top of the second sealing end ring, the inner wall of the motor shell and the outer wall of the stator iron core form a closed cavity; the closed cavity is filled with the liquid metal; the heat conduction performance of the motor shell can be effectively improved, the heat dissipation efficiency of the motor shell is enhanced, and meanwhile normal, safe and stable operation of a motor is guaranteed.
