The invention discloses an air-cooled permanent magnet motor based on a heat dissipation copper pipe, and aims to provide an air-cooled permanent magnet motor based on a heat dissipation copper pipe. According to the air-cooled permanent magnet motor based on the heat dissipation copper pipe, the problems of permanent magnet demagnetization, motor efficiency reduction, short service life and serious influence on the use performance of the motor due to the fact that the temperature rise of the motor is too high are effectively solved. The motor comprises a motor shell, a fan, a stator located in the motor shell, a heat dissipation air channel and a heat dissipation copper pipe assembly, an air outlet is formed in the rear end of the motor shell, the heat dissipation air channel comprises a plurality of annular air channels arranged on the outer circumferential face of the stator and a plurality of stator flow guide air channels arranged on the outer circumferential face of the stator, and the fan blows air tow
