The invention discloses an integrated motor of an energy-saving industrial sewing machine. The integrated motor comprises a shell, wherein a stator/rotor assembly is arranged in the shell and comprises a rotation shaft, a front end cover and a rear end cover are respectively arranged at the two ends of the shell, the rotation shaft extends out of the front end cover and the rear end cover, the front end of the rotation shaft is connected with the belt pulley, a groove is arranged on the rear end cover and sunken towards the inner side of the shell, a through hole is arranged at the middle of the groove and used for the rear end of the rotation shaft to extend out, a rear shell is further connected onto the rear end cover, a controller used for controlling the motor is arranged in the rear shell and comprises a circuit board and an electronic components arranged on the circuit board, a cooling plate is connected onto the circuit board and used for collecting heat of the controller, fan blades are arranged in the groove, connected with the rear end of the rotation shaft and used for blowing towards the cooling plate, and a cooling hole is further formed on the rear shell and used for dissipating heat in the rear shell. The integrated motor is compact in structure and low in cost, the fan blades of the motor are used for directly dissipating heat from the circuit board and the electronic component, and the integrated motor has a long service lifetime.
