The invention belongs to the technical field of motor and crane manufacturing, and provides a motor and winding drum integrated lifting device structure. A hollow main shaft penetrates through a stator iron core a, a stator iron core b and end covers. A lifting winding drum is arranged outside the stator iron core a and the stator iron core b. A stator coil a and stator coil b are separately arranged at the ends of the stator iron core a and the stator iron core b. A permanent magnet a and a permanent magnet b are arranged inside the lifting winding drum. The end covers are fixed on both sidesof the lifting winding drum. Rigid supporting seats are further fixedly connected with two ends of the hollow main shaft. Large synchronous wheels are fixed on an oil seal. Synchronous wheel mountingseats are fixed on the rigid supporting seats. Small synchronous wheels are fixed on the synchronous wheel mounting seats. The small synchronous wheels are connected with the large synchronous wheelsthrough synchronous belts. Height limiting stoppers are connected with the small synchronous wheels through auxiliary shafts. Encoders are connected with the height limiting stoppers through elasticcouplings. According to the motor and winding drum integrated lifting device structure, the production and assembly process of the permanent magnets is simplified, the deformation of the main shaft isreduced, and it is guaranteed that the motor can operate reliably.
