New structure of printed winding motor

The utility model has the essential technical proposal that a printed winding motor composed of a permanent magnetism stator, a printed winding rotor, an axletree and a front and a back end covers, and an output shaft is a hollow shaft. A supporting shaft (1) is connected with the hollow shaft (3) through the axletree (2). The hollow shaft (3) integrates an axletree chamber and a bracket into a piece. The printed winding rotor (4) is fixed to the hollow shaft (3). The utility model has advantages that firstly, the supporting shaft is inserted in the output shaft, and the motor is easy to be arranged in the central position of a mechanism device rotating around a fixed shaft to carry out the drive, such as a bicycle wheel, a hoister, etc.; secondly the utility model has the advantages of simple structure, compactness and few parts; thirdly, the utility model runs stably, is easy to ensure the concentricity, is not easy to suffer the influence of the radial force, and the lifespan of the motor is extended.
