Problems solved by technology

When the motor is working, when the motor power is large, the motor shaft will generate a large torque. Since the motor shaft is hollow and long in length, the large torque will deform the motor shaft and affect the gap between parts, making it The increased resistance of the movement will affect the stability of the motor operation, and it is easy to generate noise. In severe cases, it cannot work at all
If multiple stator cores and windings are installed on the motor shaft of the drum motor, the force on the motor shaft will be more uneven

Embodiment 1

[0025] See figure 1 , a drum motor, including a cylinder 1, a driving shaft 2, a driven shaft 3, a stator core 4, a stator winding 5 and a rotor magnet 6. The cylinder body 1 is a cylindrical iron cylinder, and the driving shaft 2 and the driven shaft 3 are arranged along the axis direction of the cylinder body 1 and are respectively rotatably connected to two ends of the cylinder body 1 . Both the end of the driving shaft 2 away from the driven shaft 3 and the end of the driven shaft 3 away from the driving shaft 2 extend out of the cylinder 1 . The stator core 4 is sheathed and fixed on the driving shaft 2 , and the stator winding 5 is installed on the stator core 4 . The slots on the stator core 4 are inclined slots. The rotor magnetic steel 6 is fixed on the inner wall of the cylinder 1 and the position of the rotor magnetic steel 6 corresponds to the stator core 4 .

[0026] The driving shaft 2 is a hollow shaft, and the driven shaft 3 is a solid shaft. Both ends of t...

Embodiment 2

[0030] See figure 2 , the drum motor of this embodiment, the rest is the same as that of Embodiment 1, the difference is that: the driving shaft 2 and the driven shaft 3 are both hollow shafts, and the first cable 71 passes through the side hole 21 at the left end of the driving shaft 2 to Inside the driving shaft 2 and from the left end of the driving shaft 2, the second cable 72 passes through the side hole 21 at the right end of the driving shaft 2 into the driving shaft 2, and then into the driven shaft 3, from the The right end goes out.

[0031] The drum motor of this embodiment also includes a driven end cover 91 and a driving end cover 92 respectively plugged and fixed on one end of the cylinder body 1, and the two ends of the driven shaft 3 are respectively rotatably connected to the driven end cover 91 through corresponding bearings. One end of the drive shaft 2 protruding from the cylinder 1 is rotationally connected with the drive end cover 92 through a bearing. ...

Embodiment 3

[0034] See image 3 , the rest of the drum motor of this embodiment is the same as that of Embodiment 2, except that: the limit bearing seat 84 is provided with a limit retaining ring portion 841 extending to the rotor magnetic steel 6 .

Abstract

The invention discloses a roller motor. The motor comprises a cylinder body, a driving shaft, a driven shaft, a stator core, a stator winding and rotor magnetic steel. The cylinder body is a cylindrical iron cylinder; the driving shaft and the driven shaft are arranged in the axis direction of the cylinder body and rotationally connected to the two ends of the cylinder body correspondingly. The end, away from the driven shaft, of the driving shaft and the end, away from the driving shaft, of the driven shaft extend out of the cylinder body, the stator iron core is fixedly arranged on the driving shaft in a sleeving mode, the stator winding is installed on the stator iron core, the rotor magnetic steel is fixed to the inner wall of the cylinder body, and the position of the rotor magnetic steel corresponds to that of the stator iron core. The length of the roller motor is not limited, the operation resistance is small, and the stability is good.
