For a motor, there are two sources of vibration, one being an electric field and one being a magnetic field. The principle of motor motion is that the output shaft of the motor is finally rotated by driving the magnetic field to rotate by using an electric field, so when the volume of a magnetic body is fixed and the material is fixed, the final performance is fixed, and the vibration can be reduced only by reducing the force of the electric field. There are generally two methods to reduce the electric field force: one is to increase the resistance and the other is to decrease the magnetic conductive area. For a particular application, the resistance generally cannot be altered; only the magnetic conductive area can be reduced.

In this embodiment, through setting up tapered slot 6, and then increase the magnetic field clearance of water conservancy diversion, through the effective magnetic flux of radial air gap, required effort is little, and simple structure is compact, and it is convenient to adjust, and required regulation space is little.
