[0022] See also Figure 2 The permanent magnet synchronous motor 15 is fixedly connected to the inner wall of the sealed casing 1 through the shock-absorbing mounting frame 16. This arrangement can reduce the vibration of the permanent magnet synchronous motor 15 on the sealed casing 1 when it is working through the shock-absorbing mounting frame 16, thereby preventing the sealed casing 1 from being damaged under high-frequency vibration.

[0023] See also Figure 1A vibration sensor 6 is installed on the shell of the sealed casing 1, and the vibration sensor 6 is electrically connected to the junction box 5.

The power output by the permanent magnet synchronous motor 15 is changed by the bevel gear reducer 7 to form a large torque power, which drives the rotating head 8 to rotate, and the rotating head 8 drives the stirring blades 10 to rotate to mix and stir the materials. Since the speed of the permanent magnet synchronous motor 15 under the control of the motor control chip 14 is adjustable in real time, the speed output by the bevel gear reducer 7 through the rotating head 8 has the advantages of high flexibility and good controllability, so as to adapt to various stirring process flows and achieve the optimal stirring speed, avoid waste while improving the stirring quality and achieving better energy saving effect.
