Motor silo In the start, the speed will suddenly become larger, and then with the stable operation of machinery, the speed will slowly stabilize, then in this process, how to control the speed of the vibration motor is one of the techniques that we operators to learn, speed control should not be easy to cause the motor burned, fire and other dangerous states,
Because the motor silo wall vibrator carrier starts slowly, the speed rise curve appears inflection point, the rise time is about 210 milliseconds, the dynamic performance is poor. The reason for analysis shows that it is difficult to obtain good dynamic performance by using such an estimated rotational speed to realize the rotational speed closed loop and magnetic field orientation of vector control, which is equivalent to introducing an inertial link into the speed feedback channel.
So when we control the speed of the vibrating motor should be in the boot use of the first moment, let the motor run slowly, and then with the increase in strength, and then make appropriate adjustments. From this, we can draw a conclusion that the smaller the speed ratio coefficient of the ZF silo wall Vibrator in the appropriate range, the better the performance of the whole system.
Conversely, the proportional coefficient is too large, there will be a large noise in the estimated rotational speed, it is difficult to obtain a good control effect by introducing such an estimated rotational speed into the speed-free vector control system.
