Speed volatility is affected by the following factors

Speed volatility is affected by the following factors

encoder feedback

(1) The encoder's limited resolution and velocity loop period (the lower the resolution, the longer the cycle time, the greater the speed fluctuation).

encoder feedback

(2) Poor encoder installation can cause low frequency periodic fluctuations in the encoder feedback.

encoder's limited resolution

(3) The cogging torque fluctuation of the servo motor also causes low-frequency periodic fluctuations under the speed loop.
