Note that this error is not a pure sine, it also has some harmonics with corresponding periods of 1/100 revolution and 1/50 revolution.
Note that this error is not a pure sine, it also has some harmonics.
One way to reduce these errors is to use a ball-screw mechanism with a smaller pitch.
The price to pay is smaller velocity.
One way to reduce these errors is to use a ball-screw mechanism with a smaller pitch (or a reduction gearbox).
The price to pay is smaller velocity (and even high vibration frequencies for the same velocity).
