An electric vehicle motor rotational speed value generating device comprises: a first counter counting an input frequency according to a system frequency and outputs a first bit numerical value; a second counter receiving the first bit numerical value, the second counter counts the first bit numerical value with an exponent n in a 2n exponential function that approximates a maximum rotational speed command value and outputs a second bit numerical value; a frequency divider receiving the second bit numerical value, and the frequency divider divides the second bit numerical value from the system frequency and outputs a counting frequency; and a third counter receiving the counting frequency, and the third counter is electrically connected to a maximum frequency generator and receives a maximum frequency generated by the maximum frequency generator, and the third counter counts the maximum frequency from the counting frequency and outputs a feedback rotational speed value.
