    • A velocity control apparatus of a motor is provided to compare velocity instruction values with velocity estimation values in every equal part, and to compensate for velocity errors in accordance with load characteristics, thereby reducing vibrations and noise caused by the load characteristics. A velocity compensator(100) compares velocity instruction values with velocity estimation values of previous steps, operates velocity errors of the previous steps based on the compared results, and determines velocity compensation values for compensating for the velocity errors to output the determined compensation values. A comparator(200) compares the velocity compensation values with a current velocity estimation value, and outputs a torque current instruction value.
    • 提供电动机的速度控制装置,用于将速度指令值与每个相等部分的速度估计值进行比较,并根据负载特性补偿速度误差,从而减少由负载特性引起的振动和噪声。 速度补偿器(100)将速度指令值与先前步骤的速度估计值进行比较,基于比较结果来操作先前步骤的速度误差,并且确定用于补偿速度误差的速度补偿值以输出所确定的补偿值。 比较器(200)将速度补偿值与当前速度估计值进行比较,并输出转矩电流指令值。
