    • If there is static friction, the magnetic pole position estimation is completed at the time when error torque used for magnetic pole position estimation becomes less than the friction, so that there remains magnetic pole error. A problem has been that when the error torque becomes less than a forward static friction, there remains a positive magnetic pole deviation and when the error torque becomes less than a backward static friction, there remains a negative magnetic pole deviation. By shifting in the negative direction and the positive direction initial values for estimating a magnetic pole error in operation sets, a true pole-error estimation value is estimated in the use of a pole-error estimation value having a positive magnetic pole error obtained by the positive shift operation and a negative one obtained by the negative shift operation, which can reduce estimation error due to the static friction.
    • 如果存在静摩擦,磁极位置估计在用于磁极位置估计的误差转矩小于摩擦时完成磁极位置估计,从而保持磁极误差。 一个问题是,当误差转矩小于正向静摩擦时,仍然存在正磁极偏移,当误差转矩小于反向静摩擦时,仍然存在负磁极偏差。 通过在负方向和正方向上移动用于估计操作组中的磁极误差的初始值,在使用由具有正磁极误差的极性误差估计值得到的极性误差估计值时,估计真正的极点误差估计值 正移位操作和通过负移位操作获得的负移动操作,这可以减少由于静摩擦引起的估计误差。
