摘　　要：The configuration of a brushless DC torque motor is introduced. According to the fundamental relation of the armature winding current and the air gap flux density, the ripple torque caused by the electrical errors of a resolver is approached. And a polyphase multipole resolver is developed in the brushless DC torque motor. Finally, the experimental results are presented to illustrate the improvement of ripple torque in the brushless DC torque motor with the polyphase multipole resolver.ＰｏｌｙｐｈａｓｅＭｕｌｔｉｐｏｌｅＲｅｓｏｌｖｅｒｓｆｏｒＩｍｐｒｏｖｉｎｇＲｉｐｐｌｅＴｏｒｑｕｅ￥ＳＵＮＬｉ；ＬＩＴｉｅｃａｉ；ＬＵＹｏｎｇｐｉｎｇ；ＺＨＡＮＧＺｈｉｚｈｏｎｇ（孙力，李铁才，陆永平，张志忠）（Ｄｅｐｔ．ｏｆＥｌｅｃｔｒｉｃＥｎ...
