一种旋转变压器系统和具有这种旋转变压器系统的旋转体
摘要：
本发明提出了一种旋转变压器系统和具有这种旋转变压器系统的旋转体。该旋转变压器系统包括至少两个旋转变压器，至少包括第一旋转变压器和第二旋转变压器；每个旋转变压器均包括定子和转子，定子包括定子检测齿，转子包括转子凸极；每个旋转变压器均包括绕在定子检测齿上的多个线圈，各线圈的电感随着对应的转子的旋转角度的改变而改变；第一旋转变压器的转子包括且仅包括1个转子凸极；第二旋转变压器的转子包括2个或2个以上的转子凸极；至少第一旋转变压器的转子和第二旋转变压器的转子设置为同步转动。该旋转体还包括旋转体本体；旋转变压器系统的旋转角度与旋转体本体的旋转角度成规则的关系。本发明大大提高了转子的绝对位置测量精度。
摘要（英）：

The invention provides rotary transformer system and a rotator with rotary transformer system. The system comprises at least two rotary transformers at least comprising a first rotary transformer and a second rotary transformer. Each rotary transformer comprises a stator and a rotor. The stator comprises stator detecting teeth. The rotor comprises a rotor salient pole. Each rotary transformer comprises a plurality of coils which are wound around stator detecting teeth. The inductance of coils changes with the changing of rotation angle of the corresponding rotor . The rotor of the first rotary transformer only comprises one rotor salient pole. The rotor of the second rotary transformer comprises two or more than two rotor salient poles. At least the rotor of the first rotary transformer and the rotor of the second rotary transformer rotate synchronously. The rotator also comprises a rotator body. The rotation angle of rotary transformer system and the rotation angle of rotator body form regular relations. The system greatly improves the absolute position measurement accuracy of the rotor.
