发明名称 Torque index sensor
摘要 A torque index sensor according to an embodiment of the present invention includes a rotor rotating with the first shaft which is one of an input shaft and an output shaft having a first magnet on an outer circumferential surface thereof, a stator disposed on an outer side of the first magnet and rotating with the second shaft which is the other of the input shaft and the output shaft, a shield disposed on a lower side of the stator and rotating with the second shaft and a second magnet combined with a lower side of the shield and rotating with the second shaft. The torque index sensor shields magnetic field interference and improves operational reliability.
