Abstract
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.

A torque index sensor, comprising:
- 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.
A torque index sensor, comprising:
- a rotor rotating with the first shaft which is one of an input shaft and an output shaft and having a first magnet on an outer circumferential surface thereof;
- a tooth disposed to be spaced apart from an outer side of the first magnet;
- a molding member inserted into the tooth to fix the tooth, having a lower side combined with an outer circumferential surface of a holder, and having a ring-shaped groove formed on a lower surface thereof;
- and
- a second magnet disposed in the groove,
- wherein a ring-shaped shielding member is disposed between the groove and an upper surface of the second magnet.
