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. |

1. A torque index sensor, comprising:
a rotor rotating with a 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 a 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; wherein the shield comprises:
a ring-shaped shielding member having a lower side combined with the second magnet; anda support protruding from the lower side of the shielding member and supporting the second magnet; and wherein the ring-shaped shielding member is disposed on an upper surface of the second magnet and a lateral side surface of the second magnet. |
