  • Device and method for measuring pitch and roll torques
    Patent number: 9697866
    Abstract: Embodiments of the invention provide a device for measuring pitch and roll torques. The device comprises a sensor plate having a horizontal cross member, a vertical cross member and a surrounding member connecting ends of the horizontal and vertical cross members, wherein the horizontal cross member and the vertical cross member intersect each other at a centre region of the sensor plate; a VCM coil attached to the sensor plate and configured to generate a pitch and a roll torque when an electrical current is applied to the VCM coil; a first strain gauge attached to a surface of the horizontal cross member and configured to detect a horizontal strain caused by the pitch and roll torques; and a second strain gauge attached to a surface of the vertical cross member and configured to detect a vertical strain caused by the pitch and roll torques.
