Abstract
A cant angle sensor comprises a conductive, nonmagnetic pendulum suspended from the shaft of a resolver for limited angular travel in the slot of a C-shaped magnet. When the angle of the sensor changes, the pendulum seeks a new vertical null, and the C-shaped magnet exerts a viscous hystersis damping force causing the pendulum to quickly come to rest without oscillation. The rotor magnet wire of the resolver is connected directly to output terminals to avoid friction due to brush contact on the rotor shaft.
