Title:
ROTATION STATE DETECTING DEVICE
Document Type and Number:
Japanese Patent JP2012202791
Kind Code:
A
Abstract:
To provide a rotation state detecting device capable of detecting both of torque and the number of rotations without increasing the number of components.
A rotation state detecting device includes electric signal detecting means for detecting an electric signal corresponding to the strain amount of a member deformed by torque acted on a rotor; and rotation state detecting means for calculating the torque acted on the rotor from the amplitude of the electric signal detected by the electric signal detecting means, and calculating the number of rotations of the rotor on the basis of a fluctuation period of the electric signal.
