|Applicants:||JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITED
HONDA MOTOR CO., LTD.
|Title:||BRUSHLESS RESOLVER AND ROTATION ANGLE DETECTING DEVICE|
A brushless resolver, which is provided with a rotor that is provided with a single-phase excitation coil, and a stator that is provided with a dual-phase detection coil, the rotor being attached to the shaft of a motor and the rotation angle of the motor being detected, wherein an induction coil is wound around the shaft. The induction coil is connected to the excitation coil, and electromotive force induced by the induction coil via changes in the magnetic flux of the motor flowing in the shaft is used as a excitation signal supplied to the exciting coil.
