Patent ID: 7605512

Claim:
A method of designing a reluctance resolver, the resolver comprising a stator and a rotor, and an exciting coil and two sets of outputting wires wind around the tooth portion of the stator, the designing method comprising the following steps of: fixing relative position: determining a teeth number ratio between the stator and the rotor of the resolver, fixing the phase angle of the tooth portion of the stator and the rotor; calculating the turn ratio of the stator: calculating the turn ratio of the tooth portion of the stator by substituting the phase angle of the stator and the rotor into sine and cosine functions; winding the coil of the stator: winding the coil around the tooth portion of the stator according to the calculated number of turns of the tooth portion of the stator; and designing resolver: designing the resolver according to the calculated structures of the stator and the rotor of the previous steps.
