Patent ID: 8710829

Claim:
A sheet coil type resolver comprising: a resolver stator coil portion comprising a plurality of stator coil patterns which have a planar shape and each of which has at least one spiral coil pattern and which are disposed circumferentially on a same plane, wherein the plurality of stator coil patterns constitute a coil group of two phases having a phase difference of a mechanical angle of 90 degrees from each other; and a resolver rotor coil portion disposed to axially oppose the resolver stator coil portion with a distance therebetween; wherein the plurality of stator coil patterns are disposed such that a stator coil pattern of a first phase and a stator coil pattern of a second phase are arranged alternately on the same plane, and wherein the resolver rotor coil portion comprises a plurality of rotor coil patterns which have a planar shape and each of which has at least one spiral coil pattern, each of the rotor coil patterns have an area size corresponding to a sum area size of two adjacent stator coil patterns, and the rotor coil patterns are circumferentially connected in series to one another thereby constituting a coil group of one phase.
