PURPOSE:To increase the inside diameter of an armature, and to elevate torque by executing two-layer lap winding to a slot for an armature core while disposing a control detection section into a rotor section. CONSTITUTION:A slot 18 formed to an armature core 1 is shaped in a shallow groove into which only the lower coil side 19 of a coil can be buried. The number of the slots is brought to the same number as the total coil number NC=3qP (q represents an integer) of a winding 2. The lower coil sides 19 of each coil are buried into the slots 18, and upper coil sides 20 are fixed and arranged onto the inner circumferential surface of an armature in an air gap section between the inner circumferential surface of the armature core 1 and the outer circumferential surface of a field permanent magnet 3. The number N of the slots for the armature is set so that the three-phase winding 2 of two-layer lap winding fitted to the conditions of 3/2P<N<3P is executed. A rotor yoke 4 is formed to a cuppy shape, and a control detector consisting of a resolver stator 12, a resolver rotor 13, a rotary transformer stator 14 and a rotary transformer rotor 15 is disposed into the internal space of the cup.
