Claims

[Claims for Utility Model Registration] 1. At least two primary coils constituting the primary side of a rotating transformer are provided, the first primary coil being connected to an AC power source, and the second secondary coil being connected to an AC power source. The coil includes a stator connected to a servo signal source via a modulation means, and at least two secondary coils corresponding to each of the secondary coils forming a secondary side of the rotary transformer,
A first secondary coil corresponding to the first primary coil is connected to rotation control means for the armature coil via a rectifying means, and a second secondary coil corresponding to the second primary coil is connected to rotation control means for the armature coil through a rectifying means. A brushless motor comprising a rotor, the coil being connected to the rotation control means via a demodulation means, and the rotation control means being connected to an armature coil. 2 Scope of utility model registration claim No. 1: The rotor is ironless.
Brushless motor as described in the section.
