Embodiment Construction
[0022] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0023] A rotary transformer with a small output common ground error is composed of a stator 2 and a rotor 1, and its installation structure is sub-package or integral. The stator is composed of a stator casing 11, a stator core 16 and a stator winding 23 wound thereon, and the rotor is composed of a rotor sleeve 12, a rotor core 15 and a rotor winding 22 wound thereon. Both the stator winding and the rotor winding are electrically orthogonal A and B two-phase windings. The two-phase windings are composed of reversely connected coil groups under the two poles. The number of winding turns is proportional to the sine of the electrical angle of the number of slots. .
