Description
Technical field
The present invention relates to a kind of large capacity rotating transformer structures, belong to large capacity resolver equipment technical field.
Background technology
Resolver is the signal element that a kind of output voltage changes with angle of rotor.When excitation winding is during with the alternating voltage excitation of certain frequency, the voltage magnitude of output winding is just becoming with angle of rotor, cosine function variation, or keeps a certain proportionate relationship, or linear with corner in angle range necessarily.It is mainly used in coordinate transform, triangulo operation and angle-data transmission, also can be used as two-phase phase shifter and is used in angle-digital switching device.
Tradition resolver consists of rotor and stator winding, and both are separate, once with secondary coil all on stator, general rotor differs 90 degree coils by two groups and forms, and adopts brushless design.Be subject to structural limitations, so the capacity of general resolver is little.
Summary of the invention
The object of the invention is to provide a kind of large capacity rotating transformer structures, and simple in structure, resolver capacity is large, solves the problem existing in background technology.
Technical scheme of the present invention is:
A kind of large capacity rotating transformer structures, on the stator of motor and rotor, be respectively equipped with three phase windings, in large capacity resolver, be also provided with motor driven systems and collector system, three-phase rotor winding is connected with collector system respectively with stator bus, described motor driven systems drives rotor and stator, and large capacity resolver be take main drive shaft as axle Central Symmetry layout.
Described large capacity resolver is provided with outside resolver unshakable in one's determination along main drive shaft outside.
By given primary and secondary line, add electric current and make stator winding have alternating current, thereby produce excitation in iron core, make to respond in rotor winding corresponding electric current.By motor driven systems, regulate the position of the suitable stator of rotor, so just can control direction and angle by resolver power, by the signal pickup assembly of each position, signal is delivered to collector system by signal cable, and collector system is collected the electric current between conduction three-phase rotor winding and stator bus.
The invention has the beneficial effects as follows: can regulate rotor with respect to the position of stator, control by direction and the angle of resolver power, the electric current between conduction three-phase rotor winding and stator bus, simple in structure, resolver capacity is large.
