Description
Technical field
This utility model is related to a kind of rotary transformer, and a kind of easy to manufacture, fit clearance are stable, the cylinder that reliability is high
Formula rotary transformer.
Rotary transformer is widely used between stator and rotor needs noncontact transmission signal, such as occasion of energy, video tape recorder
Magnetic drum, brushless selsyn-type electric machine, brushless synchronous machine, brushless winding-type asynchronous machine etc..
Background technology
Rotary transformer is divided into disc type, pillar by structure.
Fig. 1 is disk rotary transformer device structure schematic diagram, and the air gap between the rotor magnetic core of this rotary transformer is difficult
To keep stable, so as to cause transmission signal, energy unstable.
Fig. 2 is pillar rotating transformer structures schematic diagram, and the air gap between the rotor magnetic core of this rotary transformer holds
Easily keep stable, but outer winding is difficult to pack into outer magnetic core, causes production efficiency to reduce.
In addition, the radiating of both rotary transformers is difficult, it is difficult to adapt to large-power occasions.
Utility model content
This utility model is provided and a kind of not only can guarantee that air gap was stable, but also adapt to large-power occasions and pillar easy to manufacture
Rotary transformer.
This utility model so reaches above-mentioned purpose：Pillar rotary transformer (see accompanying drawing 3,4) include outer magnetic core 1, it is outer around
Group 2, inner magnetic core 3, interior winding 4.It is characterized in that outer magnetic core adopts combinative structure, and leaded groove 6 on inner magnetic core, inside and outside magnetic core
On leave radiating, fairlead (groove) 5.Radiating, fairlead (groove) shape in addition to long strip type, can also be other shapes.Dissipate
Heat, the position of fairlead (groove) are also not necessarily limited to form shown in the drawings.Inner magnetic core can both adopt monoblock type, it would however also be possible to employ combination
Formula.When inside and outside magnetic core adopts combinative structure, but both two-piece types, may also be three-member type.
This utility model has following advantage compared with existing rotary transformer：
1st, assembling is easily as outer magnetic core adopts combinative structure, outer winding to be easy to load outer magnetic core；
2nd, magnetic core inside and outside magnetic core easy to manufacture adopts combinative structure, and manufacture mould is simple, and high yield rate manufactures motility
Greatly；
3rd, greatly due to there is louvre (groove) on inside and outside magnetic core, the heat that winding is produced is easy to distribute for reliability height, power
Go out, thus reliability improve, power it is big.
