Description

Embedded rotating electromagnetic coupler
Technical field:
The utility model relates to embedded rotating electromagnetic coupler.
Background technology:
Transmission performance based on the non-contact type electric energy transmission system of electromagnetic induction principle mainly restricts coupling ability and stability in electromagnetic coupler.At present, the coupler that generally uses is bigger owing to parameters such as coupling coefficient are influenced by structural factor, and not only coupling coefficient is low, and poor stability, is unfavorable for the stability and high efficiency transmission of system.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of embedded rotating electromagnetic coupler is provided; Primary coil is embedded in the secondary coil; Not only strengthened the coupled relation between the coil, and it is little to make coupling coefficient influenced by structural change, system obtains stable transmission performance.
The technological solution of the utility model is following:
The utility model discloses a kind of embedded rotating electromagnetic coupler; It is made up of elementary magnetic core, primary coil skeleton, primary coil, secondary magnetic core, secondary coil skeleton, secondary coil; Primary coil is wound on the primary coil skeleton, and the coaxial primary magnetic in-core that is installed in; Secondary coil is wound on the secondary coil skeleton, and coaxial being installed in the secondary magnetic core.
Said elementary magnetic core is a jar type magnetic core, and column diameter equates with primary coil skeleton diameter of bore in it.The primary coil skeleton is made with nylon.
Said secondary magnetic core is a jar type magnetic core, and its inner diameter equates with primary coil skeleton external profile diameter.The secondary coil skeleton is made with nylon.
Said primary coil skeleton is a cylinder barrel shaped, and an end has end plate, and diameter equates that with elementary magnetic core leg internal diameter the tubular internal diameter equates with primary magnetic in-core column diameter.
Said secondary coil skeleton is a cylinder barrel shaped, and an end has long end plate, and the other end has short end plate, and long end plate equates that with secondary magnetic core leg internal diameter short end plate diameter is less than long end plate.The tubular internal diameter is bigger than primary coil skeleton.
Said elementary magnetic core and secondary magnetic core are selected the jar type magnetic core of same model for use.
Operation principle: primary coil and secondary coil are wound on the corresponding skeleton, form coaxial configuration with two magnetic cores; After two coil electricities, the magnetic field of formation is coupled through the closed magnetic circuit that magnetic core and gap form.Because primary coil embeds in the secondary coil, its excitation field is most of closed through Coupled Magnetic, will inevitably pass secondary coil; Make that two coil coupling coefficients are higher; And in the rotary course, the change of coil relative position is little to the degree of coupling influence, and system transmissions stability is high.
The beneficial effect of the utility model is:
1, primary coil is embedded within the secondary coil, and the magnetic field degree of coupling is high, and system can obtain higher transmittability.
2, primary coil is embedded within the secondary coil, off-centre takes place in the rotary course can not produce big change to Coupled Magnetic, and parametric stabilities such as system, coupled coefficient, inductance are high, and system can obtain advantages of higher stability.
