Eddy Current Loss Calculation for Permanent Magnet Eddy-current Coupler
2020 7th International Conference on Information Science and Control Engineering (ICISCE), 2020This paper presents an analytical method for calculating the eddy current loss of permanent magnet eddy-current coupler (PMEC). A magnetic equivalent circuit (MEC) model considering the eddy current effect and leakage is established. Then, based on Kirchhoff’s law and Ampere’s law of loop, the flux density passing through the conductor rotor and the ...

Eddy current testing is a general term for the inspection of conductive materials using an induced electro‐magnetic field. The flow of this field is affected by the presence of defects within the material and the charges are detected by suitable instruments which reveal their location and nature.

Eddy current analysis is essential in determining the behavior of electric machines. In some classes of machinery, such as induction motors, eddy currents are responsible for producing the main torque. In other situations an analysis of eddy currents is necessary to find losses, resistance and reactance (see chapter 5).

The eddy current method of non-destructive testing, as currently practised, was pioneered by Friedrich Forster in the 1940s, and there has since been rapid progress in its development. Eddy current tests can be made on all materials which are electrically conducting.

The eddy current non-destructive inspection technique can be used effectively on fibre metal laminates. It uses the principle of electromagnetic induction, i.e. the interaction between a magnetic field with an electrically conductive object. With this method, the different Fibre Metal Laminate types can be easily discriminated and fatigue cracks in the

The scope of eddy current testing is summarized in section 4.1. But with few exceptions the use of eddy currents is restricted to testing samples made either wholly or partly from metal and then only for regions at or just below the surface. However, the technique has the distinct advantage that no contact with the object under test is required and ...

<div class="htmlview paragraph">Even though friction brakes are very necessary, they have certain limitations as to heat capacity that is especially noticeable on hills, but is also a factor in congested fast moving traffic. A 45,000 lb tractor and semi will generate about 300 hp going down an 8% grade at about 45 mph and less than one third of ...
