The interior permanent magnet motors have higher output power but more magnetic leakage flux.
Metal magnetic memory theory has proved that the maximum variation of scattered magnetic leakage field [H.sub.p] occurs in stress concentration and deformation zone; that is, the tangential component of magnetic leakage [H.sub.p](x) shows the maximum value while normal component of the magnetic leakage [H.sub.p] (y) is shown to be zero (Figure 1).
3(a), there is little magnetic leakage flux out of the soft iron, and the magnetic flux density is gathered in the air gap on the ends of the device, which improves the adhesion force.
In this study, the optimal design model of detector based on magnetic leakage flux (MLF) carried by robot for detecting broken steel strands in ACSR cables has been proposed.
Subjects include: fundamentals of electromagnetism and magnetic particles, fundamentals of magnetic testing, magnetic leakage field measurements, equipment used in magnetic testing, reference standards, demagnetization, metals testing, electric power applications of magnetic particle testing, magnetic testing of metals, infrastructure and aerospace applications, and chemical and petroleum applications.
Applications include the convergence of contactless ID (RFID), credit cards and cellular telephones where magnetic leakage from dynamic speakers poses a serious risk of data error or loss.
To focus the magnetic flux at the gate and restrain the decrease of magnetic flux, the magnetic circuit must be insulated from the mold to prevent magnetic leakage. For this purpose, the magnetic core was supported using nonmagnetic metal, and the gate and cavity were also made of non-magnetic metal.
The new actuator has the added advantage of very low magnetic leakage, allowing actuators to be used in close proximity to one another without performance degradation.
The magnets produce a magnetic flux (or field) in the pipe wall, and sensors measure the magnetic leakage (changes in the magnetic field) at zones where the pipe wall thickness is not uniform.
The new optimized systems will include radiography, ultrasound, magnetic leakage, etc.
The change of coil location has an effect on the magnetic leakage flux of two spaces.
The magnets produce a magnetic flux or field in the pipe wall and sensors measure the magnetic leakage at zones where the pipe wall thickness is not uniform.
