This device causes less magnetic leakage while the manufacturing cost is low.
How Is Magnetic Leakage Reduced Within a Transformer?
The present invention relates to a nondestructive sensor for detecting magnetic leakage and a manufacturing method thereof.
Also, the magnetic leakage fields no longer have an influence on the sensor device such that measuring precision is increased.
Magnetic leakage fluxes caused by defects in the inside or on the surface of the material (10) are sensed by the magnetic sensor (7a).
Thus, it is possible to make the magnetic flux leaking to the brake rotor (3) during brake OFF substantially zero.
There is provided an eddy-current reduction gear capable of assuring brake capacity and preventing magnetic leak.
In this model one affirms that the magnetic escapes do not exist for the primary winding.
In this model one affirms that the magnetic escapes do not exist for the secondary winding.
In this model one affirms that the magnetic escapes do not exist for the secondary winding.
In this model one affirms that the magnetic escapes do not exist for the primary winding.
The invention further includes a magnetic expander configured to guide the magnetic flux and to prevent flux from escaping, said expander being disposed on an internal surface of the yoke of the rotor.
