Rotary Coils
Special rotary coils create a strong low frequency rotating magnetic field within the passage zone (in connection with low frequency generator EG2422R). Its special application is the degaussing of ring-shaped work pieces (e.g. tubular springs, piston rings) already packed in stacks.
The magnetic field penetrates the work pieces vertically, and rotates inside the individual parts. When guiding the ring stack slowly through the coil, each individual ring is optimal demagnetized without creating residual magnetism at the touching points. To assure a precise guiding through the coil, a centering device is recommended.
In order to assure successful degaussing, it is recommended that the distance between work piece and inner cladding of the passage is kept at a minimum. Therefore, we offer only customized solutions.
