摘要：

The paper presents numerical and experimental study of the eddy current brakes, used to produce braking torque of a medical bike. Complex structure and lack of symmetry plane parallel geometry required the development of 3D numerical models to calculate the magnetic field. They allow determination of overall brake performance and design optimization to increase braking torque and to reduce volume. 3D numerical models developed on the basis of finite element method are models of transient magnetic system for determining induced currents in the disk. In solving problems field, it was used the formula T Phi-Phi r. Thus in the region of the disk were used electric vector potential T and total magnetic scalar potential Phi, in regions of the core magnetic total scalar magnetic potential Phi, and in areas of air forms in Phi r reduced scalar magnetic potential.
