Description
Summary:•An optimized T-A formulation is proposed.•Magnetization AC losses are measured.•The magnetization AC loss is reduced by the matched Lp.•The influence of pitch length is studied. An accelerated T-A formulation based on a like-quasi-isotropic conductor, composed of a quasi-isotropic conductor and helical tapes, is developed and presented. This formulation reduces the degree of freedom of solution and is suitable for calculating of magnetization losses of large magnets. We use simulation and experiment methods to study the composition of the magnetization losses of a like-quasi-isotropic conductor and find a way to reduce the AC losses.
