Abstract:
The finite element method was employed to calculate the magnetic fields and losses of step-lap laminated transformer cores. The effect of step-lap form on laminated iron loss was investigated numerically by using a new criterion. The research indicates that rational choice of the laminated step and the flux density in iron core can reduce the no-load loss furthest. Compared with the lamination with one piece only, the loss of lamination with two or three pieces will undoubtedly increase, however, the increase rate will be lower with raising the laminated step number. Therefore, two or three pieces for each lamination is a better choice for higher lamination step, and in this case working hours can be significantly saved without obvious increase in loss.
