Abstract

A new inductance measurement method for permanent magnet synchronous linear motor is proposed in this paper. Through the theoretical analysis, the relational expression between d- and q-axis inductance and the line voltage is derived. Therefore, we can obtain the accurate inductance value only by measuring the basic electrical parameters at two special mover positions. Compared with conventional inductance measurement methods, the proposed method has the advantages of easy to implement, less measured parameters, high compatibility and so on. In order to verify the inductance measurement results, the finite element method is adopted as a reference model.
