Inductance is an important parameter of PMSM due to its direct impact on the dynamic performance, especially on the precise control of the system. In this paper, a novel calculation method for the incremental inductance of motor winding is adopted, and a data processing technique is presented. Nonlinear incremental inductance of the motor winding was tested with the dynamic hysteresis loop method...
In this paper the influence of axial length ratio of stator segment on performance of tubular transverse flux linear machine (TTFLM) is investigated. The following issues have been emphasized: cogging force, winding flux, and back-EMF. The special topology of TTFLM requires 3-D finite element analysis to accurately predict the machine performance. However, equivalent 2-D finite element analysis is...
Inductance is an important parameter which affects the PMSM dynamic performance as well as the controlling effect. As prodigious indeterminacy lie in winding nonlinear incremental inductances during motor operating, and more attention are paid to the rule of currents variety in the winding, so its accurate measurement is a key issue to PMSM. The dynamic magnetic hysteresis loop method to test winding...
