Torque-speed characteristics are obtained for different values of switching frequency to demonstrate its effect on the linearity of the characteristic. The proposed simulation model is developed as a part of a software laboratory to support and enhance undergraduate electric machinery courses at Nigde University, Nigde, Turkey.eninfo:eu-repo/semantics/closedAccessConference Object10.1109/UPEC.2008.46516402-s2.0-68949206339N/A
