Abstract
This paper investigates the behavior of a vector-controlled fault-tolerant permanent magnet motor drive system adopting a vertically placed strip winding (VSW) which can limit interturn short-circuit (SC) fault current to its rated value regardless of the position in the slot containing the shorted turns. The drives' dynamic behavior is simulated using a per-phase equivalent circuit model, with the winding inductances and resistances analytically calculated based on the machine geometry and fault location. A simplified thermal model is also grafted into the system model to effectively simulate the dynamic behavior of the machine during healthy interturn SC fault and postfault controlled scenarios. The SC-fault-current-limiting capability, the additional losses, and the thermal behavior of the winding are studied and compared with conventional winding adopting round conductor winding. The proposed winding design is verified with finite-element analysis and is then validated experimentally. Results show that the VSW inherently limits the SC current, reduces its dependence on the position of the fault within the slot, but results in an increase in ac losses. © 1982-2012 IEEE.
