“…Inverter faults are the focus of the majority of PMSM fault research. Several studies have been conducted on the use of inverters with an additional phase or neutral leg and a subsequent hardware configuration that increases complexity, size, and cost [12]. Furthermore, the neutral point of the machine must be accessible [13].…”

Electromagnets have traditionally been used in all drives. Because they take up space, the size of the machine grows in tandem with increased torque and it’s rating thereby lowering its energy efficiency. If the rotor winding is replaced with permanent magnets, the motor will reverse. The recent improvement of magnetic materials resulted in a reduction in motor size and more effective use of redial space. Permanent Magnet Synchronous Motors (PMSM) have a high-power factor, are extremely durable, and require almost no maintenance. Such motors can be designed with power ranging from a few watts to a few kilowatts for applications ranging from fans to alternators including electric vehicles. This need reliable and safe operation of drives which would be fault tolerant. The study compares fault tolerant controllers using Direct Torque Control (DTC), and Fuzzy Logic Control (FLC) of PMSM for stator fault. Simulations are performed for different voltages and loads under fault. DTC selects voltage vectors using a hysteresis controller which gives better speed regulation but increases torque ripple requiring an accurate mathematical model. The use of FLC gives similar performance by precise voltage vector selection without needing an accurate mathematical model but has lower speed regulation. The results of DTC and FLC are show that even with failure of stator winding the motor can function satisfactorily
