Nowadays, automobile transportation is in a crisis due to the high price of gasoline and, in the future, the crises will worsen unprecedentedly. Hence, researches are oriented toward hybrid electric vehicles being a good alternative of conventional vehicles. Thus, assuring the health and proper operation of HEVs is a mission. This paper focus on the importance of HEV's permanent magnet machine fault identification where a survey of the different types of fault that may arise is illustrated, relating it to the useful parameters that should be measured and checked to detect the presence of each type of fault. The faults are classified according to their level of severity; a case study is conducted where it is shown that demagnetization of magnet is the most sever fault taking into consideration the relative cost of magnet and the occurrence percentage of demagnetization. Index Terms -Hybrid electric vehicle, permanent magnet machine, Faults.

“…In [30], three topologies are stated: V-shape IPM, W-shape IPM and segmented IPM. A finite element analysis is investigated where it is concluded that W-shape interior permanent magnet topology is the most suitable for electric vehicle applications due to its good flux-weakening performance and wide constant-power operating range.…”

“…Bianco et al [5] investigate the possible incendive effect due to partial discharges in the insulation system. Dymond [4,61 indicated that contamination will lead to surface discharge and tracking on the windings, which is another potential source of sparking and arcing. Hamer et al [7] elaborated on the relationship between hot rotor surfaces and flammable vapor ignition.…”

Electrical machines are used widely in the petrochemical industry. Most of the machines are operated in Class I hazardous locations and hence appropriate precautions must be taken to protect the machine to ensure that the explosive atmosphere cannot be ignited. There are four types of protection applicable to large machines. They are type p (purged and pressurized), type e (increased safety), type d (flameproof) and type N. Type p, type e and type d protections are permitted in Zone l o r Zone 2. In 1996 and 1999, two machines were designed and tested to meet IEC 60079-0 and 60079-7 standards regarding Exe II B 200°C ( T3 ) requirement. The machines are installed in Zone 2 locations. The paper will present the electrical and mechanical design consideration of the increased safety induction machine. Finally, the paper describes the test procedure and summarizes the results from the series of tests performed on these two machines.
