全电动汽车应该更加可靠，这样即使在电气传动系统发生一个或多个故障后，人们也可以继续驾驶。为此，考虑使用多相(3相以上)电机，因为其冗余特性。增加可靠性的另一种技术是用观察者取代传感器。本文研究了在无位置传感器的多相永磁同步驱动器中，以最低的焦耳损耗控制转矩的可行性，以及在一相或多相开路时的健康运行和故障运行的可行性。
All-electric vehicles should be made more reliable in such way one can continue driving even after the event of one or more faults in the electrical drive. For this, the use of multiphase (more than 3 phases) electrical machines is considered here due to its redundant feature. An additional technique to increase reliability is to replace sensors by observers. This paper studies the feasibility to control the torque in multi-phase permanent magnet synchronous drives without a position sensor, with the lowest Joule losses, and this for a healthy as well as for a faulty operation with one or more phases open-circuited.
