Hamid A. Toliyat’s pioneering development of multiphase induction motors has provided industry with more reliable and efficient power alternatives for transportation applications. His cutting-edge work on fault-tolerant five-phase motors during the late 1980s improved on traditional three-phase motors. He demonstrated that multiphase motors can produce more than a 15% improvement in torque while using the same amount of copper and iron as in three-phase machines. Multiphase machines are also more fault tolerant, resulting in more reliable operation. Prof. Toliyat also extended his work to synchronous and permanent magnet motors, realizing the same benefits. His contributions are integral to today’s electric motor applications for aircraft, electric and hybrid vehicles, and electric ship propulsion.

An IEEE Fellow, Prof. Toliyat is a professor and the director of the Electric Power and Electronics Program at Texas A&M University, College Station, TX, USA. Toliyat was the recipient of the 2014 IEEE Nikola Tesla Award.
