Hydro-Québec, TM4’s shareholder, recently made public a report comparing the complete life-cycle of an electric vehicle vs a gas-powered vehicle in the province of Québec. It makes quite clear that an electric vehicle powered by Québec’s electricity is more environmentally friendly than a conventional vehicle over their respective life cycles (including the manufacturing of components and batteries, transportation from the plant to the user, usage of the vehicle and end of life).
Ultimately, one of the key to being able to optimize the hardware design and the control software of inverters acting as motor controllers is having an in depth knowledge of the design of electric motors. It is one thing to ensure that electric motors and inverters not only have the highest possible efficiency as standalone products, but to design a truly efficient powertrain system, the challenge is keeping the combined efficiency of these components at the highest level possible.
One question our sales representatives often get is related to TM4’s multi-phase approach; what advantages do 6- and 9-phase electric powertrains provide in comparison with more traditional three-phase systems? Let’s take a look at the top 5 benefits multi-phase systems can offer.
