93% of EVs bought in 2018 used everlasting magnet traction motors

Analysis agency Adamas Intelligence has reported that 93 p.c of all passenger EVs bought in 2018 used everlasting magnet (PM) traction motors, a rise of 1 p.c from 2017. PM traction motors use neodymium iron boron (NdFeB) everlasting magnets within the rotor, which spin the rotor in response to a rotating magnet subject produced within the stator. In response to Adamas, PM traction motors can present as much as 15 p.c extra effectivity than induction motors, and are essentially the most power-dense kind of traction motor accessible. “Trying forward, we anticipate demand for PM traction motors, and the uncommon earth magnets they comprise, to proceed on a path of explosive development as EV demand soars and the sales-weighted common motor energy (kW) per EV continues to rise,” acknowledged Adamas.   SEE ALSO: Tesla’s prime motor engineer talks about designing a everlasting magnet machine for Mannequin three   Supply: Adamas Intelligence
