Electric vehicle production scaling would not be possible with all the scarce and expensive materials used today. A 17-year-old boy has a solution to the problem, designing an electric motor that ...

The global market for Electric Motor Core was valued at USD 16490 Million in the year 2024 and is projected to reach a revised size of USD 26580 Million by 2031, growing at a CAGR of 7.2% during the ...

It’s the 2022 Regeneron International Science and Engineering Fair. A boy has entered a machine into the fair that, upon closer inspection, isn’t just your basic-bones engine; it’s a synchronous ...

The transmission for most vehicles can be configured according to the scheme presented here. Such a transmission may be ...

Electric motors usually comprise a stator and a rotor, with the latter rotating inside the former. Donut Lab thinks this design is outdated, and a hollowed-out rotor can offer important advantages.

Permanent magnet synchronous motors (PMSMs) are AC synchronous motors that receive field excitation by permanent magnets. These motors have sinusoidal back-EMF and are similar to brushless DC (BLDC) ...

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...
