Recent patent disclosures indicate that BYD has strengthened its work on variable-flux permanent-magnet synchronous ...

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 ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...

Why EV manufacturers are working toward eliminating rare-earth materials from their motors. An introduction to the wound-rotor synchronous motor (WRSM) architecture, and some of its innovative ...

Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor. Now, Tesla’s principal motor ...
