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; ...

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...

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 ...

Towards the end of July I read a post about how efficient AC induction motors are and that how using them and reducing their speed will help us all to reduce the green-house effect, save money and the ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
