They test three different magnets and measure the distance that each magnet is able to attract a paper clip. To make the test fair, they use the same ruler and paper clip throughout.

Low-speed high-torque permanent magnet synchronous machines (PMSMs) are widely used in heavy industrial production, whereas the bulky prototype size poses challenges for assembly. This article ...

This article provides an overview of current noise vibration and harshness (NVH) challenges for the design of permanent magnet synchronous motors (PMSMs) for automotive applications. Particular ...
