Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

This paper mainly proposes an improved advanced angle field weakening control strategy for multi-phase PMSM. Firstly, voltage vector reference limit of multi-phase PMSM is analyzed and calculated.

A recent study led by NASA has revealed a surprising connection between Earth’s magnetic field and the oxygen levels that ...

The transient field-frequency domain of magnetic dipole in a two-layered conducting Earth has been studied. It is obtained as a summation of waveguide modes plus contributions from branch cuts in the ...
