Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms.

Magnetic oil droplets with switchable rolling and swimming modes enable adaptive navigation, particle transport, and control ...

When summer comes knocking hard, an air cooler is like a part of your everyday life. It’s the cost-effective version of air conditioning, cooling you down without breaking the bank on your electricity ...

Three-phase AC induction motors are designed to operate on three separate electric currents, ... In an induction motor, the current in the stator windings generates a rotating magnetic field, ...

The magnetic flux density, angular frequency and rotation axis can be modulated by tuning the amplitude and frequency of each phase current. The device can achieve a rotating magnetic field with ...

Finally, three-phase systems can produce a magnetic field that rotates in a specified direction, which simplifies the design of electric motors. Three is the lowest phase order to exhibit all of ...

Technically speaking, the motor control must be based on torque and magnetic flux, so we are able to control the torque accurately by controlling the current. The basic principle of rotating a motor’s ...
