As the coil flips over, the magnetic field through the coil changes—that's exactly what you need. But there you go, an electric motor and an electric generator are the same thing. It just ...

So, there is a reason to consider these curly fields. If the coil of wire in the motor is spinning, then there is a curly electric field in there. What does this curly electric field do?

For anyone involved in the construction of small electric vehicles it has become a matter of great interest that a cheap high-power electric motor can ... top of the stator coils and found them ...

This means that the motor effect forces continue to cause anti-clockwise rotation of the coil. Electric motors affect almost every aspect of daily life. They can be found in homes, schools and ...

The first was the cheap, highly efficient MCT (Magnet-free Contactless Transmitter) motor, which replaced the typical permanent rare earth magnets in the rotor with a series of wound-coil ...

Using the regenerative braking system in an electric or hybrid vehicle doesn't wear out the brake pads at all and adds up to ...

[Slider2732] built a small electric motor that ... Using coils with many turns of very fine wire helps to draw less current while keeping an appropriate magnetic field for the motor to run.

Current running through that coil can make the axle of a motor ... that can both multiply the strength of the electric field ...

A Texas-based startup has raised US$4.5 million in seed funding to develop and commercialize a remarkable electric ... field weakening in a unique way. Field weakening is used to increase motor ...

it moves parallel to the magnetic field, producing no force. This would tend to make the motor come to a stop, but two features allow the coil to continue rotating: ...

In the second article, we discussed the underlying principles of electric motors. Today we shall discuss one of the most important characteristics of the motors, field weakening. Field weakening ...
