The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

New research describes advanced motor control devices. These control devices are units designed to correct errors and improve the performance of the motors. This researcher has opted for cutting-edge ...

A FULL discussion is given in this book of the practical theory of the induction motor and of several of the main types of alternating current motors. The author also gives a historical account of the ...

Efficiency standards were once confined to integral horsepower motors but may soon apply to small motors and make certain kinds impractical to manufacture. Today, the electric motors that are of most ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Sometimes you may need to correct power factor (PF) at a single motor. This means sizing PF capacitors for that motor. The good news: If you size these capacitors correctly, you'll lower your ...

Permanent magnet synchronous motors are up to 15 per cent more efficient than induction motors and are the most power-dense type of traction motor commercially available. New Delhi: Growing demand of ...
