Experts from the Eidgenossische Technische Hochschule (the Swiss Federal Institute of Technology) in Zurich, a scientific and technological university in Switzerland, have recently managed to create a small motor the size of a matchbook that is the absolute uncontested holder of the spinning record. The tiny device i... |

Brushless DC electric motors are a design variation derived from the old brushed electric motors except that the relative motion of the rotor and the stator is reversed. To understand how this is done, one must first understand the basic construction and operation of a brushed DC electric motor. Typical DC motors imp... |

The design of the electric motor, which converts electrical energy into mechanical energy, hasn't changed much since it was invented, some 50 years ago. New technological developments in the field of superconductors are about to change that.El Hadj Ailam and colleagues working at the Universit Henri Poincar in Na... |

Would you feel confident to race against a Viper or a Corvette when you're in a 20-year-old pickup-truck? Probably not. But would you feel safer driving a 4.3 tons Hummer H1 truck on a busy highway? You surely would, don't even try denying it. I guess that's why the number of SUVs sold in the US is co... |

The Wankel rotary engine is another type of internal combustion engine that features a very clever rearrangement of the four elements of the Otto cycle. It was invented by the German engineer Felix Wankel in the 1950s.In the piston engine, the cylinder performs all four steps: intake, compression, combustion and ex... |
