You see examples of BLDC motor controllers almost everywhere, but you may not know it. BLDC motor controllers use IGBTs (integrated-gate bipolar transistors) or FETs (field-effect transistors) to provide power to the motor’s coils. Many also use electronic commutation to drive coils, which switch the current between different phases.
AC gear motors are electric motors that use an alternating current. They generally have two parts: the outside stationary stator and the inside rotor. Slip rings or a permanent magnet generate the magnetic field on the rotor.
Whether you’re using a traditional model or a gearmotor with encoder, using it the right way will help extend its life and give you better results.
The brushless DC motor is quickly gaining popularity across several industries. BLDC motor design houses don’t use brushes for commutation; they use electricity instead.
Fighting Online Harassment with New Tools Powered by AI The company’s Jigsaw division is on a mission to protect the Internet’s most vulnerable. Trouble is, doing good is a lot harder than “Don’t be evil.” The post Inside Google’s Internet Justice League and Its AI-Powered War on Trolls. Called Conversation AI, Jigsaw’s new software is aimed at blocking …
A new world record for quantum teleportation has been set, bringing quantum communication networks that can stretch between cities a step closer. Two independent teams have transferred quantum information over several kilometres of fibre optic networks. Being able to establish teleportation over long distances is a crucial step towards exchanging quantum cryptographic keys needed for …
Researchers at the Swedish Institute of Space Physics have used measurements from NASA’s MMS Magnetospheric MultiScalesatellites to reveal that there are ripples, or surface waves, moving along the surface of shocks in space. Such ripples in shocks can affect how plasma is heated and are potential sites of particle acceleration. These results have been published in the …
The Largest Stars in the Universes The largest known stars in the Universe. VY Canis Majoris (VY CMa) is a red hypergiant star located in the constellation Canis Major. With a size of 2600 solar radii, it is the largest known star and also one of the most luminous known. But there might just bigger …
The existence of plumes would make studying the moon’s interior ocean easier. In the seminal science fiction series Space Odyssey, novelist Arthur C. Clarke called attention to the Jovian moon Europa’s special place in the Solar System. At the end of the series’ second novel, 2010: Odyssey Two, a spaceship sent to the Jupiter system …
Share It…. if you can ……. If you traveled from Earth to the moon with 99.9% the speed of light, your trip would take only 1.27 seconds (Earth’s time scale). With the same speed, you would reach Mars in just 4.36 minutes (Earth’s time scale). To reach the edge of the observable universe with the …
