The biggest difference between brushed and brushless motors, unsurprisingly, is the brush. But what does that really mean? The principle behind the internal workings of brushed and brushless motors are otherwise much the same. When motor windings become energized, a temporary magnetic field is created to repel or attract permanent magnets. This magnetic force is converted to shaft rotation, allowing the motor to do work. As the shaft rotates, the electric current is routed to different sets of windings, maintaining electromotive repulsion or attraction, forcing the rotor to continually rotate. The History of Brushed and Brushless Motors Brushed DC motors...

If NASA’s Mars rover can make groundbreaking scientific discoveries (like the fact that Mars had conditions to support life) on wheels alone, think of what we can accomplish by taking to the skies. NASA is in the planning process of its 2020 Mars rover mission, following the massive success of the Curiosity rover. When the next rover heads to Mars a few years from now, it’s likely that it will be accompanied by a drone to help expand our understanding of the planet’s landscape. NASA and Drones Drones have been exceptionally useful for investigating areas of our planet that are...

FPV and Drones Flying your drone with first person view (FPV) goggles is the closest you can get to being a bird. FPV incorporates the use of goggles to visually experience what the camera on your drone sees from the safety of the ground, as though you could hop in and fly the UAV yourself - but without a shrink ray or a pilot’s license. Most camera drones utilize onboard sensors to continuously stabilize flight and keep the UAV well-balanced to prevent the drone from flipping or rolling too aggressively. Today’s drones are fast, agile, and exceptionally powerful. Flying with...
