I recently came across a cool innovation in servo technology from a little company called QuickSilver Controls. The Mosolver is a servo motion actuator that infuses a position feedback sensor into the structure of a high-pole-count AC motor. This combination eliminates the need for an encoder and resolvers, and it results in robust closed-loop motion control.
For further precision, the servo's designers have added sense coils within the motor. Voltages are induced by these sense coils from a combination of the pulse-width modulation current ripple and the flux steering as a result of the rotor and stator interaction. The design removes a separate feedback device to make the overall package smaller (along with the overall bill of materials). And having everything packaged together increases the system's reliability. Many more details are available in the data sheet.
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Clean diesel continues to be the fuel of choice for transportation authorities in major U S cities, in spite of competitive options aimed at reducing emissions, according to a nonprofit agency that represents diesel engine and equipment manufacturers.
A panel at this year's Consumer Electronics Show in Las Vegas discussing upcoming FAA regulations for non-military drones brought out many of the issues that concern both industry and federal regulators.
