A newly patented invention avoids the cumbersome procedure of "fine tuning" electric motors. At NASA's Marshall Space Flight Center, Ann M. Casper designed a brushless dc motor that dynamically times the commutation between the rotor and stator--without disassembling its housing. She put Hall-effect sensors on the commutation board to provide feedback on the rotor position. A tool inserted into the endcap, while the motor runs, "tunes" the motor for maximum operating efficiency. invention received United States Patent 5654599.
Both traditional automation companies and startups are developing technologies to improve processes on the factory floor, while smart sensors and other IoT-related technologies are improving how products are handled during transport and across the supply chain.
