Thus far the product implementations I have experienced have really missed the mark. I see a HVAC unit with a fan motor that saves energy but they replace a $39 motor with a $700 motor to get the savings. As the consumer that both buys the system and operates it the actual payback is negative. They have to get the total life cycle cost to improve before I can even be interested. It is also real life that the reliability gains touted due to thermal improvement are far overcome by the reliability degredation by adding a bunch of electronics.
We all should save energy, but how much will you save? How often do you use washing machine? Me? 2 to 3 washes a week and the heater is the most energy consuming part of it. I'd rather get a washing machine that is going to last for 10 years than the super efficient one. You can't cheat on heating :)
This sounds like it uses similar technology as a VFD (drive) except that the frequency is maintained at the original 60Hz. Many high efficiency appliances now use brushless DC motors that require drives that incorportate similar feedback circuitry. Is this intended to be a lower cost alternative? Also, is the controller 3rd party certified? There are concerns about the single fault failure mode of the semiconductor circuitry and software (firmware). IEC/UL/CSA 60730 documents include requirements to address safety concerns.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
