Kristin, do you have numbers for the cost of an SR motor compared to a conventional induction motor?

Rare Earth Shortages

Kristin, Excellent article.  I know some suppliers are moving to SR technology as a way to improve the performance of induction motor systems.  A key advantage is that SR motors can be paired up with variable speed drives to the eliminate slip losses associated with induction motors while also boosting efficiency and create more compact sizes. Other benefits of the technology are related to higher reliability. The rotor construction itself is robust, plus there is no squirrel cage on the rotor side.  Great series on rare earth shortages.

If we are going to be creating a network that serves us, one of its most critical nodes will need to be ourselves. This is where wearable technology comes into play.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
