The use of motor structures which can concentrate magnetic flux allows ferrite PM motors to achieve performance and power densities that approach those of PM motors using rare earth magnets, but without the cost penalties and supply source concerns of rare earth magnets.
University lab's motor eliminates pricey rare-earth magnets.
Novatorque energy efficient motors, Portescap smaller-size brushless DC motors, Pittman customized motors, Kollmorgen stainless steel motors, Crouzet expanded motor series, and a report from IHS on rare earth mineral supply.
Lower-cost motor technologies exist that can be an attractive alternative to neo-based BL PM motors - and are not subject to unpredictable supply chains
Implementing a predictive maintenance (PM) program can be tough. Despite its proven success, many companies have been operating the same way for over 50 years and donâÂ€™t know where to start. Understanding where to start and where to focus is critical. The intention of this article is to give insight to start and sustain an effective program using todayâÂ€™s technology and devices.
America suffers $4.4 billion in losses due to earthquakes every year. While that's a drop in the bucket for our $16 trillion plus GDP, it's still a substantial amount of money, and some people are working to lessen those losses. One group is Earthquake Protection Systems (EPS), a company that is designing bearings to better protect buildings from earthquake damage.
