Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

Market players are focusing on creating and developing energy efficient motors that utilize permanent magnet materials along with high magnetic flux density due to increasing environmental issues.

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

The energy-efficiency regulatory update scheduled for 2023 will affect builders of HVAC equipment, industrial fans, cooling towers and pumps, including those used in irrigation systems. The new ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...
