NovaTorque, Inc. has introduced 900 RPM versions of its 1.5, 2, 3 and 5 hp models. The new models provide a full load motor-only efficiency rating of 92% to 94% compared to approximately 82% to 87% ...

Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

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 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 ...

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.

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.

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...

British company Equipmake announced a new AMPERE project to develop the world’s most power-dense permanent magnet electric motor within 12-months. The peak power density, available for a short time, ...

Towards the end of July I read a post about how efficient AC induction motors are and that how using them and reducing their speed will help us all to reduce the green-house effect, save money and the ...

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 ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...
