THE ELECTRIC MOTOR OF THE FUTURE
Creating Adaptive & Energy Efficient Shifting Through Magnets
THE PROBLEM
Electric motors impact almost every aspect of today's world in home appliances, computers, and the increasing array of electric vehicle models. While considerably more efficient than combustion engines, electric motors are the single biggest consumer of electricity, responsible for approximately 45 percent of global electric power consumption. As electrification continues to expand, there is a pressing need to improve efficiency, create more durable equipment, and find adaptive ways to enhance performance in changing road and weather conditions.
OUR SOLUTION
Researchers at The University of Alabama have developed a permanent magnet synchronous motor that can generate power at lower temperatures and quickly adjust to a changing environment, providing appropriate speed and torque as needed depending on driving habits and terrain. This novel design uses a radial-axial hybrid stator, increasing nimbleness and efficiency while reducing the wear-and-tear on materials, significantly impacting maintenance costs for the automotive, aerospace, and appliance industries.
THE ADVANTAGES
- Longer operating time at high speed than a winding-changing motor (WCM) due to reduced current & temperature
- Smoother transitions & easier to maintain than a magnet pole-changing motor (MPCM)
- Higher torque density than a mechanical-assisted motor (MAM)
- Ultimately more efficient & robust than other solutions
