What is it about?
The research presents a new electric motor design named PHEPS. The primary objective is to enhance torque, efficiency, and power density. This is accomplished through a distinct structural advance: incorporating an air gap to diminish magnetic losses. It employs two separate stators to prevent spatial interference, a departure from traditional designs. The design undergoes testing and is benchmarked against a conventional model using ANSYS Maxwell simulation software. Outcomes reveal that the PHEPS model performs markedly better, demonstrating greater efficiency, increased torque, and reduced torque fluctuations.

Why is it important?
This study is crucial as it presents a new motor design, known as PHEPS, that tackles major drawbacks seen in conventional electric motors, like magnetic energy loss, space limitations, and less-than-ideal torque performance. By featuring an extra air gap and divided stators, this design offers improved control over magnetic flux and makes better use of available space, allowing for more coils and permanent magnets to be included. These advancements result in marked enhancements in torque, power density, and efficiency, factors that are vital for areas such as electric cars, green energy systems, and industrial machinery. The simulation outcomes convincingly demonstrate the PHEPS motor’s outstanding capabilities, signifying its potential impact in real-world applications.
Perspectives
This research work presents the PHEPS motor, a groundbreaking electric motor design created to overcome major drawbacks of traditional motors, such as energy losses due to magnetism, limited space, and insufficient torque performance. By incorporating an extra air gap and a divided stator layout, the design greatly enhances the control of magnetic flux and makes it possible to integrate more coils and permanent magnets. These improvements lead to significant boosts in torque, power density, and efficiency. Confirmed through comprehensive simulations with ANSYS Maxwell, the PHEPS motor showcases outstanding performance, positioning itself as a promising option for upcoming electrical vehicle models, renewable energy projects, and industrial drive applications.
