Reduced Rare Earth Magnet Motor Technology 2026/09/29

Introductions

High-performance industrial control motors and automotive permanent magnet motors are highly dependent on foreign rare earth magnets, especially heavy rare earth (such as dysprosium and terbium), which are essential for motor temperature resistance and high magnetic energy. Consequently, motor design that reduces the use of rare earth magnets has become a key technology.

Technical Advantages and Features

• Advanced Materials: Selecting high saturation magnetic flux materials (>1.8T) and high-performance silicon steel (characterized by low iron loss, self adhesion, and high strength), combined with composite magnets, to reduce motor iron loss by more than 10% and simultaneously decrease magnet costs by 5%. Using Advanced Materials to Build Lightweight, High-Efficiency Motors.
• Innovative Design to Enhance Performance: By implementing low rare-earth electromagnet and high-voltage designs, the motor speed is increased to over 20,000 revolutions per minute. Utilizing a multi-layer magnetoresistive reluctance structure enhances motor output torque by 5% and ensures the rotor's mechanical strength and rigidity.
• Heat Dissipation: Utilizing external circulation active cooling, such as liquid cooling channels inside or outside the stator, ensures that the motor operates within the appropriate temperature range, maintaining efficiency, safety, and stability. Optimizing the flow field of the working fluid reduces the energy consumption of fluid circulation and enhances the cooling effect. Optimized Cooling Design with a Water Jacket Flow Field.
