The Background of Rare Earth Export Control Policy
Against the backdrop of escalating trade tensions between China and the United States, China announced in April 2024 that it would suspend the export of six heavy rare earth metals and rare earth magnets, requiring special permits for these products to be shipped abroad. This move is seen as a response to the Trump administration’s increase in tariffs on April 2.
Rare Earth Export Control Solutions
Information from Chinese Authorities: Primary processed products made from samarium-cobalt permanent magnetic materials, neodymium-iron-boron permanent magnetic materials containing terbium, and neodymium-iron-boron permanent magnetic materials containing dysprosium, such as magnetic discs, magnets, magnetic rings, and related magnetic components, are subject to control.
However, electronic components (such as motors) or electronic products (like speakers and headphones) that are further processed do not fall under the control scope.
Material Solution: Providing Neodymium Magnets without Controlled Rare Earth Elements
To actively respond to the national policy on the export control of rare earths, we can ensure that certain types of neodymium magnets do not contain the controlled rare earth elements through optimized formula design.
Product Solution: Providing Motors
Types of Permanent Magnetic Motors Produced by Tengye
| Surface-Mounted Permanent Motors: The permanent magnets on surface-mounted poles directly face the air gap, providing benefits for processing and installation. However, due to armature reactions, these magnets are directly subjected to demagnetizing effects.
| Outer Rotor Motors: Under the same volume or mass, outer rotor motors exhibit higher output torque. Additionally, the longitudinal dimensions of outer rotors are relatively small, allowing for broader spatial suitability and less installation space constraint. Generally, inner rotor permanent magnetic motors have better heat dissipation and sealing performance than outer rotor permanent magnetic motors.
| Deeply Embedded Permanent Motors: Permanent magnets with built-in poles are placed inside the core, leading to complex processing and installation while suffering from significant magnetic leakage. However, this design allows for the placement of more permanent magnets, enhancing magnetic flux density in the air gap and reducing the motor’s weight and volume.
