Motors for electric power steering: These motors assist steering operations. Because power steering until now has been hydraulic, it drained power from the engine even when no steering operation was underway. By converting the power steering to electric, energy consumption when the power steering is not in operation is reduced, which improves the fuel economy. Also, eliminating the hydraulic pipes improves the car's space efficiency. The use of rare earth magnets in these compact, high output motors is expanding.

Drive motors and generators for hybrid, fuel cell, and electric cars: Hybrid cars use an electric motor to assist the engine during start-off and acceleration. Fuel cell cars and electric cars are driven by the electric motor alone. Cars that are equipped with a generator, use that generator to recharge the battery as required, even while the car is traveling. During braking, either the electric motor or the generator creates braking force through electric generation load and that energy is stored back into the battery.  That energy is used when the car starts up again, which improves the fuel economy. These motors require compact size, high output, and the ability to stand up to heat, so they use rare earth magnets.

Sensors: The requirements for automotive safety and comfort are becoming more and more demanding. Meeting these demands requires sensors to detect rotation, angle, and position. Sensors using rare earth magnets are compact and accurate and are helping raise the reliability of cars even as those cars become more complex.

Linear Servo Motor: Simply stated, a linear motor is the same as a rotary motor that has been "unwrapped." They operate exactly the same as rotary motors, where the same electromagnetic equations that describe how a rotary motor produces torque now describe how a linear motor produces a direct force. In many applications, linear motors offer distinct advantages over conventional rotary drive systems. When using a linear motor, there is no need to couple the motor to the load by means of intermediate mechanical components such as gears, ballscrews, or belt drives. The load is directly connected to the motor. Therefore, there is no backlash or elasticity from the moving elements. Thus, the dynamic behavior of the servo control is improved and higher levels of accuracy are achieved. The absence of a mechanical transmission component results in a drive system with low inertia and noise. In addition, mechanical wear only occurs in the guidance system. As a result, linear motors have better reliability and lower frictional losses than traditional rotary drive systems.

Semiconductor

More and more cost pressures are driving the semiconductor industry to source lower costs with high reliability found in China. Tridus is a leader in providing magnet and value-added assemblies to PVD sputtering, photolithography, and motion control applications. We have a Class 10000 clean-room for assembly in our Tianjin plant in China.

Oil and Gas

For the harsh oil and gas environment, our plants have developed a high quality and reliable Samarium Cobalt grade that supports down-hole and subsea applications such as: NMR exploration tools, Permananet Magnet generators, Magnetically actuated valves, and magnetic coupling devices. We have also developed a neodymium grade 55 to support the pipeline cleaning mfl tools predominantly looking for the highest yet reliable B field. Our experience include special processes that support the high pressure and temperature environment such as potting, encapsulation, welding and the use of high grade materials.
