Firstly, the approximate layout principle of the turbocharger; the exhaust turbocharger is mainly composed of the pump wheel and the turbine; of course, there are other control components. The pump wheel and the turbine are connected by a shaft; that is, the rotor; the engine is discharged. The exhaust gas drives the pump wheel; the pump wheel rotates the turbine; the turbine is pressurized to pressurize the intake system. The supercharger device is on the exhaust side of the initiator; therefore, the operating temperature of the supercharger is high; and the supercharger The rotor speed is very high during operation; it can reach hundreds of thousands of revolutions per minute; such high speed and temperature make the common mechanical needle roller or ball bearing unable to work for the rotor; therefore, the turbocharger uses a full floating bearing; Smoothed by the oil; and the coolant is cooled by the supercharger.
So align this layout principle; pay attention to some issues when using this kind of initiator:
1. After the engine is started, it should work at an idle speed for a moment; make the smooth oil reach the certain working temperature and pressure; prevent the friction from accumulating due to the oil-free bearing when the load is added; or even jam. When the vehicle is parked, the booster rotor has a certain inertia; therefore, the initiator should not be extinguished immediately; it should be idle for a period of time; so that the temperature and speed of the supercharger rotor are gradually reduced. Immediately extinguishing the flame will cause the oil to lose pressure; Inertial transformation is not smooth and damaged.3. Always check the oil quantity of the engine; prevent the bearing from failing due to the shortage of oil and the locking parts are stuck. Timing replacement of oil and machine filter; due to the high demand for smooth oil for full-floating bearings; should use the manufacturer's regular trademark oil.5. The air filter is removed periodically; the air filter is dirty and the intake resistance is added; the power of the initiator is reduced. Often check the airtightness of the air intake system; air leaks will draw dust into the booster and the initiator; damage the booster and the initiator.7. Because turbocharger rotor bearings are highly precise; the operating environment requirements for repairs and installations are severe; so if the supercharger is faulty or damaged, it should be repaired at the designated repair station.

There are two main Bonded NdFeB Magnet manufacturing methods:
ï‚·Bonded Injection Plastic Moulding NdFeB
ï‚·Bonded Compression Moulding Ndfeb
Bonded Compression Moulding NeFeB Magnets ( called Compression Bonded Magnets) are made by using many isotropic Neodymium, Iron, Boron materials, as well as crushed and powdered Samarium and Cobalt ingredients.Combinations of different elemetal grades are used to creat specific magnetic properties. Compression Bonded Magnets offer higher magnetic strength than Injection Plastic moulded magnets. Although Compression Bonded Magnets have higher magnetic particle density, ther are limeted to simple geometric shapes due to the compaction process. The epoxy is used to protect the magnet surface from industrial solvent and automotive fluids. The normal applications of the magnets range from -40℃ to 150℃.
The advantages of Compression Bonded Magnets:
1. High quantity and even volume manufaturing, with up to millions of pieces per year
2. Single-time moulding and multi-poles orientation.
3. Effective surface treatment to prevent corrosion. The product is coated with epoxy resin to be protect the surface smoothing.
4. Excellent magnetic properties. The energy of Compression Bonded Magnets is 3 times as high as anisotropic ferrite magnets.
Application of Compression Bonded magnets:
•Mini motors
•Automatic contolling devices
•Sensors
•Drivers
•Telecom
