Magnetic tile is the most important component in the motor. It is mainly used in permanent magnet motor, communication motor, DC motor, linear motor, brushless motor, motor, motor and other motor categories. To drive and we usually use repulsion motor magnets and magnet motor attractive tile type motor magnets usually waste magnetic tile will be selected to form radial magnetizing ring usually small DC motor magnetic tile (Arc Magnet) three kinds of magnetizing method:
1, magnetic tile alone magnetizing, and then loaded into the casing, and then install all;
2, magnetic tile into the casing (sticky), re magnetizing, and then install all;
3, magnetic tile into the casing (sticky), and then an electric car, motor, magnetic tile installed products, and eventually all magnetized.
The influence of different methods on magnetizing of magnetic tile:
Magnetizing method,
1. the first to open the magnetizing magnetizing method, because when magnetizing without external magnetic circuit, did not form a closed loop magnetic tile magnetization is not easy to charge full, influence of the magnetic flux density of magnetic tile, is usually closed will lower magnetization;
2. the second magnetizing method is the most commonly used, due to the closed magnetization, the magnetized magnetic flux density is the highest, and can through the charging head shape to adjust the air gap flux density waveform, satisfied different motor function request, but in the motor installation, operation needs special tooling installation, otherwise may be because of magnetic attraction factors of the injured or the rotor magnetic tile magnetic particle;
3. third kinds of magnetizing method to closed magnetization (because the rotor plate is a good magnetic data), magnetic flux density after magnetizing the tile size is usually between the first and second note: in the use of the magnetization, the best carbon brush and the rotor winding is in open condition, or touch the surface of the carbon brush and the commutator may occur fire scene.
The magnetization method two, the first magnetizing method is lower than second, third magnetizing methods, the surface remanence is 10% or so, and generally speaking, it is more reasonable to choose second magnetizing methods;
Magnetizing method three,
1., the first method of magnetization is very convenient, some factories choose solenoid type magnetizing, the production power is very high;
2. second magnetizing methods, some factories to use the blunt, some selected in punch, magnetic tile or ring needs to glue drying, production is also very convenient; 3. third magnetizing methods, there are many small motor (mostly three slots) using this method, the rotor because no magnetic force is good installation, but is not convenient to view the magnetic charge well.
