Kolektor is one of the leading producers of permanent plastomagnets based on ferrite materials and rare earths, which are an integral part of electric motors and sensors. They are primarily intended for use in the automotive industry and industrial technology. Magnets for rotors Rotors are one of three vital components of a brushless motor. With the use of permanent magnets, they ensure continuous magnetic field, which in interaction with the field of stator coils and suitable controller enable optimal continuous operation. Material choices for rotor applications include variety of sintered or polymer bonded magnets covering a range of materials such as Ferrite, Nd-Fe-B, Sm-Co or Sm-Fe-N. Depending on requirements, a variety of magnetisation patterns covering bi- or multipolar topologies is feasible. Sensor magnets In automotive and industrial applications permanent magnets in connection with sensor electronics serve as an information provider with reference to position, level, linear or rotational movement, proximity, frequency and many others. The sensoric systems convert this information to physical values of mass flow (solid, liquid, gas), speed of rotation or linear shift, torque, angle and many others. Depending on requirements a range of magnetic materials (Ferrite or Rare-Earth based) and manufacturing technologies including injection and compression moulding, sintering, over and insert moulding or glue-bonding are available. Stators Stator is one of the key components of BL motor.
