Magnetics

A magnetic component is a component performing certain function on basis of active magnetic field.

Rotors

Rotors are one of three vital components of a brushless motors. With the use of permanent magnets deliver 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 variety of magnetisation paterns covering bi or multipolar topologies are 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.

These informations are in the sensoric systems processed to physical values of 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.

 

Inductive components

Inductive components are an important element of electronic sub-systems and contain ferrite cores – mostly of proper production.

Application examples

  • Voltage transformers
  • Exterior and interior illumination of vehicles
  • Reduction and/or elimination of high-frequency interferences
  • Motor controls
  • Pressure control in pneumatics
  • RFID identification
  • Detection of metals and coins
  • Other

Stators

Stator is one of the key components of BL motor. In connection with controller, it generates a changing magnetic field in the motor and, in interaction with rotor, enables its rotation and torque transmission to the shaft. With different topologies and winding schemes, it enables motor optimization and operation adapted to a specific operating point.
