A magnet array is used in Mover/Forcer systems to generate a controlled magnetic field that interacts with stator coils to produce precise linear or rotational motion. It is a key component in industrial automation, precision positioning, and material handling equipment.
Common materials include Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), and Ferrite. The choice depends on required magnetic strength, temperature stability, and cost. For example, NdFeB grade N42SH offers high temperature stability.
Key parameters include magnet material grade, number of poles, dimensions (length, width, height), surface magnetic field, magnetic flux density, operating temperature range, tolerance, weight, coercivity, and maximum energy product. These values must be verified with the manufacturer for the specific application.
The arrangement, such as polarity, spacing, and orientation, shapes the magnetic field to optimize force density, reduce cogging, and improve motion smoothness and efficiency. A Halbach array is one example of a specific geometric pattern that enhances field strength on one side.
