Multipole Magnetic Rings
Phoenix America LLC's multi-pole magnetized target wheels are uniquely constructed of a proprietary mix of magnet materials and engineering thermoplastics. The result is a unitized magnet target wheel that produces a very accurate, homogeneous magnetic field and has very tight mechanical tolerances. This provides for a very low-cost product, compared to the traditional, high component count wheels with individual magnet bars glued into place.
Tight tolerance control, precise pole location, and very consistent magnetic performance make these target wheels well suited for speed, commutation, encoding, counting, and tachometry applications. Three standard grades of materials allow for a wide range of air gap capabilities. Adhesive bonding is the recommended mode of mounting, although many customers have satisfactorily attached these targets to their shafts using various other schemes. Please feel free to contact Phoenix America LLC for application engineering or product assistance.
