Magnetic Rings Assembly Instructions
Target Rotor Mounting Guidelines, Engineered Polymer Hub (Mounting Style H) For Press Fit Application
• Proper alignment of the target rotor is critical for optimal performance.
• A machined step on the motor shaft provides a quick and repeatable method for positioning the target rotor. Spacers or other fixturing should be used if no mechanical locating features are on the shaft.
• A chamfered lead in on the shaft will aid in aligning the rotor.
• Prior to insertion, the motor shaft should be clean and free of any oils, lubricants, or solvents.
• Proper fixtures and support must be used to ensure the magnet is pressed on straight and aligned with the motor shaft.
• Opposite end of motor shaft should be supported to avoid undue stress on motor bearings during the pressing operation.
• In applications with high torque or environmental extremes, a retaining compound can be used to enhance the strength of the press fit.

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 which 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.
