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 to properly position the rotor if no mechanical locating features are on the shaft.
• Various adhesives can be used to bond the target rotor to the motor shaft. Shaft alloys, operating environment, and shaft speed and
acceleration should be taken into consideration when selecting an appropriate bonding agent. Loctite threadlockers and retaining
compounds have proved effective in bonding the target rotor to the motor shaft. Loctite 263 and 2760 threadlockers and Loctite 638 and
680 retaining compounds are good candidates. These materials have been effective in past experience; testing under actual operating
conditions should be used to qualify any bonding material.
• For best results, the motor shaft should be clean and free of any oils, lubricants, or solvents.
• Apply adhesive around the leading edge of the shaft and inside the hole in the rotor. Use a rotating motion when assembling the magnet
to the shaft to insure good adhesive coverage.
• The use of primers and activators can be used to improve bond strength and cure rate.
• For non-critical applications or for fast bonding for evaluation, a cyanoacrylate adhesive (super glue) can be used. Loctite 401 and 410
have proven effective for quick bonding applications.
