Each day you're faced with solving your customers' electric motor design problems. You balance factors such as motor performance requirements, component cost management, as well as your motor assembly process design. CyabondŽ knows the commercial and technical demands of the electric motor market and is ready to help you respond by developing custom adhesive formulations specific to your individual application. CyabondŽ 's multi-disciplined team of engineers, product specialists and chemists will provide multiple solution options detailing the adhesive, its dispensing, integration into production, curing, and post-launch evaluation.

CyabondŽ 's 15-year history of providing application-specific specialty adhesive solutions has created thousands of formulations and thousands of manufacturing successes. That's a good start, but there's more to do. 

Bonding Magnets into Stators
CyabondŽ 's sales specialists and chemists are trained to evaluate applications from your point of view. As a result, CyabondŽ has developed custom adhesive formulations for bonding magnets into stators. 

CyabondŽ 's adhesives reduce motor costs by replacing expensive, and potentially damaging, magnet clips with durable structural acrylic adhesives. And, as production yield targets continue to move higher, CyabondŽ 's custom formulated, fast-curing magnet bonding adhesives respond with epoxies that easily keep pace with the increased line speeds brought about by automation. 

Bonding Magnets onto Rotors
As end-use applications for electric motors continue to expand, so must the performance requirements of your motor designs. Commodity adhesives used in high performance applications may quickly degrade causing premature motor failure. 

CyabondŽ 's electric motor adhesives are specially formulated to resist the high temperatures and stress levels common in brushless AC and DC, and stepper motor designs. CyabondŽ 's electric motor applications team will evaluate your specific high performance application and formulate a CyabondŽ adhesive solution that will give you, and your customer, confidence in your finished electric motor products. 

Bonding Rotors onto Shafts
CyabondŽ 's ability to formulate application-specific adhesives has led to the development of bonding products for applications once reserved for mechanical joining methods such as keyways or interference fits affixing rotors onto shafts. 

CyabondŽ 's high performance anaerobic formulations provide the high viscosity necessary for these types of small gap applications with fast curing speeds to keep production levels on pace. Concerns of joint failure are eliminated with CyabondŽ 's high performance adhesives. Shear strengths of 3200 psi and an operating temperature range of -65 to 325 degrees Fahrenheit ensure long-lasting motor operation for your customers and long lasting business for you. 

Commutator and Tang Reinforcement
An extremely critical design element of any electric motor is the tang; where rotor coils are soldered onto the commutator. This connection becomes even more critical with high speed, high vibration, and high impact motor applications like weed trimmer and garbage disposal motors. 

CyabondŽ 's electric motor product development team has formulated proprietary 1:1 mixable epoxies to encapsulate the tang. These epoxies allow for the use of lower gauge wire, reducing motor weight, improving motor operating efficiency, and lowering the component costs of the motor. In addition to epoxies, CyabondŽ can formulate chemistries for custom tang designs based on your specific production requirements. CyabondŽ 's acrylic, anaerobic, cyanoacrylate, and UV curable chemistries offer extensive options for dispensing manually or automatically, bonding to dissimilar surfaces, and curing with, or without, ovens.

Materials Selection Overview
Not all electric motor components are created equal. You know that each mechanical component is evaluated on a cost-performance-benefit scale. How will each component contribute to the overall performance of the motor? How will each component contribute to the overall profitability of the motor? It's your job to balance the compromise, and contribution, of these questions. 

CyabondŽ 's line of high performance engineered adhesives will help you bring the components of your specific motor design together, maximizing the performance and profitability contribution of each component. CyabondŽ 's electric motor product development team will custom formulate the adhesives for your motor application based on careful analysis of each component; with special attention to components such as the magnets, stator and rotor. Why? Because CyabondŽ knows: It's not just science - It's solutions. 

Magnet Materials
CyabondŽ magnet bonding adhesives are available in formulations specially developed to provide high strength adhesion regardless of the magnet material or magnet condition when received. Whether you choose magnets with corrosion protection coatings, or magnets with no surface pre-treatment, CyabondŽ adhesives will secure the magnets, prevent magnet shifting, reduce motor noise, and quickly bring productivity to your design and profitability to your production. 

Stator Materials
Motor stators are now being treated on the inside with various types of corrosion resistant coatings such as zinc, powder coating, and rust inhibitors. While these coatings work to extend the stator life cycle, if not properly analyzed and managed, their presence can adversely affect adhesive bond strength and ultimately reduce overall motor performance. 

When zinc coatings are used, CyabondŽ 's engineers and chemists will analyze the thickness of the zinc and its surface adhesion properties. If the zinc coating is not properly analyzed, poor bonds will result due to inaccurate formulation of the adhesive relative to the thickness of the zinc coating. Because the final strength of the bond often depends on the adhesion of the zinc coating, CyabondŽ 's motor adhesives have been developed to interact with the zinc itself to strengthen the bond rather than resist it like many commodity adhesives. 

Powder coating, as a corrosion protection barrier, presents many of the same challenges as zinc corrosion resistance treatments. The surface thickness and adhesion of the powder-coated finish varies, and if not properly analyzed and tested the bond strength of the adhesive will be limited by the powder coat bond to the base metal. CyabondŽ 's motor adhesives development specialists will analyze your application and respond with custom formulation options specific to your performance requirements. 

When rust inhibitors are used as corrosion protection a film barrier coats the frame. This film coating is highly resistant to electric motor adhesives, and may require costly, solvent-based removal of the rust inhibitor, or time-consuming masking of the bonding area. CyabondŽ 's electric motor adhesive formulations are proven to form extremely strong bonds to surfaces with rust inhibitor treatment. Let CyabondŽ 's process engineers and chemists evaluate your component treatment options, cost-benefit factors, and line speed targets to determine the most effective component preparation and adhesive combination. 

Rotor Materials
Rotors, like many other motor components, are often covered with oils and other contaminants collected during production processes prior to bonding. Because of factors unique to rotors, such as multi-surface bonding, and varying viscosity requirements, it is critical that a controlled and clean surface be present. 

CyabondŽ 's motor adhesives product development team will assess your component's pre-bond condition, along with your motor assembly process design to identify steps to most effectively prepare the rotor surfaces for bonding. During this assessment, adhesive formulations will be developed that will ensure the strongest bond at every rotor surface including the laminations, the shaft, and the magnets. CyabondŽ 's thorough pre-production testing, cost-benefit analysis, and production automation modeling will be presented to make sure your motor design exceed it's performance requirements for your customer - and your management.
