Every time you use a hand tool, domestic appliance or a car’s power windows, air conditioning or wipers, chances are you are using a permanent magnet type motor. Which also means you are probably benefiting from induction heating applications developed by EFD Induction engineers.
”Over the past few years, more and more motor manufacturers have turned to EFD Induction to help them improve productivity and quality. One area where induction has had a major positive impact is the replacement of conventional assembly methods (mechanical clips) by induction bonding. With induction bonding, single-component epoxy adhesives are cured by heating the motor housings. Magnet properties remain unaffected during the process. The benefits of induction bonding are varied and significant. To start with, the vibration noise experienced with mechanical assembly is virtually eliminated. Also, epoxy single-component adhesive does not require extra preparation work. Finally, the precise repeatability of induction bonding ensures uniform quality. EFD Induction designs, builds and customizes automated equipment for magnet bonding. Our resources include complete testing facilities to assess magnet position and over-all strength. These testing facilities are valid for production lines with a capacity of up to 600 motors per hour. Of course, magnet bonding is far from being the sole application developed by EFD Induction for motor manufacturers. Our engineers also design equipment for hardening rotor shafts, for curing stator isolating varnish, for burning wire ends varnish—all for full in-line production. So next time you drive a car, use an electric drill, or switch on a hair dryer, spare a thought for EFD Induction’s hard-working engineers—and for the hard-working induction technology they have perfected.
