Magnet-rotors are used to generate the ignition spark in 2 wheelers when the rider kick-starts the motorcycle. These rotor assemblies vary according to the 2 wheeler model and engine displacement.
Each magneto rotor assembly consists of a cup inside where a boss is inserted and riveted in place. This assembly is broached and reamed post which needs to be ultrasonically cleaned. Once the contaminants are removed, four magnets are inserted and retained in place with a curable adhesive film. The curing takes place in an oven with controlled temperature line which is highly flexible, robust and considerably reduces the manpower requirement while improving productivity.
