DC brushless starting magneto integrates the brushless DC starting motor and magneto and applies the electronic commutation technology to the motorcycle's starting motor, so the reducing mechanism and overrunning clutch are omitted, thus effectively simplifying the engine structure and improving the operational reliability, it will be the mainstream of future development. The brushless DC starting magneto consists of internal stator and flywheel external permanent magnet rotor, the flywheel external permanent magnet rotor is fixed with the engine crankshaft, 6 Nd-Fe-B magnetic tiles with N-S poles working at higher temperature are evenly pasted to the inner cavity of flywheel.
