4. Principis de funcionament
The starter motor is an electric motor that rotates the engine's flywheel to initiate the combustion process. When the ignition key is turned to the "start" position, electrical current flows from the battery to the starter solenoid. The solenoid then engages the starter's drive gear with the engine's flywheel and simultaneously sends power to the starter motor. The motor spins, cranking the engine until it starts. Once the engine begins to run, the starter's drive gear disengages from the flywheel to prevent damage from over-speeding.
This specific starter is engineered for reliable performance, having been tested for quality to ensure proper function and durability under typical operating conditions for Yamaha Scooter XP500 TMAX models.
