AI Technical Summary
⚠Technical Problem
Electrical appliances with electric motors face damage from impacts due to rotating components deviating from their rest position during high-speed rotation, leading to frictional wear and debris contamination, which reduces the motor's lifespan and performance.
⚗Method used
A method and system for detecting free fall using sensors and controlling the electric motor to brake or decelerate upon impact, utilizing an inverter to manage current flow and reduce component contact by controlling the motor's speed at the time of impact.
🎯Benefits of technology
Reduces the likelihood of component damage and debris generation by maintaining a safe distance between motor parts during impacts, thereby extending the motor's lifespan and maintaining performance.
