What happens when a motor operates above its rated supply voltage?

When a motor operates above its rated supply voltage, it is subjected to excessive electrical stress that can lead to overheating and damage. Motors are designed to function optimally at their specified voltage, and exceeding this level can increase the current drawn by the motor, resulting in higher heat generation within its windings. This increased temperature may lead to insulation breakdown, reduced life expectancy of the motor, and potential failure of internal components. Therefore, operating a motor beyond its specified voltage is risky as it jeopardizes its reliability and longevity.
