What happens when a motor's operating temperature exceeds its design limit, such as $155^{\circ}\text{C}$ for common insulation?

Answer

The insulation's lifespan decreases exponentially

Exceeding the design temperature limit for motor insulation causes the lifespan of that insulation to decrease exponentially, leading to eventual failure.
