What happens during a hard start that can affect motor longevity?

During a hard start, the motor experiences high inrush current, which is a surge of electricity that occurs when the motor is first energized. This inrush current can be several times greater than the motor's normal operating current, leading to various stresses on both the electrical and mechanical components of the motor.

The excessive inrush current can cause overheating of the motor windings, increase the risk of insulation failure, and contribute to wear and tear on mechanical components such as bearings and rotor parts. This combination of heat and mechanical stress can significantly shorten the lifespan of the motor, leading to potential failures and increased maintenance costs over time.

In contrast, options that suggest prolonged startup time, minimized electrical stress, or reduced energy consumption do not accurately represent the conditions associated with a hard start. Instead, a hard start typically results in increased stress on the motor, which is detrimental to its longevity.
