If a belt on a blower is too tight, what will happen to the blower motor current?

When a belt on a blower is too tight, the blower motor faces increased resistance when trying to rotate. This additional strain on the motor leads to a higher electrical current draw to overcome the mechanical load. As a result, the motor must work harder to maintain its operational speed and performance, thus causing an increase in motor current.

If the belt were too loose, it would slip, resulting in reduced efficiency and potentially lower current. A tight belt, however, does not allow for any slippage; instead, it compels the motor to exert more energy, leading to a noticeable increase in current. Understanding this principle is critical for troubleshooting motor performance and ensuring the longevity of both the motor and the blower system.
