Why your fan rotate slowly?

A fan may rotate slowly due to several reasons, such as a faulty motor, insufficient voltage supply, or a buildup of dust and debris that hinders movement. Additionally, if the fan's bearings are worn out or if there is a malfunction in the speed control settings, it can also result in slower rotation. Checking the power source and cleaning the fan can often resolve the issue. If problems persist, further inspection or professional repair may be necessary.
