Why does the electric fan always rotate clockwise?
The fan blade of a conventional fan has a tilt angle (the steering is designed from the angle of the tilt angle). The motor causes the fan to rotate and the space-time is compressed, causing air flow (resulting in wind). The direction of flow is related to the direction of the fan's rotation and the inclination of the fan blade.
It may be related to power. The steering of the motor is subject to alternating current, and the alternating current is standard, so that should be the reason.
Generally clockwise direction is the direction of the screw lock, fan leaves must be safe, and the screws must be tightened in the same direction. This should belong to the standardization of parts
