Most DC fan motors won't function with out it first sensing the burden of the blades. Others require a calibration process that takes as much as 7 minutes, during which time the motor sets up based mostly on the size and weight of the blades put in. This is very true with large ceiling fans that use the identical motor with various blade span options. Attempting to function the fan earlier than the blades are put in might injury the motor completely. Therefore, please comply with all instructions carefully which can be included with the fan!
