Fan system

Abstract

A fan system includes a stator assembly and a monitoring and sensing module. The stator assembly is electrically connected to the monitoring and sensing module, and the latter includes at least one sensor unit, at least one monitoring unit and a signal processing unit. The sensor unit of the monitoring and sensing module senses an operating state of the fan system, and the signal processing unit processes the sensing results of the sensor unit and actively generates a warning in the event of an abnormal operating state of the fan system, so as to protect the fan system against an operation failure due to any abnormal operating state and thereby reduce the fan system's maintenance cost.
