The fan filter unit control system of BLDC motor for extreme cleanness and method thereof and the management system manageability a fan filter unit control system using network

摘要

PURPOSE: A fan filter unit control system for driving a BLDC motor, a method for controlling the same, and a management system for managing the same are provided to improve a power factor by modifying a structure of a linear power supply. CONSTITUTION: A fan filter unit control system for driving a BLDC motor includes a voltage supply portion(101), a BLDC driver portion(102), a BLDC motor portion(103), and a control portion(104). The voltage supply portion(101) rectifies AC power to DC power and outputs a driving voltage of the BLDC driver portion(102), a driving voltage of the BLDC motor portion(103), and a driving voltage of the control portion(104). The BLDC driver portion(102) outputs constantly the driving voltage of the BLDC motor portion(103) according to the driving voltage of the BLDC driver portion(102). The BLDC motor portion(103) drives a three-phase BLDC motor and outputs an alarm signal according to a driving state of the three-phase BLDC motor. The control portion(104) controls the driving voltage of the three-phase BLDC motor.
