SYSTEM AND METHODS FOR REDUCING NOISE IN AN AIR MOVING SYSTEM

摘要

A centrifugal blower system includes a centrifugal blower assembly for generating airflow. The centrifugal blower assembly includes a housing, a motor coupled to the housing, and at least one impeller coupled to the motor. A motor controller is coupled to the motor. The motor controller is configured to receive at least one feedback parameter and to transmit instructions to the motor to control an operation of the motor based on the at least one feedback parameter. The operation of the motor is configured to reduce noise in the centrifugal blower system.
