Brushless motor controller and a brush electric difference analysis

Brushless motor controller and a motor controller belongs to a kind of motor controller, but there is an difference, said below small make up the difference in energy saving and maintenance aspects. Energy-saving: compared with motor controller, the brushless motor controller adopts frequency conversion technology in electric power control is energy-saving, typically with frequency conversion air conditioning and refrigerator. Maintenance aspects: changing the carbon brush, brush motor controller need to be replaced in a timely manner, timely for change will lead to damage to the motor controller. The brushless motor controller is do not need to change, and much longer service life than brush motor controller, less maintenance, but if broken it need to replace the motor controller. Through the above said, you have brush for brushless motor controller and motor controller to understand what happened.
