EMI Suppression of Permanent-Magnet DC Motor
Abstract:
Permanent-Magnet DC Motor was widely used in small domestic electrical appliances and electronic toys. The Motor generates EMI when working, which is harmful to the electronic equipment nearby and human. This article describes the structure and principle of the Motor and the reason of generating EMI. It also puts up several solutions through the analysis and testing of EMI caused by the motor （including Terminal disturbance voltages, Disturbance power and radiated disturbance） and concludes with a best solution via analyzing their advantages and validity.[著者文摘]
Key words:
permanent-Magnet DC Motor; EMI; terminal disturbance voltages; disturbance power; radiated disturbance; suppression; small domestic electrical appliances ; electronic toys
