Different ferrite inhibit element, the best inhibiting frequency range. Generally the higher the permeability, inhibit the frequency of the lower. In addition, the greater the volume of ferrite, inhibit fan motor the better the results. In a certain volume, long and thin shape than single phase motor price stubby little inhibition effect is good, the smaller the diameter water pump price inhibition effect is better. But with the help of dc or ac drift, and problems of ferrite saturation, inhibiting component cross section, the greater the more difficult saturated, www.facebook.com/dongfeng.motor affordable, the greater the flow deviation. generator EMI absorption magnetic ring/magnetic beads differential mode interference suppression, through its current value is proportional to its volume, both disorders caused by saturation, reduces the component performance; , the suppression of common- mode interference to the power of the two wires (plus or minus) through a circular and at the same time, the effective signals Water pump in differential mode,

EMI absorption has no effect to its, magnetic ring/magnetic beads for the common mode signal will show a larger ac synchronous generator motor electric inductance. The use of copper in have a better idea is to get through the copper wire around a few times repeatedly, to increase the inductance. According to it for electromagnetic interference suppression principle, the rational use of its inhibitory effect. Ferrite suppression components shall be installed near the interference electric motor parts sources. For input/output circuit, should as far as possible close to the shielding casing of the inlet and outlet. Of ferrite beads and magnetic beads absorption filter, in addition to should choose high magnetic permeability of a conductive material, but also pay attention to single phase 3 hp motor it. They presented to the high frequency component in a circuit resistance is about ten to several hundred Ω, so its role in the high impedance circuit is not obvious, on the contrary, in a low impedance circuit (such as power distribution, power supply or rf circuit) in use will be very effective.
