Silent Jack Posted June 17, 2011 Report Share Posted June 17, 2011 When building and powering a solenoid, is more voltage/capacitance better for a strong fast field generation? Or is it something of a balance between the two? Secondly, how much does saturation come into play were the plunger portion is concerned?

Hero999 Posted June 18, 2011 Report Share Posted June 18, 2011 The capacitance should be as low as possible because it slows it down and can cause resonance.Saturation is the point at which the iron core becomes saturated so an increase in current results in less of an increase in field. When core saturation occurs, the inductance drops to the point where the core is effectively not there. Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted June 22, 2011 Author Report Share Posted June 22, 2011 So oversaturation could result in damage to the circuit through blowby? Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 22, 2011 Report Share Posted June 22, 2011 What does blowby mean?At DC, the current through a coil is determined by the series resistance not the inductance. Whether the coil is damaged or not depends on the power dissipation (P = I2R) and its ability to dissipate heat. Quote Link to comment Share on other sites More sharing options...
