CALCULATION TOOL FOR THE RELATIONSHIP BETWEEN COIL TEMPERATURE AND RESISTANCE, ESPECIALLY FOR SOLENOIDS AND ROTARY SOLENOIDS

calculation of the temperature rise based on change of resistance
Formula: Δt = (R2 - R1)/R1*(1/α+t1)+t1-t2
coil resistance at start R1 [Ω]
coil resistance at end R2 [Ω]
ambient temperature at start t1 [°C]
ambient temperature at end t2 [°C]
temperature rise of the coil Δt [°]
temperature of the coil at end ts [°C]
 

calculation of the coil resistance based on temperature change of the coil
Formula: R2 = R1*(1+(t-t1+t2)/(1/α+t1)
temperature of the coil at end ts [°C]
ambient temperature at start t1 [°C]
ambient temperature at end t2 [°C]
coil resistance at start R1 [Ω]
temperature rise of the coil Δt [°]
coil resistance at end R2 [Ω]

***  An important note:
We have tested our tools carefully. Nevertheless, we cannot exclude the possibility that errors have crept in with the large number of formulas and links. Also the accuracy of the calculations will depend on the proper use of tables and the accuaracy of the input by the user.  Therefore: All calculations are made at your own risk.
