What is its value corrected to 40°C. the correction factor for 70°C is 8.0.
Observed resistance at 70°C – 15 MΩ.
Temperature correction factor – 8.
Rm = kt * Rt kt – correction factor.
Rm = 8 * 15 Rt – resistance measured at +°C.
Rm = 120 MΩ. Rm – corrected value to 40°C
The IR of DC motor corrected to 40°C is 120 MΩ
