Does temperature affect motor current?
Yes, for ordinary conductors, the higher the temperature, the lower the resistance, and thus the greater the current
2# l-zhi-q: Is the 2nd floor incorrect? The resistance of most conductors increases as the temperature rises.
The higher the temperature, the harder it is for the motor to dissipate heat; the motor current also increases, increasing the risk of the motor burning out.
The higher the temperature, the greater the winding resistance, the lower the current, and the motor’s power may not be sufficient to meet the demands of the load.
The higher the temperature, the harder it is for the motor to dissipate heat; the lower the current-carrying capacity of the cables, and the greater the risk of the motor burning out
The higher the temperature, the greater the resistance. At the rated power, the current does not decrease; as a result, more heat is generated in the windings. The higher the temperature, the greater the resistance, creating a vicious cycle. When the temperature exceeds the level required by the motor’s insulation standards, the insulation quality declines, leading to short circuits
The higher the temperature, the greater the DC impedance of the windings, which in turn increases the electrical power consumed by the windings. This leads to severe heating of the motor, and such a vicious cycle can result in motor burnout.
