Predict the temperature of the stator winding in an
The data comes from a permanent magnet synchronous motor on a test bench. The PMSM
represents an electric car prototype and multiple sensors are present on the bench.
Multiple driving cycles were performed, randomly varying speed and torque to imitate
real world driving.
The following info was measured:
- ambient temperature
- coolant temperature
- rotor temperature
- temperature from multiple parts of the stator
- permanent magnet temperature
- voltage (d and q-component)
- current (d and q-component)
- motor speed
- torque (induced by current)
The most interesting features are the torque and the different stator and rotor
temperatures. Especially torque that can't be easily or economically measured in a
In this dataset, we will take the stator winding temperature, group it in 5 different
intervals, and use the other columns as input features. That way, we are able to
transform the problem from a regression to a classification task.
With the help of our algorithms, we are able to obtain very high accuracy. Which means,
given some driving conditions we can predict what the temperature will be.
