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 permanent magnet 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 studio, given some driving conditions, we can predict what the
temperature will be, given a confidence interval.
