# Dataset Description

<h2>Data Set Details:</h2>
A comprehensive csv files containing all measurement sessions and features. Each row represents one snapshot of sensor data at a certain time step. Sample rate is 2 Hz (One row per 0.5 seconds). Distinctive sessions are identified with "profile_id".


<h2><strong>Feature set:</strong></h2>

<strong>ambient</strong>
<p>Ambient temperature as measured by a thermal sensor located closely to the stator.</p>
<strong>coolant</strong>
<p>Coolant temperature. The motor is water cooled. Measurement is taken at outflow.</p>
<strong>u_d</strong>
<p>Voltage d-component</p>
<strong>u_q</strong>
<p>Voltage q-component</strong>
<strong>motor_speed</strong>
<p>Motor speed</p>
<strong>torque</strong>
<p>Torque induced by current.</p>
<strong>i_d</strong>
<p>Current d-component</p>
<strong>i_q</strong>
<p>Current q-component</p>
<strong>pm</strong>
<p>Permanent Magnet surface temperature representing the rotor temperature. This was measured with an infrared
thermography unit.</p>
<strong>stator_yoke</strong>
<p>Stator yoke temperature measured with a thermal sensor.</p>
<strong>stator_tooth</strong>
<p>Stator tooth temperature measured with a thermal sensor.</p>
<strong>stator_winding</strong>
<p>Stator winding temperature measured with a thermal sensor.</p>
<strong>profile_id</strong>
<p>Each measurement session has a unique ID. Make sure not to try to estimate from one session onto the other as they are strongly independent.</p>
