Remarks:

  1. The vendor has not provided magnetmaterial. The derating for the magnetstrength is not given so 'worst case' is used of -0.2%/K. The maximum allowed temperature is not given so 'worst case' is used of 373 K. The thermal resistance Rth,total is determined from given stallcurrent and derived winding resistance R. This means that the calculated temperature may be inaccurate.
  2. The winding resistance R is determined from the steepness of the motor so the value may not be accurate. This means that the calculated current and voltage may be inaccurate.
  3. Cth,total is not provided. This means that the time when thermal stability occurs can not be calculated.
  4. The vendor has not provided information about a heatsink for the given thermal information.
