Remarks:

The frictiontorque is determined via two ways and they do not match; it is determined from the no load current and provided by the vendor. The friction provided by the vendor is lower than determined from no load currrent. Used here is the no load current divided by the torque constant to be safe, so pratical values may be more favourable.
The derating for the magnetstrength is not given so 'worst case' is used of -0.2 %/K for the provided magnetmaterial. This means that the calculated temperature may be inaccurate.
C_th,total is not provided. This means that the time when thermal stability occurs can not be calculated.
The heatsink used for this motor is 4'' x 4'' x 0.125 '' Alu
