Remarks:

The frictiontorque is determined from the slope of the 100% DC-line in the torque-speed-characteristic. This means the value may be inaccurate.
The derating for the magnetstrength is not given so 'worst case' is used of -0.2 %/K for the provided magnetmaterial. The maximum allowed temperature is not given so 'worst case' is used of 373 K. R_th,total is determined from given stallcurrent and not accurate because temperature Θ_max is unknown. 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 vendor has not provided information about a heatsink for the given thermal information.

The quality and completeness of the supplied information has quality index: D

This quality index is determined by specAmotor.com. Here is described what the quality index is.
