Remarks:

The velocity dependant friction is not provided so calculation is done with 0. This means that the current may be larger than calculated and the necessary power of the motor may be larger.
The frictiontorque is determined from the slope of the 100% DC-line in the torque-speed-characteristic. This means the value 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: C
