Remarks:

  1. 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.
  2. The frictiontorque is determined from the slope of the 100% DC-line in the torque-speed-characteristic. This means the value may be inaccurate.
  3. The vendor has not provided magnetmaterial. The derating for the magnetstrength is not given so 'worst case' is used of -0.2%/K. This means that the calculated temperature may be inaccurate.
  4. Cth,total is not provided. This means that the time when thermal stability occurs can not be calculated.
  5. The heatsink used for this motor is 6 '' x 6 '' x 1/4 '' Alu
