MAX
Maximum force of the motor (according to data sheet)
L,MAX
Maximum force of the duty cycle that the motor must produce
Maximum current of the motor at maximum force F
MAX
MAX,FMAX
Maximum velocity up to which the motor can deliver the maximum force F
MAX
P
EL,MAX
Electric power drawn by the motor at point (F

friction and eddy currents are ignored.
The sum of the output mechanical power P
MECH
and power loss P
