Limit data
F
MAX
Maximum force of the motor (according to data sheet)
F
L,MAX
Maximum force of the duty cycle that the motor must produce
I
MAX
Maximum current of the motor at maximum force F
MAX
v
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

. Losses due to
friction and eddy currents are ignored.
Comment:
The sum of the output mechanical power P
MECH
and power loss P
V
is the electric power
drawn by the motor P
