Calculating the braking energy in case of a linear motor:
Where:
m
M
: Motor mass [kg]
m
L
: Mass of the load [kg]
v
M
: Motor speed before deceleration [m/s]
g = 9.81 m/s
2
h
1
: Height before deceleration [m]
h
2
: Height after deceleration [m]
I
M
: Motor current during deceleration [A]
R
Ph
: Resistance of the motor [ ]
t
d
: Delay time [s]
F
L
: Friction power of the motor [N]
If the calculation described above cannot be carried out because of
missing values, a good starting value for the capacitor is 10,000 µF /
100 V.
