WARNING:
The use of extra-quick fuses FU1/2 is recommended to protect the internal
power module in case of undesired external short-circuits. Comply with the max.
prescribed value for I

The L1 switching impedance is 35A/150
µ
H
(ELETTRONICA SANTERNO code: IM0100354).
The current FF form factor can be obtained by measuring the effective value
[ ]

e
I
of the
alternate component of the current absorbed by the motor (with a A.C. instrument with
real effective value) and the mean value
I
m
of the same current (with a D.C. instrument).
The result is given by the following formula:

Since the motor and drive heating, as well as the periodical maintenance operations on
brushes and manifold, depend on the form factor, apply the levelling inductance L2 so
as to keep the form factor value as close as possible to 1.
Through the following formula, you can get the L2 mH value of the levelling inductance
to be inserted, assuming the motor one is negligible, using the desired form factor FF
value, the supply alternate voltage
