steps
Minimum allowed motor coil
resistance
0.4 - - Ohm
If resistance is lower it
should be extended with
inductor or with resistor/re-
sistor wire.
Minimum allowed motor coil’s
inductance
200 - - uH
If inductance of the motor
coil is lower, it should be
extended with series coil for
correct operation.
