stepper motor in the Full Step Mode.
The calculations consider three different condi-
tions of heatsinking: the package with minimum
dissipating copper area on the p.c.b. (Rthj-amb =
55
°C); the copper side of 6 cm2 (Rthj-amb =
40
°C/W - See Fig. 34) and the additional heatsink
(Rthj-amb = 30
°C/W).
