Behavioural mixed-signal modelSOYO SY42STH38-1684Anema17_stepper
Stepper motor NEMA 17 (1.8°, 1.68 A)
Bipolar hybrid stepper motor, 200 full steps per revolution, 1.65 Ω and 3.2 mH per phase, 1.68 A rated current, holding torque 36 N·cm. Phase A: black / green, phase B: red / blue. Drive it with a current-limiting driver (A4988, DRV8825). The shaft turns in the schematic with the field of the two coils.
