Stepper motor, 57mm flange(NEMA23), 2 phase, 5.0A, 3.0Nm, 4 leads
NEMA 23 stepper motor, 57mm flange, 5.0 A/phase, 3.0 Nm / 30.6 kg-cm holding torque, 4 leads.
Overview
The M2574T030-8 is a NEMA 23 stepper motor with a 57mm flange, the highest-current and highest-torque motor in the 57mm-flange group in this catalogue.
It draws 5.0 A per phase and holds 3.0 Nm / 30.6 kg-cm at standstill, suited to a loaded router or engraver axis, or a lighter lathe axis, where the M2574T013-6.35 or M2574T022-8 would be undersized. At 5.0 A it needs a drive with headroom above that figure - the Tstep-117X or Tstep-168X range (up to 7.0-8.0 A) rather than the smaller Tstep-484.
Four lead wires bring out one connection per phase, fixed in series at the factory.
For a lighter axis where 3.0 Nm / 30.6 kg-cm is more than needed, the M2574T022-8 and M2574T013-6.35 cover the same 57mm flange at lower current and cost, sharing the same shaft diameter and mounting pattern. All three run at 4 lead wires with fixed series wiring, so the wiring approach doesn't change across the group either.

Questions
Is this the top of the M2574 range?
Yes — the highest-current and highest-torque motor in the 57mm-flange group in this catalogue.
What drive does 5.0A actually need?
A drive with headroom above that figure — the Tstep-117X or Tstep-168X range (up to 7.0-8.0A) rather than the smaller Tstep-484.
If 3.0 Nm is more than I need, is there a lighter option in the same flange?
Yes — the M2574T022-8 and M2574T013-6.35 cover the same 57mm flange at lower current and cost, sharing the same shaft diameter and mounting pattern.
