M2864T045-14 , 86mm flange(NEMA34), 2 phase, 4.5 Nm
NEMA 34 stepper motor, 86mm flange, 4.5 Nm / 45.9 kg-cm holding torque, 4 leads, 14mm keyed shaft.
Overview
The M2864T045-14 is a NEMA 34 stepper motor with an 86mm flange, holding 4.5 Nm / 45.9 kg-cm at standstill - between the M2868T035-14 (3.5 Nm / 35.7 kg-cm) and M2864T065-14 (6.5 Nm / 66.3 kg-cm) in this catalogue's 86mm-flange group, consistent with its price sitting between those two as well.
Its model number places it in the same 2864-prefix family as the M2864T065-14 rather than the 2868-prefix M2868T035-14/M2868T085-14 pair - confirmed by its four fixed lead wires and 14mm shaft with a keyway, the same wiring and shaft style as the M2864T065-14, not the eight-wire arrangement the 2868-prefix motors use. The keyway lets a coupling drive the shaft positively rather than relying on a set-screw clamp alone, useful on an axis that sees shock loads or frequent direction reversal.
Phase current is not confirmed for this SKU - no datasheet exists for this specific torque point, and estimating a figure between its siblings' currents would be inventing a spec rather than sourcing one. Given the flange, lead count and torque bracket, a drive in the Tstep-117X or Tstep-168X range (1.2-7.0 A or 1.2-8.0 A) is a reasonable starting point, the same range that covers both the M2868T035-14 and M2864T065-14, but should be confirmed against the motor's actual nameplate before ordering.
For a lighter or heavier axis in the same flange, the M2868T035-14 and M2864T065-14 bracket it in torque.

Questions
What's the phase current, so I can size a matching drive?
Not confirmed for this SKU — no datasheet exists for this specific torque point, and estimating a figure between its siblings' currents would be inventing a spec rather than sourcing one. A drive in the Tstep-117X or Tstep-168X range (1.2-7.0A or 1.2-8.0A) is a reasonable starting point — the same range that covers both siblings — but confirm against the motor's actual nameplate before ordering.
If the current isn't confirmed, how do you know the torque is actually 4.5 Nm?
The torque figure is confirmed separately — via the model number itself, which places this in the same 2864-prefix family as the M2864T065-14 (matching its four leads and 14mm keyed shaft), consistent with its price sitting between its two bracketing siblings too.
Why 4 leads and a keyed shaft instead of the 8-wire style some of your other NEMA 34 motors use?
Because it's in the 2864-prefix family (same as the M2864T065-14) rather than the 2868-prefix pair, which uses 8 wires. The keyway lets a coupling drive the shaft positively rather than relying on a set-screw clamp alone — useful on an axis with shock loads or frequent direction reversal.
If this torque is more or less than I need, what's available in the same flange?
The M2868T035-14 (3.5 Nm) for less, or the M2864T065-14 (6.5 Nm) for more — both in the same 86mm flange.
