Stepper motor, 86mm flange(NEMA34), 2 phase, 4.6A, 6.5Nm, 4 leads, 14mm shaft with key. 98mm length
NEMA 34 stepper motor, 86mm flange, 4.6 A/phase, 6.5 Nm / 66.3 kg-cm holding torque, 4 leads, 14mm keyed shaft.
Overview
The M2864T065-14 is a NEMA 34 stepper motor with an 86mm flange and a 98mm body, holding 6.5 Nm / 66.3 kg-cm at standstill - between the M2868T035-14 (3.5 Nm / 35.7 kg-cm) and M2868T085-14 (8.5 Nm / 86.7 kg-cm) in this group.
It draws 4.6 A per phase, needing a drive with headroom above the 2.8 A M2868T035-14 - a Tstep-117X (1.2-7.0 A) or Tstep-168X (1.2-8.0 A) covers it.
Four lead wires bring out one connection per phase, fixed in series at the factory. The 14mm shaft carries a keyway, which lets a coupling drive it positively rather than relying on a set-screw clamp alone - relevant on an axis that sees shock loads or frequent direction reversal, where a keyless shaft can slip under a clamp coupling over time.
For a lighter or heavier axis in the same flange, the M2868T035-14 and M2868T085-14 bracket it in torque, though both wire eight leads rather than this motor's fixed four.

Questions
What drive covers 4.6A?
A Tstep-117X (1.2-7.0A) or Tstep-168X (1.2-8.0A) — needs headroom above the lighter M2868T035-14's 2.8A.
What's the keyway on the shaft actually for?
It lets a coupling drive the shaft positively rather than relying on a set-screw clamp alone — relevant on an axis with shock loads or frequent direction reversal, where a keyless shaft can slip under a clamp coupling over time.
Your other motors in this bracket use 8 leads for series/parallel wiring choice — why does this one only have 4?
This motor's leads are fixed in series at the factory rather than offering that choice — its bracketing siblings (M2868T035-14 and M2868T085-14) do use 8 leads, but this middle one doesn't follow that pattern.
