T85H156-6204 NEMA-34 4 Wire Motor
NEMA 34 stepper motor, 156mm body, 6.2 A/phase, 12.2 Nm / 124.0 kg-cm holding torque, 4 leads.
Overview
The T85H156-6204 is a NEMA 34 stepper motor with a 156mm body, the highest-torque and highest-current motor in the T85H series in this catalogue.
It draws 6.2 A per phase (0.75 ohm, 9.0 mH) and holds 12.2 Nm / 124.0 kg-cm at standstill - more than double the T85H90-5504's 5.88 Nm / 60.0 kg-cm. At 6.2 A it needs a drive with real headroom above that figure; the Tstep-168X (1.2-8.0 A) is the fit, where a Tstep-117X (up to 7.0 A) would be running at its limit.
Four lead wires bring out one connection per phase, fixed in series at the factory.
At 156mm this is the longest motor in this catalogue's NEMA 34 range - check physical clearance and shaft loading before fitting one on an existing mount sized for a shorter motor. Where 12.2 Nm / 124.0 kg-cm is more torque than needed, the T85H90-5504, T85H118-4208 and shorter T85H motors cover less demanding axes.

Questions
Is this the most torque you offer in a NEMA 34 frame?
Yes — the highest-torque and highest-current motor in the T85H series, more than double the T85H90-5504's torque.
What drive do I need at 6.2A?
The Tstep-168X (1.2-8.0A) — a Tstep-117X (up to 7.0A) would be running right at its limit.
I have a mount already sized for a shorter T85H motor — will this drop in?
Check first — at 156mm this is the longest motor in the catalogue's NEMA 34 range, so verify physical clearance and shaft loading before fitting it on a mount built for a shorter one.
Would this be overkill for a lighter axis?
Likely — the T85H90-5504, T85H118-4208 and other shorter T85H motors cover less demanding axes.
Can I rewire this for series/parallel like the 8-wire T85H motors?
No — four leads, fixed in series at the factory.
