ME286T120EC : Stepper motor, close loop 12.0Nm
Closed-loop stepper motor, 86mm flange, 6.0 A/phase, 12 Nm / 122.4 kg-cm holding torque, built-in encoder.
Overview
The ME286T120EC is a closed-loop stepper motor with an 86mm flange, the highest-current and highest-torque motor in this catalogue's ME286 easy-servo range.
It draws 6.0 A per phase (1.72 ohm, 8.3 mH) and holds 12 Nm / 122.4 kg-cm at standstill, at a standard 1.8 degree step angle, weighing 5.32 kg - noticeably heavier than the ME286T040EC's 2.46 kg, since the extra torque needs more magnetic material in the same flange diameter. Unlike an open-loop stepper motor, it carries a built-in encoder on the back of the shaft, which is what lets a closed-loop drive detect and correct a missed step instead of the motor silently stalling under a sudden load.
That encoder only does anything paired with a closed-loop drive built to read it - this catalogue's SDW86, rated for 86mm frame motors and matching this motor's flange directly. The encoder and power connections between the two are separate cables (EC1-030/EC1-080 and PC1-030/PC1-080 in this catalogue), sold apart from both the motor and the drive.
For a lighter axis where 12 Nm / 122.4 kg-cm is more than needed, the ME286T040EC and ME286T080EC cover the same flange at lower current and cost.

Questions
Will the built-in encoder do anything if I run this on a regular open-loop drive?
No — the encoder only does anything paired with a closed-loop drive built to read it, such as this catalogue's SDW86. On an open-loop drive, it's just along for the ride.
Does this include the drive and connecting cables, or is it motor-only?
Motor only — the SDW86 drive and the encoder/power cables between them (EC1-030/EC1-080, PC1-030/PC1-080) are all sold separately.
This weighs a lot more than the smaller ME286 motors — why?
The extra torque needs more magnetic material packed into the same flange diameter — 5.32 kg here versus the ME286T040EC's 2.46 kg.
Which drive is this actually meant to pair with?
The SDW86 — rated for 86mm frame motors and matching this motor's flange directly.
