ME286T040EC Stepper motor, close loop, 4.5Nm
Closed-loop stepper motor, 86mm flange, 4.2 A/phase, 4.5 Nm / 45.9 kg-cm holding torque, built-in encoder.
Overview
The ME286T040EC is a closed-loop stepper motor with an 86mm flange, the lowest-current and lowest-torque motor in this catalogue's ME286 easy-servo range.
It draws 4.2 A per phase (0.41 ohm, 2.82 mH) and holds 4.5 Nm / 45.9 kg-cm at standstill, at a standard 1.8 degree step angle, weighing 2.46 kg. 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 more torque in the same 86mm flange, the ME286T080EC and ME286T120EC in this range step up to 8.5 Nm / 86.7 kg-cm and 12 Nm / 122.4 kg-cm.

Questions
This is the entry-level one in the range — is it still a real closed-loop motor, or a cut-down version?
A real one — it's just the lowest-current, lowest-torque motor in the ME286 range, still 4.5 Nm / 45.9 kg-cm with the same built-in encoder as its siblings.
Does buying this motor include the drive and cables?
No — motor only. The SDW86 drive and the encoder/power cables (EC1-030/EC1-080, PC1-030/PC1-080) are all sold separately.
If 4.5 Nm isn't enough, what's available in the same flange?
The ME286T080EC (8.5 Nm / 86.7 kg-cm) and ME286T120EC (12 Nm / 122.4 kg-cm) step up in the same 86mm flange.
