Four NEMA 34 closed-loop stepper motors, one HBS860H driver and one 60V 400W power supply.

How much torque does each motor produce?

The set is rated 4.5 to 12 Nm at 6 A, depending on the motor in the set.

Can I run all four motors from the included driver?

No. The set includes one HBS860H driver, so a four-axis build needs three more drivers matched to the motors.

Is this a drop-in replacement for open-loop NEMA 34 motors?

The frame and shaft fit NEMA 34 mounts, but you must wire the encoder to the HBS860H and tune it, which open-loop setups do not need.

What machines is it meant for?

CNC machines, 3D printers, carving machines and general automation projects that need precise positioning.

Does closed loop really stop missed steps?

Encoder feedback lets the driver detect and correct position error, which greatly reduces missed steps compared with open-loop drives, though it is not a full servo system.

Our take on the Nema 34 Closed Loop Stepper Motor Set, 4 Pack

A four-pack of NEMA 34 closed-loop stepper motors bundled with an HBS860H driver and a 60V 400W power supply. Encoder feedback lets the driver correct position errors in real time, which cuts missed steps compared with open-loop steppers. Torque runs 4.5 to 12 Nm at 6 A, putting it in the range of a mid-size CNC router or automation axis. It suits builders who want closed-loop reliability without switching to servo drives, though it is heavier and more complex to wire than an open-loop kit.

Best forCNC router and mill builders upgrading from open-loop steppersAutomation and motion-control projects needing encoder feedbackCarving and engraving machines with NEMA 34 mountsBuilders who want motors, driver and supply in one set

Pros

Encoder feedback reduces missed steps under load
HBS860H driver included, so motor and driver are matched
60V 400W supply covers the driver's voltage needs
4.5 to 12 Nm torque range handles mid-size axes
Four motors in one set for multi-axis builds

Cons

Closed-loop wiring is more involved than open-loop
NEMA 34 frame is bulky and heavy for small machines
One driver and one supply for four motors means extra drivers are needed for multi-axis use
Setup requires tuning the driver to each motor
