Will this fit an Ender 3 or CR-10?

No, not as a direct replacement. Those printers use NEMA 17 motors driven at 24V, while this is a NEMA 52 motor with an AC mains driver. Fitting it means rebuilding the machine around it.

What does the brake do?

It clamps the shaft when power is removed, so a vertical axis or heavy gantry does not drop. The brake releases when energized, so it needs a control signal and supply of its own.

Do I need a separate power supply?

No. The DM3922 driver takes AC 110-220V directly from the wall. You still need low-voltage logic power and step/dir signals from your controller.

Is it quieter than a two-phase motor?

Generally yes. Three-phase motors have smoother torque delivery and less mid-range resonance than comparable two-phase steppers, so they tend to run quieter at speed.

What comes in the kit?

The motor with its integrated brake and the DM3922 driver. Cables, connectors and a brake control circuit are not included, so plan for those separately.

Our take on the Beefy Torque 3-Phase Stepper Motor Kit with Brake

This is a NEMA 52 (130 mm frame) three-phase stepper motor bundled with a brake and a DM3922 driver that runs on AC 110-220V mains. The brake holds the shaft when power drops, which matters on Z axes and vertical loads where gravity would otherwise let the carriage fall. It is aimed at CNC routers, mills, lathes and heavy 3D printer builds rather than desktop printers. The listing's claim of Ender 3 and CR-10 compatibility is misleading: those printers use small NEMA 17 motors and low-voltage drivers, so this kit does not bolt on or wire up without a full rebuild.

Pros

Integrated brake holds the shaft when power is cut
Three-phase design runs smoother and quieter than two-phase motors at speed
DM3922 driver accepts AC 110-220V directly, no separate power supply
NEMA 52 frame gives high holding torque for heavy gantries
One kit covers motor, brake and driver

Cons

Not a drop-in for Ender 3, CR-10 or A8 despite the compatibility claim
NEMA 52 is far larger and heavier than the NEMA 17 motors those printers use
Brake needs its own control signal and wiring beyond the step/dir lines
Mains-voltage wiring demands care and a proper enclosure
Little independent user feedback available for this specific kit
