Silver NEMA17 geared stepper motor with detachable wires and flatted shaft

3D Maker World

3D Maker World Kysan 1040222 Geared NEMA17 Stepper Motor 5.2:1 3d printers accessory

SKU CH-ESX2-45YYK

A NEMA17 geared stepper motor with a 5.2:1 ratio delivering 88 N-cm torque for extruder drives, featuring a compact design and 1830 mm detachable wires for easy management

  • High torque of 9 Kg-cm drives demanding extruders
  • 2:1 gear ratio multiplies motor force for heavy loads
  • Detachable 1830 mm wires simplify cable routing
  • Compact NEMA17 body fits tight printer frames
  • 8 mm flatted shaft secures couplers without slipping

Kysan 1040222 Geared NEMA17 Stepper Motor

This NEMA17 geared stepper motor provides massive torque of 9 Kg-cm (88 N-cm, 125 Oz/in) to drive your extruder. A 5.2:1 gear ratio multiplies holding force while keeping the body compact for tight printer frames. The detachable 1,830 mm wire harness simplifies cable routing and maintenance.

Suited For Direct-Drive Extruder Upgrades

Makers converting a Bowden printer to direct drive or replacing a worn stock motor gain the torque needed for consistent filament grip. Builders who need a standard NEMA17 shaft without a gearbox, or who require a different gear ratio for speed-critical axes, should look at other motor types.

5.2:1 Gear Ratio With 8 mm Flatted Shaft

The 5.2:1 reduction delivers 9 Kg-cm output torque from a 2.6 V, 1 A two-phase winding. An 8 mm flatted shaft mates with common extruder gears and couplers, while 2.6 Ω phase resistance and 3.2 mH inductance match typical 3D printer driver settings.

Questions about this item

Will the 8 mm flatted shaft need periodic replacement?

The 8 mm flatted shaft is integral to the Kysan 1040222 motor body and is not a consumable part; only the detachable 1 830 mm wire harness might be swapped if damaged.

What limits continuous operation of the 5.2:1 geared NEMA17 stepper?

With 1 A per phase at 2.6 V and 2.6 Ω resistance, winding heat is the first limit during sustained use; the 100 MΩ insulation rating at 500 VDC defines the thermal ceiling.

How much heat and noise does the 9 Kg-cm geared motor produce all day?

The 5.2:1 gearbox multiplies torque to 9 Kg-cm while reducing output speed, so the motor runs cooler and quieter than a direct-drive NEMA17 at equivalent load.
