- Details: https://sigmanortec.ro/en/llms/p/2435.md
- Price: 538.33 RON
- Availability: In stock; 1-2 zile
- Reference: 88257 · EAN: 5948281052330
- Specifications: Input Voltage: 12 - 36 VDC; Gear ratio: 27:1; Current per phase: 1.68 A; Motor frame size: NEMA 17

Ideal for applications that require high torque and smooth motion at low speeds, such as 3D extruders, CNC machines, or robotic arms. The 27:1 planetary gearbox provides an output step of 0.067° and backlash under 1°, and the 1.68A bipolar motor works with STEP DIR drivers at 12-36V, with an 8 mm shaft and D-cut for secure mounting.
The Nema 17 stepper motor with integrated planetary gearbox is a compact and efficient solution for applications that require high torque at low rotational speeds. The motor is bipolar, with a step angle of 1.8° per pulse applied directly to the rotor, equivalent to 0.067° at the gearbox output shaft, thanks to the 26.85:1 reduction ratio.
