STEPPERONLINE Nema 17 Stepper Motor Bipolar L=48mm w/Gear Ratio 50:1 MG Series Planetary Gearbox

Key features

• High torque, Low noise
• The gear ratio is 50:1 and the Max. backlash is 50 arc minutes.
• It's an excellent choice for applications that require good accuracy but low cost.
• As MG series gearbox built-in shaft coupling, so you can change the motor or gearbox easily.

This Nema 17 stepper motor delivers a holding torque of 0.52Nm(73.64oz.in) and features our high-precision MG series gearbox with a 50:1 gear ratio. Unlike the EG series' steel gears, the MG series utilizes durable powder metallurgy gears, offering an optimal balance of precision and cost-effectiveness for your applications. The integrated shaft coupling design allows for easy motor or gearbox replacement, providing flexibility for your projects.
