Nema 11 Stepper Motor with Gearbox Gear Ratio 14:1 & Magnetic Encoder 1000PPR(4000CPR)

This Nema 11 geared motor is the Joint 4 motor in AR4 kit. It is integrated with a planetary gearbox of 14:1 gear ratio and a very thin and cost-effective magnetic incremental encoders with 3 channels and 1000PPR(4000CPR) resolution. It's also a good solution to applications that with limited space but need low speed and/or high torque.
