Product Description

112mm 0.8ohm 3.5mH NEMA23 4.2A 2.8NM CLOSE LOOP STEPPER MOTOR FOR For 3d Printer

      This enables servo motors to be used with gearboxes to deliver much higher torque at useful speeds. They also deliver more consistent torque across the speed range of the motor. Unlike stepper motors, they do not have holding torque per se.
