0.9° 1.68A 5mm Round Shaft 40mm Nema 17 Stepper Driver

0.9° 1.68A 5mm round shaft 42mm 40mm Nema 17 Hybrid high precision Stepper Motor

2 phase hybrid stepper motor is a kind of hybrid motor. 2 phase hybrid stepper motor is composed of stator and rotor. The common stator has 8 poles or 4 poles, and a certain number of small teeth are evenly distributed on the pole surface; the upper pole coil can be energized in two directions. Its rotor is also composed of two pieces of teeth evenly distributed on the circumference. The two teeth are staggered by half a pitch. There is an annular permanent magnet with axial magnetization between the two teeth.
