This is one of the most popular stepper motor in Nema 17 size, it with 1.8deg step and size 42x42x34mm.
This stepper motor is ideal for the RepRap Prusa, Mendel 90, Rostock and similar 3D printers, as well as CNC and robotics applications. Nema 17 datasheet is as the below.
The motor coils are made of pure copper enamelled wire, with excellent workmanship and evenly distributed copper wires, resulting in a lower temperature rise of the motor and no deformation or noise over long periods of time.
Silicon steel rotor, using international silicon steel material bearings, the introduction of German technology to build from, the surface is coated with imported rotor rubber, textile silicon steel oxidation to reduce the surface burr after grinding, than other brands of motor torque, more stable output, lower noise, longer life.
Uniform rotation speed without loss of step. The PCB is reinforced inside the motor and a unique stator process is used to ensure that the motor stator teeth are evenly ground and clean, with a high precision bore, so that the speed is stable and accurate without losing steps during work.
Stable structure without jamming. The surface of the motor rotor is coated with imported epoxy resin, which seals the rotor as a whole and is cured at high temperature. After the rotor is eliminated and processed in the outer garden, it is not easy to have iron pins and other processing residues in the tooth grooves, and the motor is stable for a long time without the risk of jamming.
Stable rotation speed and low noise. The motors are Kossel, Prusa l3, Ultmaker and corexy motors with high overall stability, uniform speed and low noise, so that users can buy with confidence.
