?Faster and More Accurate?: Usongshine stepper motor has increased the overall high torque speed by 15% to 25% over conventional motors. We have upgraded PCBs inside the engine to ensure the stability of the motor structure and to achieve the ideal uniform rotation effect, also to avoid system errors and achieve accurate results. ?Low noise?: Stepper motor uses sturdy and durable metal. The perfect combination of rubber and rotor makes the inner structure more stable. This reduces vibration and noise when the engine is working. ?High-quality bearing?: The bearing is optimized for short, repetitive movements and offers even better disassembly and assembly for a long service life. This means that you can save on the cost of replacing or repairing the engine. ?Low Resistance?: Usongshine stepper motor can get a lower resistance value compared to motors of the same thickness and torque. This considerably increases the thermal conductivity of the motor. This effectively reduces the increase in temperature. ?24 Month Warranty?: Usongshine is a brand specializing in the design and manufacture of 3D printing supplies. Each nema 17 stepper motor has undergone a rigorous quality control ex works. Usongshine can carry out a 24-month quality assurance for every stepper motor.
