3D printer extruder steps motor for j-head 42 * 42 * 23mm Bowden-head, this stepper motor has increased the overall speed by 15% to 25% compared to traditional motors. circuit boards inside the motor have been upgraded to ensure the stability of the motor structure and achieve the ideal smooth rotation effect, also avoid system errors and achieve accurate results. and it adopts strong 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. The bearing is optimized for short, repetitive movements and offers even better disassembly and assembly for a long. This saves you the cost of the motor. it can achieve a lower resistance value compared to motors of the same thickness and torque. This significantly increases the thermal conductivity of the motor. This effectively reduces the increase in temperature.
