●Package Include: 42-34 Stepper Motor with Wiring *3pcs ●SIMAX3D NEMA 17 Stepper motor 42-34 is high torque(42Ncm(60oz.in) ), low self-inductance reactance, responsive and can avoid system error. ●SIMAX3D Pancake motor is made of sturdy and durable metal. The perfect combination of rubber and rotor makes the internal structure more stable. This can reduce the vibration and noise generated when the motor is running. ●Compared with motors of the same thickness and torque, our Nema 17 motor 42-34 resistance value of the stepper motor is lower, effectively reducing the heat generation of the motor. ●The bearings of our stepper motor 42-34 are optimised to ensure better disassembly and longer life. This means you can save on engine replacement or repair costs.
