Many netizens asked, what material is better for the motor shaft, stainless steel or 45# carbon steel? Which material has a better electromagnetic effect? The following editor will answer for everyone.
The motor shaft is generally made of 45# steel. High-power can be quenched and tempered with 40cr, high-speed and high-precision motor is 38CrMoAlA, I have never heard of T8. If you understand, you can talk about it, and if you don’t understand, don’t cheat others. The characteristics of materials such as T8 are high hardness after quenching and good wear resistance, but they are not resistant to torque. It is easy to be deceived by impact. In the future, if the motor shaft made of T8 is really used, the torque is large and the shaft is broken. , Can you afford this responsibility?
In addition, the material of the shaft of an ordinary motor has no effect on the electromagnetic, or it does not matter whether it has an effect, because the electromagnetic force acts on the iron core of the rotor (to be precise, the largest circle of the iron core is most obvious). Instead of on the axis.
