Steppers have a higher precision to a servos higher speed and torque (but torque that’s not constant.)
Just trying to understand this. Then how come all CNC precision machines use a servo instead of a stepper? I mean there are some ridiculously accurate machines that can position itself over and over varying under a micron (<.001mm) but the manufacturers choose servo over stepper. Is it for the sake of holding torque that servos have to be used over steppers?
NHS stands for National Health Service.
If I had to take an educated guess, it is the absurdly immense pressure for academic and career success. Basically through one’s entire childhood and early-adult life. A child’s day would be something like public school from morning to afternoon and private tutoring after that until night time. Rince and repeat with an ever growing pressure for an acceptance into a highly rated university.
And on top of that, incredible wealth inequality.
So from childhood until death it all seems like constant pressure to become excellent. Seems like life would be hopeless if one struggles with the academics and fails to secure a career.
A total of 39,453 people killed themselves from 2020 to 2022, according to data from the health ministry and the Korea Disease Control and Prevention Agency submitted to Rep. Baek Jong-hean of the ruling People Power Party.
Apparently the party is South Korean so I presume the stats are just for South Korea.
I see a two post height gauge as well.
It seems like the argument is that at the lower price bracket, stepper motors offer higher performance than what a equivalently priced servo+encoder+controller combo can perform.
I felt like what I was reading in this thread wasn’t matching up with that I see out in industry… concerns about ‘price’ didn’t come up until your post.
Diamond turning machines are inherently low torque, low speed, AND nanoscale operations which uses servos for driving its respective axis. See precitech -youtube and in stark comparison Roeder’s 5axis optical mold machining. Wire EDM’s were all driven by servo motors until linear motors became popular. Even those famous JingDiao test samples are made on machines driven by servos.
