What is the difference between standard motors and robotics grade motors?

• sgtnoodle 6y ago
  I would imagine robots like very high torque low speed motors with no backlash. Built in high precision position sensing is also probably nice.

    Yep and they will be brushless motors which means a controller that costs at least $85 per axis (though a $500 motor may have that integrated already).

    Most factories wont pay the extra for absolute-precise-measured in robots. You only get relative precision. So its high precision, but with the robot built in flaw and no compensation formula measured out for the individual robot.

    It's application dependent. If you're making a robot fitting car doors, you want precision and high torque - but you also want high enough speed to keep your cycle times down. And of course you'll want a magnetic brake that can stop your heaviest payload at top speed, in case there's a power cut or the control software crashes. But you don't engage the brakes every time you're stationary. So the robot can stay in one place, you'll need enough cooling that you can apply full torque with a stationary motor indefinitely without any heat worries. And if your robot is industrial? No air holes or fans for you. Gotta find that cooling entirely passively. Oh, and if it wears out after 2 years of 24/7 operation your users will consider that unreliable. They'll do scheduled maintenance - but they'll still be running robots from the floppy disk era.
