Re: Have servo drives eliminated ball-detent torque limiters from new OEM designs?

I agree that servos have become much more sophisticated, so in the lower torque applications there is less of a need for the old style torque limiter but there are still many applications that aren't driven by servos especially high torque applications like conveyors or mining machines. Also many times it depends upon the reduction being used and how fast the motor would see the torque spike. In those instances the torque limiter is located very close to the final drive point versus further up the drivetrain near the motor.
