Stepper Motor vs Servo Motor
Stepper Motor vs Servo Motor
(OP)
Hi all,
What's the main differences between stepper and servo motors and what applications might they be used?
God bless,
Phil.

That's a consequence of the control approaches described above. A closed-loop control system wants linear, or quasilinear behavior, which obviates a coggable motor.
A stepper motor uses the cogging as a means of provide repeatable responses to stepping commands and to stay in the commanded position.

Servos generally can provide higher speeds, torques, and accelerations than steppers.

My advice is to only use steppers for very low-torque, rotational applications, like rotating a small part or free machine member. Yes, I know that they make big stepper brutes, but I have had lots of problems with such applications in my 22 years' experience. Anything that requires torque or acceleration of even moderate loads usually will need a servo. The cost savings of the stepper will not be worth the headaches you will have with it.

Some high performance servo motors have no iron in the active portion of the motor, resulting in zero cogging.
