What are stepper motors good for?

[Admin]

• Positioning –
  

Since steppers move in precise repeatable steps, they excel in applications requiring precise positioning such as 3D printers, CNC, Camera platforms and X,Y Plotters. Some disk drives also use stepper motors to position the read/write head.

• Speed Control –
  

Precise increments of movement also allow for excellent control of rotational speed for process automation and robotics.

• Low Speed Torque -
  

Normal DC motors don't have very much torque at low speeds. A Stepper motor has maximum torque at low speeds, so they are a good choice for applications requiring low speed with high precision.

Except to the mentioned above. What are the stepper motor good for? Is there any other answer?
