Precise and Repeatable Speed and Positioning
Stepper motors are DC motors that move in discrete steps. They are prized for their precise speed control and their repeatable positioning ability. Stepper motors can be found in all sorts of applications ranging from clocks to robots and CNC machines.
Stepper motor come in many different sizes, shapes and electromechanical specifications. For more details on selecting and using stepper motors, see the All About Stepper Motors Guide
in the Learning System.

Precise repeatable positioning
Precise speed control
Excellent low-speed torque
Excellent 'holding torque' to maintain position
May need encoder or limit switch to establish a reference position
Subject to missed steps if overloaded
