Editing Stepper motor (section)

===Advantages===
*Low cost for control achieved
*High torque at startup and low speeds
*Ruggedness
*Simplicity of construction
*Can operate in an open loop control system
*Low maintenance (high reliability)
*Less likely to stall or slip
*Will work in any environment
*Can be used in robotics in a wide scale.
*High reliability
*The rotation angle of the motor is proportional to the input pulse.
*The motor has full torque at standstill (if the windings are energized)
*Precise positioning and repeatability of movement, since good stepper motors have an accuracy of 3–5% of a step and this error is non-cumulative from one step to the next.
*Excellent response to starting/stopping/reversing.
*Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
*The motor's response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
*It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
*A wide range of rotational speeds can be realized, as the speed is proportional to the frequency of the input pulses.
