Every motor converts power. Electric motors convert electricity into motion. Stepper motors convert electricity into rotation. Not only does a stepper motor convert electrical power into rotation, but it can be very accurately controlled in terms of how far it will rotate and how fast.
Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn. The number of pulses the motor turns is equal to the number of pulses fed into the driver. The motor will spin at a rate that is equal to the frequency of those same pulses.
Stepper motors are very easy to control. Most drivers are looking for 5 volt pulses which just so happen to be the voltage level of most integrated circuits. You merely need to design a circuit to output pulses or use one of ORIENTAL MOTOR's pulse generators.
One of the most remarkable features of stepper motors is their ability to position very accurately. This will be covered in depth later on. Stepper motors are not perfect, there are always some little inaccuracies. ORIENTAL MOTOR's standard stepper motors have an accuracy of ± 3 arc minutes (0.05°). The remarkable feature of steps motors, though, is that this error does not accumulate from step to step. When a standard stepper motor travels one step it will go 1.8° ± 0.05°. If the same motor travels one million steps, it will travel 1,800,000° ± 0.05°. The error does not accumulate.
Stepper motors can respond and accelerate quickly. They have low rotor inertia that can get up to speed quickly. For this reason stepper motors are ideal for short, quick moves.
