Step Motors proceed to provide for robotic functions and automation world-wide. Step motors will probably have their uses multiplied in the long term as the number of applications maximize.
Different stator assemblies are made with a particular number of coils so that you can choose and use the best kind of motor for that particular job. Some common construction methods will have three, four, or five windings.

These are known as as phases. So a motor with four windings is called a four phase motor. The most frequent edition is a four phase motor. The three sorts of step motors are typically variable reluctance, permanent magnet, and hybrid.
Variable reluctance step motor's rotors are typically constructed with smooth iron and electromagnet stator, and have been available in the market the longest.
The stator is crafted from steel with the coils of each winding draped around the steel stampings. The steel stamping has teeth on theme and this differs significantly from design to design.The larger motors with more teeth do not have windings or magnets on the rotor and are different than the hybrid and permanent magnet motors.
The permanent magnet and hybrid motors differ against the variable reluctance motor mostly due to the engineering of the rotor. The rotor is magnetized along the radial axis. Because the motor is commutated electronically, the rotor rotates to follow the flux path. The hybrid variety is a blend of the variable reluctance in addition to permanent magnet styles. The hybrid step motors are made with magnets in the rotors covered with soft iron completely around the rotor.
