When to Use a Stepper Motor
A stepper motor can be a good choice whenever controlled movement is required. They can be used to advantage in applications where you need to control rotation angle, speed, position and synchronism. Because of the inherent advantages listed previously, stepper motors have found their place in many different applications. Some of these include printers, plotters, highend office equipment, hard disk
drives, medical equipment, fax machines, automotive and many more.

 

The Rotating Magnetic Field
When a phase winding of a stepper motor is energized with current a magnetic flux is developed in the
stator. The direction of this flux is determined by the “Right Hand Rule” which states: “If the coil is grasped in the right hand with the fingers pointing in the direction of the current in the winding (the thumb is extended at a 90° angle to the fingers), then the thumb will point in the direction of the magnetic field.”

 

Figure 5 shows the magnetic flux path developed when phase B is energized with winding current in the
direction shown. The rotor then aligns itself so that the flux opposition is minimized. In this case the motor
would rotate clockwise so that its south pole aligns with the north pole of the stator B at position 2 and its
north pole aligns with the south pole of stator B at position 6. To get the motor to rotate we can now see that
we must provide a sequence of energizing the stator windings in such a fashion that provides a rotating
magnetic flux field which the rotor follows due to magnetic attraction.

 

 

 

The magnetic field generated in the stator induces an EMF in the rotor bars. In turn, a current is produced in the rotor bars and shorting ring and another magnetic field is induced in the rotor with an opposite polarity of that in the stator. The magnetic field, revolving in the stator, will then produces the torque which will “pull” on the field in the rotor and establish rotor rotation.

 

In the design of the induction motor, operational characteristics can be determined through a series of calculations. Performing these calculations can help the engineer provide a motor that is best suited to a particular application. This paper will demonstrate their application.
