It is useful to examine the principal characteristics of stepper motors and
evaluate their advantages
The basic advantage of a stepper motor is that it can operate within
an open loop, that is to say that in normal operating conditions, for n
impulses one obtains n steps.
Stepper motors are found in numerous applications such as :
photocopiers, typewriters, bank printers, computer peripherals, x-y
plotters, instrumentation, medical pumps, drip feeders, vending machines,
gaming machines, automobiles, heating and ventilation and process
control.
The operation of a stepper motor requires the presence of the following
elements :
■
■
■
➜ The variable reluctance stepper motor
This type of motor functions according to the Law of maximum flux.
Constitution :
■
■
➜ The permanent magnet stepper motor

Characteristics
No brushes
Open loop operation
Several step angles
available
Direct motor drive from a
digital signal
Principles of stepper motors
A stator with teeth
A rotor with teeth
A stator with teeth
A magnetised rotor
A control unit ( a micro-processor for example) which supplies impulses
the frequency of which is proportional to the speed of the motor. This
applies equally to both directions of rotation;
A sequencer which will direct the impulses to the various motor coils.
A power supply.
