General

Stepper motors are motors which, like most

electric motors, consist of a fixed stator and a

moveable rotor. The rotary motion is not

continuous, rather the rotor turns in steps, a

certain angle at a time, for example 90°.

Design

The illustration shows the basic design of a
stepper motor with 1 pole pair and 2 phases.

The stator is made of magnetically soft iron

and holds the windings. Opposite windings

belong together and form a phase (in this

case, a and b). The rotor consists of a

permanent magnet. In the illustration the rotor

has 1 pole pair.

Function

The rotor is turned by applying current

through phase aor b (see illustration). The

magnetism in the stator changes according to

the polarization (I) of the phases.

The rotor will turn so that its south pole (S) is at the north pole (N) of

the stator and its north pole (N) is at the south pole (S) of the stator.

The illustration shows a full rotation of the rotor. The rotor moves in

steps of 90° from positions 1 through 4 and back to its starting

position.

Unlike normal electric motors, the motor can stop in each of these

positions with a certain holding torque. This type of motor is therefore
particularly suitable for use as a servomotor for exact positioning.
The size of the steps can be reduced considerably by increasing the

number of pole pairs and phases.

Theoretically, it is even possible to make the steps infinitely small

with just a few poles and phases by using complicated electronic

phase control (sine-cosine control).

Stepper motors (with sine-cosine control) are used, for example, for

pointing instruments in the instrument cluster (A1).
