5 System overview
General information on stepping motor systems
Description
Stepping motors are a special type of synchronous motor triggered through electriĆ
cal pulses from a required control unit. Here, a pulse always corresponds to the
same rotational angle. This permits positioning without acknowledgement.
Due to their "digital" rotation, stepping motors are used as switch mechanisms
and in positioning technology. It should be noted that the control system does not
receive any kind of acknowledgement that the motor has, in fact, performed its
step.
