  • Page 28: Component Functions

    Indesit Company COMPONENT FUNCTIONS General Information The power module is made up of a number of smaller individual modules (sections), each one controlling a functional component. The modules are linked together when required to control a particular function or functions. The linking of the individual modules is optional and therefore allows for each module to be switched ON or OFF, this is determined from the data stored or collected by the modules and the results of module comparisons.

  • Page 29: Component Functions

    Indesit Company COMPONENT FUNCTIONS Stepper Motor Characteristics (for the damper and dispenser motors) Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron.
