Coffee machine, has electrical drive consisting of stator with coils and rotor with magnetic components, where coils are arranged along adjustment way and are controlled by electronics by traveling magnetic field

摘要

The machine has a functional part i.e. height-adjustable beverage outlet (10), adjusted to frame-fixed parts of the machine by an electrical drive. The electrical drive consists of a stator (1) with coils and a rotor (2) with magnetic components, where the coils are arranged along an adjustment way. The coils are controlled by an electronics (3) by a traveling magnetic field. The stator is fixedly connected with a housing (20). The functional part is guided into a housing-fixed guide (5). The height-adjustable beverage outlet is connected with a beverage supply by a hose (12).
