摘要:
The invention relates to an electric motor (10) and to a method for producing said electric motor, especially for adjusting mobile parts in a motor vehicle. Said electric motor comprises a collector (36), arranged on an armature (38) and electrically contacted via hammer brushes (12). The armature (38) is surrounded by a lower housing part (32) and an upper housing part (34) which can be assembled in a radial direction (50) in relation to the armature (38). The hammer brushes (12) comprise one fastening element (26) each which engages directly in a seat (30) of the lower or upper housing part (32, 34).
摘要:
In a method of monitoring the condition of soiling and/or calcification of heat exchangers in heating installations, subsequent operational data of temperature and pump speed are collected in turns during the operation and compared with the initial operational data of temperature and pump speed collected in an initial condition, for instance when an installation is put into service initially. When an admissible deviation of the subsequent operational data from the initial operational data is exceeded, which is as a rule to be attributed to the soiling and/or calcification of the heat exchanger, a corresponding malfunction signal is emitted or the heating installation is switched off. In accordance with the method, a conventional heating installation is provided with a monitoring device, by means of which the soiling and/or calcification of the heat exchanger is automatically checked in turns.
