Zusammenfassung: The experience made so far with the new testing and certification concept for frequency-converter-fed motors of the type of protection "increased safety" is extremely promising, and it turned out that a certification for operation on the converter is possible without any problems up to temperature class "T3“. The prerequisite for a safe operation, however, is that the operating parameters of the motor specified in the data sheet are complied with and that the winding is suited for the occurring voltage impulses.
The new testing and certification concept for frequency-converter-fed motors developed at PTB has clearly increased the attractiveness of their use in potentially explosive atmospheres and opens up large energy saving potentials. As coupling of the converter to the motor is now no longer necessary for the type of protection "increased safety", the costs of the motor have been considerably reduced while a flexibility almost identical to that of a "flameproof enclosure" has been achieved.
