Damel applies pyrolysis process in electrical furnaces made by Maxei for removal of binding agents and inflammable insulation materials from stator cores of the motors on overhaul. For determination of pyrolisis effect on magnetic circuit durability, particularly on possible increase of power losses a single stator core was exposed to repeated pyrolysis and impregnation process. Pyrolysis process was performed at temperature of 290÷380°C during 16 hrs. Total time of keeping the charge in furnace was of 32 hours. For measurement of power losses the stator core was provided with both-magnetizing (current) and measuring (voltage) windings. The applied method enabled measurement of power losses in stator core keeper only, and did not comprise power losses at the stator taps. Magnetizing winding was indirectly connected in series with current coil of wattmeter through measuring transformer meanwhile measuring (voltage) winding was linked with voltage coil of the same wattmeter. Power losses were measured always at the same induction in the stator core keeper amounting to 1,5 T. Upon completing the third pyrolysis and impregnation cycle power losses were lower than those observed in a new core. After the fifth pyrolysis cycle had been completed, further impregnation did not reduce power losses anymore, and such losses were higher by 4% in compare to those observed in a new core. Upon completion of next 5 pyrolysis cycle power losses in the core exceeded those observed in new core by 12 %.
