INDUCTION MOTOR WHICH IS EXPLOSION-SAFE

摘要

FIELD: alternating current electric motors. SUBSTANCE: device has housing 1, bed 3 with adjacent stator 2 with winding and bearing housings 4. Fan 7 is mounted on shaft 5 of rotor 6 between one bearing housing 4 and housing 1. Inner space of electric motor is separated into two parts by means of two rigid diaphragms 8. One side of each diaphragm 8 is connected to stator 2 in vicinity of winding, another side of diaphragm 8 is connected to bed 3 in vicinity of its connection to bearing housing 4. Stator 2 has axial channels 9 between connection points of diaphragms 8 and bed 3. Radial holes 10 are provided in both sides of bed 3 between stator 2 and diaphragms 8. Deviation caps are provided over holes 10. EFFECT: increased functional capabilities. 1 dwg
