Hyosung’s explosion-proof motor is a special self-protective motor which does not ignite due to an external explosion in highly-explosive areas and endures explosion pressures that occur from the inside of its container.

Ex d
The container endures internal explosion pressure when explosive gas explodes or steam causes a large pressure increase. In addition, the motor is structured to protect from external explosive gas or steam that may enter through the joints or openings.
Ex p
The protective gases’ pressure is maintained at a higher level than the external environment to create an explosion-proof structure that protects the motor from external influence.
Ex e
This motor has a mechanically and electrically enhanced safety structure against temperature increases for preventing an electrical spark and arc, which can act as an igniter for the explosive gas or steam in operation.


- International explosion-proof certificates (UL, ATEX, IEC, KR, etc.)
- Solid structure for enduring an internal explosion
- High safety required in petrochemistry plants
