Protection system for motor in explosive atmosphere - has two half-sheathings complying with safety requirements and ignition-confining laminae with ventilation passages

摘要

The protection system has two half-sheathings complying with safety regulations and preventing the motor from igniting its surrounds. Internal ventilation carries heat away through the two half-sheatings to the outside. Heat is drawn in and led away through laminar stacks. The stacks comply with the EN 50014 standard and prevent any internal ignition from spreading to the outside. The stack may have any shape suitable for preventing the spread of ignition. The motor's stator casing has holes to allow heat to escape.
