Abstract: A protection system for an electrical machine includes a first connecting line for connecting an internal space of the electric machine to an external space surrounding the electrical machine, a valve, and a filter which is impermeable to dust. The valve and the first connecting line are configured to render the first connecting line impassable when the valve is closed, and to enable a first gaseous medium to enter the internal space from the external space when the valve is open. The filter is configured to filter the first gaseous medium that enters the internal space from the external space through the first connecting line.

Abstract: An electric machine includes a stator, a rotor interacting magnetically with the stator, a housing surrounding the stator and rotor, and a hollow shaft provided for arrangement of the rotor and mounted on the housing. A radial fan is mounted rotationally fixed on the hollow shaft on the ventilation side. A section of a fan blade of the radial fan extends axially away from the housing to a greater extent than the hollow shaft. A guide element with radially extending plate is arranged in the hollow shaft, wherein the plate is arranged axially further away from the housing than the end side of the hollow shaft on the ventilation side. An inner coolant flow can thus be delivered from the section of the fan blade out of the hollow shaft through a passage between the end side of the hollow shaft on the ventilation side and the plate radially outwards.

Abstract: The current diverter rings (CDRs), captured CDRs, bearing isolators, and explosion-proof CDRs serve to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One embodiment of the explosion-proof CDR includes a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft may be encompassed by stator and a cap, which cap may be secured directly to the stator or the housing. A conductive assembly may be positioned in a radial channel formed in the stator such that the conductive assembly contacts the shaft to conduct electricity from the shaft to the housing. Another embodiment of an explosion-proof CDR does not require a rotor. The explosion-proof CDR may be configured to define a flame path to achieve various explosion-proof certifications.
