Technical data

Stator/Rotor core
Stator/Rotor core
Laminated and enamel-insulated on both sides to minimise eddycurrent losses.
The stator winding is made in flat copper or round copper wire depending on the machine size.
The completely wound stator pack with housing is thereby impregnated in an epoxy-resin VPI.
The subsequent heat treatment hardens the resin.
Rotor
Rotor
Short circuit rotor type.
Depending on machine size, the rotor construction is usually a solid shaft type.
The rotor winding can be either a pressure die cast aluminum or a copper bar construction.
Bearing
Bearing
General data
Motors are normally fitted with single-row deep groove ball bearings.
  • Up to 132 frame size bearings are lubricated for life.
  • From 160 frame size and above motors are supplied with regreasable bearings and greasing nipples on both ends.
The motor bearings are designed according to the principle that the locating bearings are on the D end side and the floating bearings on the ND end side.
Bearings are first greased in the factory with lithium base grease.
The used grease is removed through a valve locked in the outer bearing cover. Sleeve bearings available as an option.
Impregnation system
Impregnation system
Stator is VPI treated with an unsaturated polyester amide resin which is polymerisation in an oven.
Insulation system
Insulation system
Stator: F class insulated with a synthetic enamel.
(H class insulation available on request)
Protective treatments
Protective treatments
Specific Oil&gas treatment.
Vibrations
Vibrations
Mechanical vibrations correspond to the limits specified in EN 60034-14 and are certified by the test room.
Rating plate
Rating plate
Stainless steel, thickness 0,5 mm.
