Horizontal (IM3001)

Vertical, motor suspended from the machine (IM 3011)With the IM 3011 type of construction and mounting arrangement (vertical, motor suspended from the machine), there is a risk of production fluids or oils penetrating the motor on the flange side. Motors or motor-gearbox combinations that should be used with this mounting arrangement must therefore have at least IP65 protection on the flange side.

WaterWater must be clean and demineralized. For corrosion and germ protection, sufficient additives must be added according to the recommendation of the additive manufacturer. Information as to whether these additives result in reduced heat capacity of the coolant must be requested from the additive manufacturer and taken into account during motor operation.
