Three-phase asynchronous motor with a short circuit rotor. It is designed as a wet running motor with a watertight insulated winding. All motors are rewindable. The motor connection for 6- and 8-inch motors are according to NEMA-standard. The bearings are lubricated by the motor filling. It is a mixture of glycerine and water. Glycerine is biodegradable and secures the anti freeze protection up to -25 °C. If necessary, it can be changed with pure drinking water. Axial down thrusts will be absorbed by the axial thrust bearing with individual tilting pads.
Construction complies with VDE-regulations and the motors are conform to the EC declaration of conformity as defined by machinery directive 2006/42/EEC.
Motors are usable in horizontal and diagonal position depending of the nominal power. Motors are working electrical clock- and anticlockwise.
