Page 3: General Information
1 General information This manual concerns normal three phase induction motors with an output varying from small to middle size; they are externally cooled, totally enclosed, supplied in a cast iron or aluminium frame and provided with ball bearings or roller bearings, lubricated with grease. -
Page 4: Indirect Coupling
4.2 Indirect coupling 4.2.1 Flat belt or V-belt Mount the motor on slide rails in order to adjust belt tension. The belt pulley has to be fitted hard up the shoulder of the shaft. The pulley center line should be within the shaft center line. -

only suited for one direction of rotation, it is indicated with an arrow on the motor fan cowl. Connecting cables must comply with the IEC regulations. Line fuses only protect the cables in case of short–circuiting and do not constitute a safeguard against the overheating of the winding caused by overload. -
Page 6: Putting Into Service
If only one voltage is indicated on the nameplate together with the delta sign, the motor can be switched on directly at the indicated voltage or with a star/delta starter. Pole change motors (for two or more speeds) are connected according to a diagram sent together with the motor. -
Page 7: Wear & Vibrations
7.3 Wear & vibrations To prevent abnormal wear & vibration, one should: a. Take care that the tension of the belt or the chain is not too high; b. Check whether the mounting of directly coupled machines is correct; c. Check whether the foundation bolts to fasten the motor and the slide rails are tightly fixed. -
