DMA2 & DM1 Mounting & Maintenance Instructions

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

frame and provided with ball bearings or roller bearings lubricated with grease.

After receipt, remove the package material if any and mind the parts that have been

delivered loose. In the case of unpacked motors, the glands are often put in the terminal

box to protect them against damage.

Check the motor to see whether transport damage has occurred.

You should be able to rotate the shaft easily and smoothly with the hand.

Compare the details on the rating plate with those of the power network and with the

requirements of the motor.

The motor must be fixed on a stable, clean and flat foundation with good fitting

foundation bolts, using washers. Never mount a motor manufactured for a horizontal

mounting on a surface with an angle of inclination of more than 15 degrees without

consulting the supplier in advance.

Foot & flange motors always have to be mounted in such a way that the drain holes, if

any, are situated at the bottom, otherwise you run the risk that moisture has condensed

into the motor and cannot be drained off. To this end you need to remove the drain plugs.

Under no circumstance must the free flow of air be obstructed to the cooling fan or the

motor will overheat. This has also to be borne in mind when you are mounting motors in

enclosed spaces of small size. The ambient temperature must not exceed 40 degrees

centigrade, unless otherwise agreed upon at the time of ordering.

4.1

The motor and driven shafts must be accurately aligned. In case of a flexible coupling, the

manufacturers distance between the parts to be coupled must be adhered to, also the

degree of misalignment must be within the makers tolerance. We do not recommend using

solid couplings.
