4.1.3.
Storage
Before being mounted, the torque motor has to be stored in a dry place, without rapid
or important temperature variations in order to avoid condensation.
During storage, the ambient temperature must be kept between -20 and +60°C.
If the torque motor has to be stored for a long time, verify that the shaft end, feet and
the flange are coated with corrosion proof product.
After a long storage duration (more than 3 month), run the motor at low speed in both
directions, in order to blend the bearing grease spreading.
The motor is delivered with caps for the water inlet and outlet to protect the cooling
circuit. Keep them on place until the motor commissioning.
4.2. Installation
4.2.1.
Mounting
Foundation must be even, sufficiently rigid and shall be dimensioned in order to avoid
vibrations due to resonance. Before bolting the motor’s feet, the foundation surface
must be cleaned and checked in order to detect any excessive height difference
between the foot locations. The variation from one foot to any other shall not exceed
0,1 mm. In any case we recommend using shims to compensate small irregularities.
Caution: The user bears the entire responsibility for the preparation of
the foundation.
The table below gives the average tightening torques required regarding the fixing
screw diameter. These values are valid for both motor’s feet and flange bolting.
