4.1.3. Storage
Before being mounted, the 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.
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, the foundation surface must be
cleaned and checked in order to detect any excessive height difference between the motor
locations. The surface variation shall not exceed 0,1 mm. In all cases, we recommend using
shims in order to compensate small irregularities.
Caution: The user bears the entire responsibility for the preparation of the
foundation.
4.2.2. Torque value for the screws
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.
