•
When you lead an object through the hollow hole, make sure to allow for a clearance of
1mm or more on all sides so the object and the internal surface of the hollow hole are not
in contact. Never press an object into the hollow hole or apply force to it. The precision
and functions of the motor may be impaired, causing failure.
•
For the DR motors, the load mounting surface on the upper surface and the stator at the
bottom surface are coated to prevent rust. When installing the product, wipe away the
coating completely using organic solvent (e.g. thinner, hydrocarbon solvent). If any
coating remains, the precision and functions of the motor may be impaired. Prevent
areas other than the load mounting surface and the stator, such as cables and internal
parts of the motor, from being subjected to the solvent and the left-over coating.
•
Be careful that the load mounting and motor mounting screws do not reach or exceed the
allowable screw depth length on the motor. Depending on the model used, the
functionality of the motor may be impaired and failures may occur if the screws reach or
exceed the maximum depth of the screw hole.
•
When connecting the motor and load, make sure to align the centers of the rotating parts
sufficiently and mount the load with a precision of 0.01mm or less. If the centering
precision is insufficient, abnormal noise and vibration may be generated and the bearing
inside the motor may be damaged.
