Motor - Panasonic MINAS A6 Series Operating Instructions Manual

Motor

Oil/Water Protection
1) Don't submerge the motor cable to water or oil.
2) Install the motor with the cable outlet facing downward.
3) Avoid a place where the motor is always subject-
ed to oil or water.
4) Use the motor with an oil seal when used with the
gear reducer, so that the oil may not enter to the
motor through shaft.
Stress to Cables
1) Avoid a stress application to the cable outlet and connecting portion by bending or self-
weight.
2) Especially in an application where the motor itself travels, fix the junction cable into the
bearer so that the stress by bending can be minimized.
3) Take the cable bending radius as large as possible. (When you use our optional cable,
Minimum R20 mm)
Permissible Load to Output Shaft
1) Design the mechanical system so that the applied radial load and/or thrust load to the
motor shaft at installation and at normal operation can meet the permissible value
specified to each model.
2) Pay an extra attention when you use a rigid coupling. (Excess bending load may dam-
age the shaft or deteriorate the bearing life.)
3) Use a flexible coupling with high stiffness designed exclusively for servo application in
order to make a radial thrust caused by micro misalignment smaller than the permis-
sible value.
Note
For permissible load of each model, refer to P.1-26, "Permissible Load at Output Shaft".
Notes on Installation
1) Do not apply direct impact to the shaft by hammer
while attaching/detaching a coupling to and from
the motor shaft.
(Or it may damage the encoder mounted on the
other side of the shaft.)
2) Make a full alignment. (incomplete alignment may
cause vibration and damage the bearing.)
3) If the motor shaft is not electrically grounded, it may cause electrolytic corrosion to the
bearing depending on the condition of the machine and its mounting environment, and
may result in the bearing noise. Check and verification by customer is required.
