Motor

Installation Place
Since the conditions of location affect a lot to the motor life, select a place which meets
the conditions below.
1) Indoors, where the products are not subjected to rain or direct sun beam. The prod-
ucts are not waterproof.
2) Where the products are not subjected to corrosive atmospheres such as hydrogen
sulfide, sulfurous acid, chlorine, ammonia, chloric gas, sulfuric gas, acid, alkaline and
salt and so on, and are free from splash of inflammable gas, grinding oil, oil mist, iron
powder or chips and etc.
3) Where the motor is free from grinding oil, oil mist, iron powder or chips.
4) Well-ventilated and humid and dust-free place, far apart from the heat source such as
a furnace.
5) Easy-to-access place for inspection and cleaning
6) Vibration-free place.
7) Avoid enclosed place. Motor may gets hot in those enclosure and shorten the motor life.

rating
water proof performance is required such as continuous wash-down
operation.
*1 Ambient temperature to be measured at 5cm away from the motor.
*2 Permissible temperature for short duration such as transportation.
How to Install
You can mount the motor either horizontally or vertically as long as you observe the followings.
1) Horizontal mounting
• Mount the motor with cable outlet facing downward for water/oil countermeasure.
2) Vertical mounting
• Use the motor with oil seal (non-standard) when mounting the motor with gear
reducer to prevent the reducer oil/grease from entering to the motor.
3) For mounting dimensions, refer to the technical reference. (DV0P4210)

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 subjected to oil or water.
4) Use the motor with an oil seal when used with the gear re-
ducer, 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 attached cable and
contain the extension junction cable into the bearer so that the stress by bending can
be minimized.
3) Take the cable bending radius as large as possible. (Minimum R20mm)
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
damage 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.
4) For permissible load of each model, refer to the technical reference. (DV0P4210)
Notes on Installation
1) Do not apply direct impact to the shaft by hammer while attaching/detaching a cou-
pling 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 condi-
tion of the machine and its mounting environment, and may
result in the bearing noise. Check and verification by customer
is required.
