1. Installation
Connection with Machines
Use a coupling to absorb angle and direction deviations so that the motor shaft load will be less than the rated
allowable axial load.
Otherwise, the bearing life in the motor will be shorter, or the shaft may become damaged.
If you are using a rigid coupling, install it very carefully such that the axial misalignment will be minimal. (Using a
flexible coupling is recommended.)
Countermeasure for Oil and Water
Do not use any cable immersed in water or oil.
Install the motor such that the cable side is facing downward.
Do not use the motor in an environment where it will be constantly subjected to oil or water splash.
In the case that a speed reducer to be connected to a motor will be located over the motor shaft, use an oil-sealed
motor so that no oil from the speed reducer permeates into the motor.
Types of Mounting and OilSeal
SD3 series motors can be mounted in two different ways, horizontally and vertically. Observe the following
precautions for motor installation.
Horizontal Installation
To protect the motor from oil or water, have the cable-pull side downward.
Vertical Installation
If a speed reducer is connected to a motor such that it will be located over the motor shaft, use an oil-sealed
motor so that no oil from the speed reducer permeates into the motor.
Stress to the Cables
Be careful not to apply stress, such as excessive bending or motor weight, to the cable-pull part or its connecting
section.
In motor movable operation, be sure to use a flexible cable.
When placing the cable in a cableveyor, minimize the bending stress to the cable.
Bending radii of the motor power cable must be more than R20 mm.
