2.1.2 Precautions for Storage

WARNING
1. Correctly store the direct-drive motor in the package to transport and store.
-> As the secondary side has permanent magnets in it, and the magnetic attraction force is generated between magnetic
material as iron, unexpected accidents or failures may occur if the secondary side is left unattended.
2. During transportation and storage, draw people's attention by applying a notice saying "Strong magnet-Handle with care"
to the package or storage shelf.
CAUTION
1. Do not arrange the product, or do not give a shock.
2. Do not get on top of or place heavy objects on the product.
3. When suspending the product with lifting sling, etc, do not give a shock or stress to the mold.
4. If the product has been stored for a long time, please contact your local service center or service station.
<How to suspend the product>
(1) Primary side stator
Before you suspend the primary side stator alone, attach eye bolts, etc. to the fixing screws on a surface end.
Please ensure that the wires put no stress on the mold, connector or cooling vent when suspending the product. In
addition, please be careful that no stress is applied to the lead wire when you use lead-out type.
When suspending the product, support it with at least 3 screws.
(2) Secondary side rotor
Before you suspend the secondary side, attach the eye bolts, etc. to the fixing screws.
In order to avoid any risks posed by the magnetic attraction force, the rotary axis must be in the vertical direction,
and support it at 3 or more points to keep its posture.
<Dust and drip proof structure>
Even if the coil end of the primary side stator has mold structure, it cannot guarantee full dust and drip proof. So please
make sure to construct your machine structure to be able to avoid chips, water, oil, cutting fluid, etc. from entering in the
motor.
<Cooling>
Construct the liquid-cooling (oil cooling) structure around the primary side stator according to your conditions, for
example, put a cooling jacket around the primary side stator.
