Intro12
If sufficient rigidity cannot be attained, machine
resonance is suppressed to some degree by
installing dummy inertia as close to the actuator as
possible.
Examples of adding dummy inertia are shown below.
When extending the output shaft, the following
dimensions apply as a guide to the extended
shaft's diameter:
AX2006T, AX4009T, AX2012T, AX2018T, AX□022T,
AX□045T:Φ60mm and over, AX□075T, AX□150T,
AX1210T, AX4300T:Φ90mm and over, AX4500T:
Φ150mm and over.
As a reference, dummy inertia is [load inertia] x (0.2
to 1). [Fig.]
[Fig.] Example 1. for dummy inertia installation
Dummy inertia
When coupling with belts, gears or spline or when
joining with a key, dummy inertia should be [load
inertia] x (0.5 to 2).
If speed changes with belts or gears, use load
inertia as the actuator output shaft conversion
value, and install dummy inertia on the actuator.
[fig.4] [fig.5].
Note: Install dummy inertia as large as possible
within the actuator's capacity. (Use steel
with a large specific gravity).

Select gears with as large
diameters as possible.
Design & Selection
CAUTION
Do not place the actuator where it may contact strong
magnetic field.
Do not pass cables with high voltage through the
central hollow hole.
It may lead to malfunctioning, lower performance and
damage.
Use of surge protector is recommended when there
is a risk of damage caused by lightning surge.
