• Affordable
Benefits
• Eliminates
mechanical and
electrical noise
The NanoMuscle 70 Gram High
Speed/High Efficiency Linear Actuator
contracts when activated and requires
a return force, such as a spring, to bring
the actuator back to its initial configuration. In its extended configuration,
the actuator is prepared to contract
again. The NM70 offers low power
consumption, and has a cycle life of well
over 1,000,000 repetitions. All NanoMuscle Motors are available in Economy Grade or Commercial
Grade versions. The Economy Grade version is designed for applications with less stringent cycle life
and environmental tolerances.
• Affordable
for high volume
makers of consumer devices
• Compatible
with complex
as well as simple external
systems
• Reduces
overall system
cost and time to market
• Allows
seamless integration
with a digital system
for use with portable
consumer devices

Time vs Temperature
Depending on the application,
the cycle time of the Actuator
will vary. The graph illustrates
the behavior of the Actuator in
three different applications with
optimum applied voltage. In
a number of applications, the
actuator can cycle faster or at
higher temperatures than indicated. Please contact NanoMuscle
for more information.

CYCLE TIME IN MILLISECONDS
As the Motor cycles continuously,
the cycle time increases until the
unit reaches thermal equilibrium.
The thermal equilibrium point
varies with the ambient temperature and application.
