Electric Linear Cylinders remain in high demand due to applications in window automation, valve operation, and solar panel operation
There are different types of electric
linear cylinders including rotary cylinders, screw threads, ball & rod,
ball & cone, piston, and others. They are designed for applications having
high force to weight ratio, high speed, low energy consumption, and for
applications requiring precision and functionality. Application designs are
provided by leading companies and are used in various industries such as
aerospace, power generation, petroleum, chemicals, transportation, metallurgy,
pharmaceuticals, watercraft, and others. Some examples of application areas
include cranes, wind turbines, marine applications, automotive applications,
steam turbines, power generation, lubricants, lubrication oils, and others.
They have an advantage over
traditional piston and gear-based motor systems that makes them highly usable
in high force to weight ratio applications. There are two main categories of
high-efficiency electric
linear cylinders, namely, open-loop control and closed-loop control.
Closed-loop systems use an active control approach for controlling the electric
force produced by the motor. These types of closed-loop systems include
gyro-statically controlled, self-oscillation, rotary vane guided, and linear
electric motors. Open-loop systems involve no control mechanisms; the system is
self-controlled.
This type of system produces low
energy and has high-efficiency characteristics, which make them ideal for
applications requiring torque and high force to weight ratios. The benefits of
using electrical flex tubing are wide-ranging. First of all, flex tubing
provides an economical means for storing electrical flex lines and transmitting
power from them to a destination. This allows the industry to increase its
capacity at a much lower cost than would otherwise be possible. In addition,
the construction of electrical flex tubes requires less material than would
otherwise be required. Finally, the ease with which electrical flex tube
systems can be installed provides a significant cost-cutting benefit to many
industries. Recently, in January 2021, LINAK launched the world’s first
electric linear actuator with IO-Link.
