Enjoy the Benefits of Improved Efficiency and Green Automation with IAI’s Energy Saving Electric Actuators!

Robo Cylinders Green Alternative

We are currently facing the declining health of our earth. What can businesses do to improve our relationship with nature?  Reducing energy usage reduces harmful emissions and encourages us to find more environmentally friendly alternatives.

As energy usage increases worldwide and emissions from the production of energy also multiply, we are encouraged to be conscious of energy use and raise efforts to conserve energy.  Energy is something we all use and rely on, and it is an essential aspect in business.
It is also a given that minimizing energy waste and maximizing efficiency leads to higher profits.

Energy is not a fixed cost, but rather a variable cost and there are many ways to improve energy efficiency such as turning off or dimming the lights when not needed, setting computers to hibernate when not in use, changing to more energy efficient light bulbs and introducing energy efficient strategies in automation.  Using energy in an efficient manner will cut running costs and benefit the environment and as a result, can significantly boost the image of a business in the public eye.  With this said, it is clear and essential that we see the convergence of environmental and business needs are indeed in sync.
Our vendor partners at IAI also see this, and are working hard to build energy efficient products so both businesses and our environment can benefit each and every day.  Make Green Automation a part of your business today.

Functions Added To Our Electric Actuators to Enhance Energy Savings

Full Servo Control Mode
In this mode, current of the pulse motor installed in the RCP2 series is reduced to 1/2 to 1/4 in standstill state. It provides an effective way to suppress power consumption when the motor remains in standstill for a long time at standby position.

Automatic Servo-Off Mode
Once positioning is completed, the servo will turn off automatically after a specified time. Since holding current does not flow while the servo is off, power consumption can be reduced. (External force must not be applied while the servo is off.)

Lower Running Costs by 1/3 and up to 1/10th of Air Cylinders with IAI Electric Actuators!Green Graph

With air cylinders, a compressor is operated with electricity to generate compressed air, and generated air is supplied though a line to the air cylinder where it is then converted to linear-motion force. This mechanism is subject to significant energy loss. With IAI Electric Actuators, revolutions of electric motors are mechanically converted to linear-motion force, which minimizes energy loss. The running cost (energy cost) of IAI Electric Actuators are 1/3 to 1/10th the cost of an air cylinder (based on IAI’s internal test)

The Benefits of a Long Maintenance-Free Period

AQ SealsThe AQ seal is a lubrication unit using a lubrication member made of resin-solidified lubricating oil. AQ seals supply lubricating oil as they are pressed against the surface of the guide and ball screw (steel-ball rolling surface). This, combined with the lubrication effect of grease, ensures a long maintenance-free period.

Minimize the number of cumbersome greasing operations required. (When used with grease, the actuator will remain maintenance free for 5,000 km of traveled distance or three years.

  • Effective in locations where greasing is difficult due to the structure of the system.
  • Environmentally friendly, since no extra grease is needed.

Cost Savings GraphBelow is a sample comparison of electricity cost between an air cylinder application and a ROBO Cylinder application. In this example, the air cylinder and ROBO Cylinder are assumed to have the same ratings and carry out the same operation.

Sample Comparison of Electricity Costs (Annual Running Cost)
