ENIGIN’S INTELLIGENT MOTOR ENERGY CONTROLLERS (iMEC)
How does iMEC work?
AC induction motors consume more than half of all the worlds’
energy! Unfortunately, motors lack the intelligence to address
three key problems that lead to massive energy wastage,
unnecessary carbon emissions and undue wear and tear:
1) Fixed speed motor driven applications like escalators cannot
intelligently adjust their torque output to match load changes
leading to excess energy consumption.
2) Motors that drive applications like pumps & fans cannot
intelligently adjust their speed to match load changes and as such
consume more power than they need.
3) When starting, a motor develops more torque than is
required at full speed. This high inrush of current can lead to
mechanical breakdown and peak demand penalties. To avoid the
problems associated with starting, motors are often left running
continuously even when they are not being used which leads to
huge energy waste.
The iMEC solution effortlessly addresses all of these problems
by introducing intelligence to your existing systems:
1) iMEC can be applied to fixed speed applications and will
dynamically adjust the torque output to meet load requirement
without altering the speed (see fig. 1). This leads to substantial
savings and is ideal for applications like escalators and many others
which run at no/low load for long periods of time. In the right
applications, payback is typically under two years!
2) iMEC can be specified to intelligently adjust the speed of
your motors to match their variable loading so your motors only
consume the power they need. This is a vast improvement over
traditional control methods (see fig. 2). A mere 20% reduction in
speed can lead to energy savings of up to 50%!
3) iMEC provides a smooth, step-less acceleration (soft start) of
your motors (see fig. 3). This dramatically reduces wear & tear on
your system and helps you to avoid peak demand penalties. With
a controlled start in place your motors can now be switched off
without the fears of re-starting and iMEC can be programmed to
perform this function automatically. Auto Switch Off delivers 100%
energy savings!
Use iMEC to get your motors under control – it’s a great way to cut your costs, boost your profits and ‘do your bit’ in the fight against climate change

Note the difference between a capacitor-based power factor correction system and a motor controller:
Capacitors are fixed and cannot compensate for varying degrees of inductance.
Motor controllers dynamically adjust response using a microprocessor-based system.
We will evaluate your facility for free and advise which is the best motor control solution for your needs. We can supply you with Enigin fixed-speed motor controllers, torque controllers, soft-starters, and a multitude of other solutions.
Why buy a one-size fits all solution when you can get customized energy saving equipment?

I am a homeowner with an irrigation well. I use a 240vac 1hp submersible pump for 10 hrs/day/ for 6mo/yr. Irrigation pressure varries from 30psi @ 15gpm to 60psi @ 10gpm.
Will this technology be cost efficoent to apply in this situation?

While it would be helpful to know how much time is spent pumping at which rate, and how many start / stops occur per day, if you don’t know, we can provide a data logger for as little as $ 100.00. The data will upload into your computer as an Excel file, which you can email to us.
It would also be useful to know your electricity rate, but for this purpose we will use Baltimore Gas & Electric’s retail rate of 15 cents per kWH.
However, I would imagine that your pump is more than 50% loaded, and would not achieve great savings. The soft start controller can save SOME money if your pump has many start / stop cycles. More importantly, the soft starter can increase lifespan of your equipment by avoiding sudden impulses to your system, which can be damaging not only to the motor, but also to your piping.
Personally, I use two of these controllers at home: On my heat pump compressor and on the air handler fan. Nevertheless, I have not done an analysis of savings from these two soft starting controllers.

I was searching for Blogs about capacitor 25 kvar and found this site. I am interested in your content and appreciate sites like this.

Dear Anonymous,
I noticed that you link back to a KVAR sales site, and I have decided to allow your comment and your link.
I just hope you do a fair analysis of reactive power for your customers and properly size the capacitor bank to precisely offset the inductive reactance you are trying to correct. Getting close to power factor of 1 is the goal.
Going too far by creating too much capacitative reactance will drop the power factor lower in the other direction. Tipping the scale the other way is just as bad as the problem you are trying to correct. More capacitors does not equal better solution.
Therefore, any “off the shelf” or “one size fits all” solution you sell can be misleading.
The same warning goes for motor controllers: One size does not fit all, though there is no danger from “over-sizing” the motor controller. However, a huge danger exists from under-sizing it.
One must also consider where a variable speed controller is a better solution than a torque controller.
In considering whether to apply a soft starter or torque controller, you should also consider the number of start / stops per day, and the percentage loading. The optimizing function of Enigin’s torque controllers (iMEC) make them a good selection for refrigerator, freezer, chiller and air conditioner compressors, as well as some fan applications and conveyer belts.
Motor controllers also save in maintenance costs. Ever hear that “slamming” sound when your motor turns on? Your application might benefit from soft starting using the Enigin iMEC torque controller.
Same principle as accelerating your automobile. Slamming the car into first gear at the green light wastes energy and will wear out your car’s engine.
Slow it down and save energy and protect your equipment: Consider an Enigin iMEC motor controller.
