Integra Dynamic Motor Controller
Energy Efficient
Due to variable duty cycles, many of your motors probably run at less than 50% of their capacity for much of their duty cycle. It is well known that motors are unintelligent and that in these off-load parts of the duty cycle they consume much more electricity than they actually need.
This excess consumption is not only an unnecessary cost on your energy bill, but it also serves to damage your equipment as the excess energy is released through the windings of the motor in the form of heat, vibration and noise. Integra gives your motors intelligence through monitoring the load on the shaft of the motor for every cycle of the supply. The Integra will then feed your motors the electricity that they require to run efficiently at any point in the duty cycle.
Integra integrates fully with its surroundings, and can even switch your motors off automatically when they are not being used, or use stored energy in certain applications (such as flywheel mechanisms) to reduce your electricity consumption even further.
Integra will quietly work on your behalf to...
- Ensure that your motors only consume the energy that they require
- Switch your motors off automatically when they are not needed
- Significantly reduce your energy bills
- Protect the motors from excess heat and vibration
- Reduce levels of unscheduled breakdowns
Soft Starter
Integra is one of the finest soft-starters in the world with a wide range of adjustable features that allow you to start even the most awkward load with ease. Fully adjustable ramp times from 0-255 seconds give you ultimate flexibility. For high inertia loads Current limit will provide you with a reduced current start. A kick start facility will help you to get things moving on loads with high static friction.
High in-rush current and uncontrolled torque when starting your motors almost certainly causes you problems. This is an unnecessary worry as there is a solution that is well proven and readily available. The advantages of using a soft starter as opposed to, for example direct-on-line or star-delta are now comprehensively documented. The soft start is in effect an electronic clutch. Gradual uptake of power, smooth, step-less acceleration, less stress on you and your valuable equipment. Why make problems for yourself?
Using Integra as a soft-starter will put you back in control by...
- Significantly increasing the life of your contactors & drive train components
- Preventing dips in supply when starting larger motors
- Allowing you to attach more equipment to a single supply
- Allowing you to switch your motors on and off at any time because of reduced start current
- Reducing the worrying threat of peak demand penalties when starting
Controlled Stopping
Pumping applications are particularly vulnerable to damage from hydraulic shock caused by fluid surge. Integra reduces sudden changes in flow by controlling the acceleration torque of the pump, extending the time to produce 100% flow, thus minimising the damaging effects of water hammer.
Using a DOL starter to stop your pump (coast to stop) will cause hydraulic problems because the system head will quickly overcome the motor inertia and then the pump will come to a rapid stop. The fluid, which is in motion and has momentum, must come to a complete stop as well. This uncontrolled stop will cause pressure surges on your pipes and valves - causing damage to the system.
The soft stop feature in Integra will control the deceleration of your pump by accurately controlling motor torque and allowing the head of water to slow the pump, preventing any sudden changes in speed and minimising any surges or hammering in your system.
Alternatively, there are a number of situations where you may need to stop your applications under controlled conditions for safety or operational reasons. An application with high inertia such as a circular saw will require a brake to be applied; this can be an expensive addition to the application. Integra can be configured to reverse the incoming supply and provide controlled braking, bringing the load to a safe stop.
Integra is a highly cost-effective method of tackling all of the above and insuring yourself against the unforeseen mal-effects of uncontrolled stopping.
Through controlled deceleration, Integra Soft Stop...
- Provides an effective solution to minimise water hammer
- Reduces the probability of damage to pipe systems
- Provides safe, cost effective plug braking
