IDS are ABB Inverter specialists. We specify, install, commission, repair, service and hire variable speed drives.
The History There has always been a need for variable speed motors; dc motors were the first cheap, simple variable speed motors. They superseded NS motors, Schrage motors and eddy current drives with variator gearboxes trying to inefficiently compete mechanically. The dc motor offered a compact, relatively efficient reliable motor with good speed control and […]
In the this article we describe how VSDs are used for motor control to save energy for commercial and industrial high energy users. An inverter, also known as a Variable Speed Drive (VSD), is electronic equipment that attaches to a motor to alter and control its speed through a control mechanism, such as temperature […]
CONTROLLING THE THICKNESS OF SLUDGE AT SOURCE Abstract Primary and co-settled sludges are commonly removed from settlement tanks using timed, pumped, auto-desludge systems that are neither sensitive to the variable flux of settleable influent material nor sense the thickness of the sludge removed, resulting in thin sludge being produced which requires significant thickening before digestion […]
IP ratings (Ingress Protection ratings) will guide you and help to define if an electronic device is suitable for the environmental conditions it will be sited in, by describing how well protected it is against intrusion from foreign bodies. Our Inverter IP Ratings infographic below will guide you when choosing the right inverter for your […]
Rarely are there so many names and terms used to describe the same thing. Whilst compiling a new blog for our website, we decided it was about time we attempted clarification, by devising a glossary of terms for inverters. But first we need to understand the nature of the beast, so to speak! What is […]
In your factory or offices you will find electric motors all over the place. They drive the air compressor that supply your factory’s air and power the fans that blow the air in your offices from your air conditioning. They are the thing that you switch on in the morning and off in the evening […]
If an AHU (air handling unit) or associated pumps do not have inverters fitted, then the chances are the air and water flow created by the motors are controlled by the partial opening and closing of dampers in the ducting, or valves where water is moved around. To gain HVAC flow control this is sometimes done manually […]
An Inverter can be compared to a dimmer switch for lighting. Usually your lights are either on or they are off, when you add a dimmer switch you are able to choose your level of lighting. The same principal applies with Inverters and industrial motors. As Pirelli say: ‘Power is nothing without control!’ What is an […]
