Variable Frequency Drive Systems and Controls
- Do you have ac motors in your facility?
- Do these motors need a variable output?
- Do you use mechanical means to vary the output?
If you anwsered yes to these questions, you need to install variable frequency drives on these ac motors.
If you are not using VFD’s you are wasting energy and throwing money out the window.
In the United States 50% of the total electrical energy generated is consumed by rotating equipment. 65% of this total is consumed by centrifugal or flow related applications such as fans, blowers, compressors, and pumps according to current estimates. Variable speed drive technology offers a cost-effective method to match driver speed to load demands and represents a state-of-the-art opportunity to reduce operating costs and improve overall productivity.
Joliet Technologies is an OEM that custom packages, integrates and engineers AC Variable Frequency Drives (VFD), DC Variable Speed Drives (VSD) and AC Drive Controllers. Our drive systems integrate top of the line manufacturers, like ABB, Emerson (Control Techniques & Saftronics / Fincor), Siemens and WEG to name a few. Our added value custom drive packages are built to your specifications for your application.
You can divide the world of electronic motor drives into two categories: AC and DC, a motor drive controls the speed, torque, direction and resulting horsepower of a motor. AC drives control AC induction motors. DC drives typically controls a shunt wound DC motor, which has separate armature and field circuits.
Motor drives are also known as DC Drives, AC Drives, SCR Drives (Silicon Controlled Rectifier Drive), Variable Frequency Drives, Variable Speed Drives, Adjustable Speed Drives, Electric Motor Drives, Electronic Motor Drives, AC Motor Controllers, AC Inverters, Pulse Width Modulation (PWM) Drives and a few other names.
Which Drive is Right for your Application?
The AC Variable Frequency Drive market is huge, due to the great advances in highly reliable AC power electronics and high power microprocessors. The Flux Vector AC Drive for example, can compete on an application basis that DC Drives would in earlier years be required.
Even though AC Variable Frequency Drives are readily replacing DC Drives and motors, there is still a large base of DC equipment that has to be supported by experienced technicians. Joliet Technologies believes that by not abandoning the DC market we can better serve our customer base demands. For example, older machines with multiple exciting DC Analog drives and motors may be a great candidate for retrofitting newer digital DC drive equipment. Saving cost and down time.
If your needs are much simpler and speed control is not part of the work scope. Joliet Technologies can provide Custom AC Drive Controllers consisting of contactors, starters, relays, pushbuttons and PLCs. Our engineers can provide all PLC and Peripheral Programming needs. Panels can be designed by another OEM or we can help with engineering to specifications provided.
