AC Variable Speed Drives

What is a Variable Speed Drive?

A variable speed drive, or inverter, works by changing the speed of motor by varying the voltage supplied to it.  Variable speed drives consist of either AC (alternating current) or DC (direct current) drives.

What is an AC variable speed drive and why should I use one? 

An AC variable speed drive consisits of four key components; the user interface, the AC motor, the electrical supply and the process interface.  The intuitive user interface enables you to obtain process information, making it simple to integrate with other process control systems or even override other process control systems. 

By utilising an AC variable speed drive, you can benefit from the following features; 
1.  Precise speed control and controlled currents; helping to extend your motors lifespan. 
2.  By implementing a variable speed drive and controlled motor stopping, the motor in your application will benefit from a lower level of wear and tear. 
3.  The components of an AC variable speed drive do not require regular maintainence like other drives; resulting in lower maintainance costs.

Variable speed drives applications:

Variable speed drives are suitable for a number of applications including; pumps, compressors, conveyor belts, lathes, mills, food processing production lines and many, many more...
1. Fans - A variable speed drive is a much more energy efficient way of reducing fan speed, than a dampner. 
2. Pumps - Using throttle control for pumping applications results in poor energy efficiency.  By using a variable speed drive the pump is run at the most appropriate design speed for improved energy efficiency. 
3. Pressure Control - A variable speed drive will adjust the pump speed based on feedback signals to maintain a constant pressure through changes in flow.
