How To Get Improved Energy Efficiency with Variable Speed Drive (VSD)?

Variable Speed Drive (VSD):

A variable speed drive's (VSD) primary job is to regulate the amount of power that is sent from the grid to the manufacturing process. Interposed between the power source and the motor is a variable speed drive. The electrical supply powers a drive, which in turn controls the amount of power sent to the motor.

The input power is fed through a rectifier within the drive, which changes the AC current into DC current. Capacitors within the drive are charged by the DC power supply. This procedure is performed to clean up the electrical waveform so that the next process can proceed without interruption. Next, the DC electricity from the capacitors travels into the inverter, where it is converted to AC power for the motor.

As a result, the drive can modify the input voltage and frequency to the motor to meet the needs of the process at hand. This means that you can adjust the speed or torque of your AC motors to meet your specific application's requirements. This is why you can save enormous amounts of money utilising AC drives.

Energy savings aren't the only benefit of using variable speed drives; they also help cut down on waste, noise pollution, and the expense of routine repairs. They are also a fantastic approach to achieving your green objectives.

A variable frequency drive (VFD) is widely popular as AC drives and a variable speed drive (VSD) refers to both AC Drives as well as DC Drives. VFDs vary the speed of an AC motor by adjusting the frequency of the motor. DC motors with VSDs can change their rotational velocity by altering the supply voltage to the motor. Group Nish is an excellent manufacturer as well as supplier of VSD for Chemical Industries in India.

Save Big by using VSD to control motors:

In the industrial sector, electric motors account for over 70% of total electrical energy use. Pumps, fans, compressors, conveyors, and any other machine that relies on rotational force to function rely on motors like these to keep things moving.

It is with these motors that you will be able to cut down on your energy consumption and carbon dioxide emissions or provide your consumers with more environmentally friendly options. Pumps, fans, and compressors are frequently operated at a constant speed, with the destination as well as flow rate controlled by manually opening and closing valves in the pipelines. As an example, establishing a pumping station may require as much as an hour of work by a single person. Travel time to far-flung sites adds to the price of labour. Some facilities have automated the procedure but at the expense of excessive energy usage.

A more eco-friendly option is available. Energy costs are reduced immediately when these applications are run with variable speed drives, and these savings can be leveraged to gain a competitive edge in the market. The use of variable speed drives can provide significant operational as well as cost-saving benefits for any process that employs electric motors. No matter how big or small your operations and processes are, you should seek places where VSDs can be strategically used to reap the benefits of both rapid ROI and sustained competitive advantage.

Using VSD can increase your savings in,

1. Energy
2. Operational costs
3. Downtime
4. Maintenance
5. Raw materials

Importance of using a VSD:

The significance of electric motors in our homes, workplaces, and daily lives is crucial. Whether for work or play, we rely on them to transport and operate our essential necessities.

These motors are all powered by electrical current. To fulfil their function of supplying torque as well as speed, they require the corresponding quantity of electric energy. To provide the required torque or velocity, each of these motors requires power. Mechanical controls will be employed to slow shift or regulate output if the torque or speed is deemed excessively high or low. The end effect is inefficiency, with plenty of resources and effort going to waste. Motor speed should be just what is needed for the procedure. Not having a more refined method of regulating velocity results in significant energy waste, which is bad for business. Along with VSD and VFD, Group Nish is also a popular supplier of MV Drives for Chemical Industries in India.

We say that either the torque or the speed is controlled when referring to a variable speed drive. The speed of the variable speed drive is set by the load while it is in torque control mode. In a similar vein, when running in speed control mode, the torque is dependent on the load.

Here’s why you should invest in variable speed drives (VSDs) to improve the energy efficiency of your various applications, such as pump, fan, conveyor and compressor systems:

1. Improved efficiency in Operations:

Because the system controlled by drives can be automated, the need for human labour is avoided, which results in savings in man-hours as well as costs associated with labour.

2. Cost reductions on the electricity bill:

Variable speed drives only utilise the amount of energy that is necessary by running the motors at partial load. This can result in savings of up to 50 per cent in the amount of energy that the drive system requires to operate.

3. Savings in capital investment:

Substantial savings on electricity consumption enable a rapid return on investment for the VSD, which can occur in fan as well as pump applications even within a few short months of having the device installed.

4. Maintenance Cost Saving:

Drives allow for the mechanical equipment to be subjected to less stress during startup and operation, which in turn ensures that the equipment will last for a longer period of time.

Not only is it possible to make this kind of substantial gain in large-scale industrial activities, but it's also possible in smaller establishments. Utilizing our no-cost EnergySave Calculator for compressors, fans, and pumps enables you to make an estimate of the potential energy and cost savings that could be obtained by employing a low voltage VSD control as well as AC Drives for Chemical Industries in India rather than more conventional methods such as throttles and valves.
