A Variable Frequency Drive (VFD) enables precision adjustment of motor rotation speeds to achieve higher performance and efficiency. Whether you’re operating fans, pumps or compressors, or equipment with frequent braking or varying loads, the advantages of switching to drives are immediate and measurable. Utilizing the inherent structure and bus design of the
Siemens tiastar™ MCC allows you to compartmentalize the drive and wiring to segregate and protect portions of your electrical system.
Lowering energy consumption
It is well known that the use of drives offers more efficient use of energy. Providing only the necessary speed and power to execute a task is a no-brainer. While motors represent over 65% of the total industrial power demand, some 70% of today’s installed motors do not use optimal motor control. The good news is that almost every company has the potential to tap into enormous energy savings by using drives. The energy savings potential is substantial – up to 70%. Drives pay for themselves in saved energy costs in a short period of time – allowing you to pocket the ongoing savings.
Getting it back and paying it forward through energy regeneration
When a motor spins down or a load is pushing the motor (rather than the other way around), in conventional systems the energy is lost in the form of heat. But regenerative in-feed drive technology allows capturing the kinetic energy normally wasted when stopping or cycling a motor, to be returned back to the facility's electrical power grid. This reduces overall power demand, ultimately lowering energy costs, and helping the environment.
Improving control, increasing uptime
Variable frequency drives offer greater responsiveness and smoother operation than alternatives such as pressure and flow adjustment methods. In addition, an intelligent operator panel significantly simplifies operator control. Having a drive on your communication network, especially in tandem with a “Smart” MCC, provides early warning codes to predict possible problems. This allows you to act on potential situations to avoid production losses
Extend the life expectancy of your capital assets by reducing wear-and-tear, such as dry running and overload. The advanced system controls and absence of moving parts that require maintenance/repairs lengthen mechanical life and reliability. In some applications, drives options may “clean” existing power conditions, eliminating harmonic and distortion problems that can have a negative effect on other components in the system. Options are available allowing harmonic correction to meet IEEE 519 standards.
