The SWIFT Drive solves problems that are normally encountered when using gearless elevator systems. The SWIFT Drive is classified as a VVDC, or Variable Voltage Direct Current drive. This engineering marvel allows the drive to recyle it's unused energy. It's clearly the best choice for modernizing high-speed gearless elevator systems.
With all of the electronic devices in today's buildings, energy usage has become high-priority. As our world, and every-day devices, become more technological, and more power-hungry, a building's power factor will usually deminish. Power companies tend to offer discounts to customers who correct their energy usages to best suit the grid, and inversely, will surcharge those who don't.
As with any operation, things should run smoothly and efficiently. To reach this goal in the world of energy, voltage and current need to be synchronized, yielding an ideal power factor of 1.0. When this rate changes, it means that energy is being lost on one side of the equation, whether it be volts or amps. If energy is being thrown out, your money is going with it. Most elevator systems run between 0.74 and 0.89, while the SWIFT Drive runs a lot closer to the ideal of 1.0 -- it's good to be unique.
If you've been watching TV and someone used a blender or another appliance has kicked on and you've seen and heard static, you've experienced RFI. RFI can not only disrupt your viewing of your favorite show, but it can shut down critical electronic systems under the right conditions. Most high-speed gearless elevator drives cause a lot of RFI due to their power output, causing disruption to electronics building-wide.
The SWIFT Drive eliminates most, if not all, RFI. In fact, the SWIFT Drive meets and exceeds govermental standards in the United States and Canada, but also on the new, more-stringent, European laws.
Alternating Current electricity is the type of energy that courses through all buildings. Unfortunately, a waveform called Harmonic Distortion can be created in the alternating current that can severely disrupt other devices. It can lead to electronic interference similar to RFI, overheating and meltdown, capacitor explosion and more. The Institute of Electrical and Electronic Engineers (IEEE) have come up with guidelines to reduce these common problems. Their standard, THD (Total Harmonic Distortion), is much lower (5%) than most of the drives that are currently being used. The SWIFT Drive keeps less than 5% THD during it's normal operation, thus protecting sensitive electronic equipment throughout your building.
The SWIFT Drive creates a faster, cleaner, safer and cheaper working environment. On top of all that, it's simple. Increase productivity, increase savings, and improve ride-quality with the SWIFT Drive.
