Elevator Inverter

Elevator inverter is a device that regulates the motor speed to provide passengers with a comfortable ride. It also helps reduce energy consumption and improve efficiency.

The ZAdyn elevator inverter is specially developed for lift technology, with a wide range of housing designs and universally compact construction. It can be mounted in control cabinets or in elevator shafts.

Cost-effectiveness

An elevator inverter is an energy-efficient and cost-effective power tool for use in an elevator. It uses regenerative energy to save on electricity consumption while in operation and can also help reduce peak loads.

ThyssenKrupp, the world’s largest elevator manufacturer, has developed a simulation software tool to estimate energy savings opportunities for customers. This allows companies to evaluate the potential for implementing regenerative drive technology in new elevators and retrofits.

The software enables regenerative drive systems to store braking energy during low-use periods and use it later in the day when demand is high. This can significantly lower a building’s overall energy use, and it also provides additional functionality because the stored energy can be used to supply other equipment.

In addition, the system can provide backup power in case of a power outage. In this way, the elevator system can operate until the primary source is restored.

Elevator inverters are also available with battery backup features to make them even more cost-effective. The batteries are long-lasting and do not require any maintenance. In the event of a power Elevator inverter cut, the elevator UPS automatically activates the battery mode and starts generating a three-way output that helps to feed connected loads. The transition time between the failure of the main and switching to the backup is only 15 to 20 seconds, which is very convenient.

With the advancements in elevator technology, there are more options than ever before for reducing electricity costs and improving energy efficiency. Among the most effective are regenerative drive systems and electric motors that use Supercapacitors, which allow energy generated during downward travel to be recycled rather than wasted.

These devices are based on a DC/DC converter that supplies the elevator with regenerative energy and can also be equipped with an inverter to generate an AC output for control systems. These inverters provide increased reliability and performance by incorporating a high-voltage diode bridge rectifier with a digital voltage balance that produces a precise voltage for traction drive and motor operation.

This energy-efficient power tool can be installed on existing elevators and retrofitted in new elevators to improve the system’s efficiency. The most effective systems are available for elevators up to 50 floors in height.

Energy-saving

Elevators consume a lot of energy, mainly in standby mode where they are powered on for hours at a time when the equipment is not in use. This can be significantly reduced by installing a power tool, such as an elevator inverter, that can shut down the electric supply to the system during standby mode.

Elevator inverters are designed to reduce energy consumption by controlling the speed of the motors, a process known as frequency conversion. The device also regulates the voltage and frequency output to drive the motor.

In addition, the inverter can be programmed to perform a variety of functions, including regenerative mode, which turns the motor backward during descent so that it acts as a generator to feed electricity into the building’s electrical system. This is a highly effective solution for reducing power usage in high-rise buildings where elevators are frequently used.

The United States Department of Energy (DOE) has issued minimum energy conservation standards for a variety of appliances and equipment, which has resulted in significant savings for consumers. In addition, there are a number of government and utility incentives that can be used to encourage the adoption of more efficient elevators.

Another energy-saving technology is a regenerative drive, which is used on modern systems to transform the braking force from the counterweight and the loaded cab into electricity that can be sent to uses within the building. This can be used in new or retrofitted systems to dramatically improve the energy efficiency of existing elevators.

Several companies offer this technology, including ThyssenKrupp Elevator, KONE, Otis, and Schindler. Depending on the model of the system, regenerative drives can cut energy consumption by anywhere from 40 percent to 75 percent, according to Steve Snedegar, senior manager of service sales and marketing for Otis Elevators.

Regenerative drives are also an effective way to keep a traction elevator operating in the event of an outage, as they can recharge batteries that store energy and continue to run the elevator without using power from the grid. This can help minimize downtime and increase safety for building occupants while also lowering the overall cost of running the elevator.

Safety

Inverters are a great safety tool for elevators because they limit the potential for malfunctions such as accelerating or slowing down, overloading of the elevator cabin and stopping on the wrong floor. Moreover, they also reduce electricity costs.

An inverter works by changing the current through the motor. This way, it prevents overheating and improves the system’s durability. It is especially important for elevators with high-frequency motors.

The inverter is a high-tech product that is easy to install and operate. It is designed to protect the elevator motor from a number of issues, including overheating and lightning strikes.

Another way that the inverter can help protect the elevator is by preventing overvoltage and overcurrent. These can be caused by a number of factors, such as lightning or a solar flare.

To avoid this, you should ensure Elevator inverter that your inverter is rated for the current and voltage that it is being used for. You can do this by checking the manufacturer’s manual and using appropriate fuses or circuit breakers to protect your inverter.

Alternatively, you can purchase a battery backup for your elevator that will ensure that your elevator stays running if the main source of power is interrupted. This type of back-up power system is also a good option for elevators in multi-story buildings because it provides at least 90 minutes of back-up power.

In addition to the back-up power system, the elevator control system also needs to have backup power to run the system in case of an electrical outage or a fire. This is why the inverter has a power lock-out timer that disconnects the load from normal control power when an irregularity is detected.

The inverter then moves the elevator to the battery backup and starts charging the batteries once the primary power supply is restored. This is a quick process that only takes 15 to 20 seconds.

Aside from providing backup power, an elevator inverter can also keep track of your elevator’s speed, enabling you to see the position of your vehicle and correct the speed if needed. This can save you a significant amount of money and make your life easier.

Efficiency

Elevators play a crucial role in transporting goods and people from one floor to another. They are used in commercial centers, buildings and even households. However, they consume large amounts of power.

The energy consumed during travel depends on the number of trips and also on the elevator’s design. An inverter can reduce the energy consumption during travel by 20 percent compared to the conventional system, and can save as much as 60 percent in standby mode.

Frequency inverters have been around for quite some time, but their potential has not been fully exploited. Without a frequency inverter, the pump’s drive motor runs at full speed right from the start. The pump then uses the oil displaced from the cylinder to control its travel curve, a process known as “energy dissipation”. As a result, the pump can only pump as much oil as it needs for an ideal travel curve and the extra oil produced during braking can be fed back into the tank.

This energy can be re-used in the elevator, or it can be fed into the grid. The latter requires a special agreement with the electricity supplier.

A new joint development from Blain Hydraulics and Yaskawa, which uses a Supercap with frequency inverter and a hydraulic valve from Blain, has the potential to make hydraulic lifts more efficient than ever. The solution combines a frequency inverter from Yaskawa with a Supercap from Blain and is a cost-effective and simple to install package that will revolutionize the way hydraulic lifts operate.

For traction MRL elevators, using composite materials in the carrier and cylinder could reduce motor power by 58%. Applying traffic balancing by increasing down travel and decreasing up travel could further decrease motor size.

When reducing the down travel, the elevator’s cycle time can be reduced by 0.3 s and maximum up travel times by 4.2 s. This results in a 44% reduction in motor power compared to Design I.

Moreover, the energy required for running the lift in standby mode can be greatly reduced. This would translate to an average of 10,000 kWh per year for a 2 kW lift in standby mode. The energy savings can be achieved in a variety of ways, from regenerative braking to a destination dispatch system.
