There are different types of inverter elevator doors based on the kind of elevator they are used on. These include;
Lift door inverter:
A lift door inverter is an electrical device that controls and synchronizes the opening and closing of lift (elevator) doors. It ensures the safe and efficient operation of the doors by coordinating the movement of two elevator doors.
Lift door inverters are specifically designed for use in passenger and freight elevators. They can be used in hydraulic, traction, and machine-room-less elevators.
Automatic sliding door inverter:
These inverters are used to automatically control and synchronize sliding doors in various applications. The smooth and safe opening and closing of the sliding doors are powered by the motion sensor or push button.
Automatic sliding door inverters are specifically designed for use in elevators with sliding doors. These are elevators found in high-rise buildings and places with heavy traffic.
Gearless door inverter:
Gearless door inverters are used to control and synchronize the movement of elevator doors without using gears. They provide precise control, smooth operation, and faster door opening and closing times. These inverters enhance the efficiency of the elevator system.
Gearless door inverters are used in gearless traction elevators. They are commonly found in modern and high-speed elevators.
Smart door inverter:
Smart door inverters are advanced devices that control and synchronize the opening and closing of elevator doors. They use microprocessors and various sensors to provide safe and efficient operation. They also offer features like internet connectivity and remote monitoring.
Smart door inverters can be used in various types of elevators. They are mostly found in modern elevators.
Speed Control
The speed of the elevator is constant because the DC motor's magnetic field and armature current are controlled by changing the ratio and slip in the induction motor when an elevator inverter is used. This makes it easy for the elevator to stop at different floors.
Soft Start and Stop
The elevator door inverter provides gradual acceleration and deceleration of the elevator. This makes the ride smoother and reduces the jerkiness usually felt when the elevator suddenly stops or starts. It also reduces the mechanical stress that is put on the elevator doors and other components, which can lead to a longer lifespan.
Regenerative Operation
Elevator inverters regenerate allow for regenerative braking. During regenerative braking, the inverter converts the kinetic energy of the elevator car into electrical energy. This energy can be fed back into the building's power grid or stored for later use. This creates energy efficiency. The energy efficiency minimizes the amount of electrical energy needed to power the elevator system, which reduces operational costs.
Multi-Motor Control
One of the features of an elevator door inverter is multi-motor control. The elevator door inverter can control multiple motors simultaneously. This is commonly seen in large elevators or systems that require more than one motor to operate efficiently. When an inverter controls multiple motors, it ensures that they operate in perfect synchrony. This means that each of the motors will work together to distribute the load evenly.
Load Sensing
Most elevator door inverters have load sensing. This feature allows the inverter to adjust the speed and performance of the elevator based on the number of passengers or the weight of the cargo. When the elevator is loaded with passengers, it can increase its speed. Conversely, when it carries little weight, its speed can be reduced to save energy.
Enhanced Safety Features
Elevator safety is very important. Therefore, inverters have some features that enhance the safety of the passengers. For instance, in case of power failure, the inverter can automatically bring the elevator to a safe stop. Also, it can prevent motor overheating by continuously monitoring the temperature and automatically reducing the power output.
The global market for elevator door inverters has grown significantly. The growth is predicted to keep rising because of the high demand for efficient and safe vertical transportation systems. In addition to this, there are numerous applications of elevator inverters, including:
Commercial Buildings
Elevators are very important in the transportation of people and goods in large and tall commercial buildings. In this application, the door inverter is used to control and synchronize the movement of the elevator doors. This ensures smooth opening and closing. The result is improved efficiency and enhanced safety.
Hotels and Hospitality Industry
In the hotel industry, elevator systems are used to move guests and their luggage. The elevator door inverter ensures quick and efficient elevator operations. This enhances guest experience and satisfaction.
Residential Buildings
Inverters for elevators are commonly found in high-rise and luxury residential buildings. Here, they ensure smooth and quiet elevator operations. This provides convenience and comfort to the residents.
Healthcare Facilities
Hospitals and healthcare centers rely heavily on elevator systems. They are used to transport patients, medical supplies, and equipment. The inverter is essential for elevators in this case to ensure fast and reliable transportation. This is critical for patient care and medical operations.
Shopping Malls and Retail Centers
In large retail stores and shopping centers, elevators are necessary for the movement of customers. They also transport merchandise between floors. The inverter ensures efficient and high-capacity elevator operations. This facilitates a smooth shopping experience.
Industrial Applications
Elevators are important in the transportation of materials and personnel in factories, warehouses, and other industrial facilities. The inverter is important in controlling heavy-duty elevators. This ensures reliable and efficient transport of goods and materials.
Public Infrastructure
Elevators are used in public facilities like airports, train stations, and government buildings. Here, the inverters ensure efficient movement of people and luggage. This includes those with disabilities or limited mobility. Therefore, enhancing accessibility and convenience.
Parking Garages and Automated Parking Systems
In automated parking systems and multi-story parking garages, the elevator systems are used to park and retrieve vehicles. The inverter controls the elevator doors and ensures quick and accurate operations. This minimizes vehicle waiting times and improves parking efficiency.
Smart and Energy-Efficient Buildings
In modern buildings, advanced elevator systems are integrated with building management systems. The aim is to optimize energy consumption and efficiency. The inverter plays an important role in controlling the elevator doors. This ensures smooth operation and energy efficiency.
Price
When it comes to choosing an elevator door inverter for sale, price is always an important consideration. This is especially true for large projects or when multiple elevators need to be upgraded. In these cases, a more affordable inverter option could make a significant difference in overall project costs.
Technical specifications
Another thing business owners should look at when choosing an elevator door inverter is the technical specifications. Each type of inverter has specific features that make them suitable for particular types of elevators. Therefore, it is important to choose an inverter with all the required features for the intended application.
Quality and reliability
It goes without saying that the quality and reliability of the elevator door inverter play a crucial role in its selection. In this case, it is advisable to check the reviews and ratings of the selected inverter to ensure it will perform as expected.
Customer support
The process of buying an elevator door inverter for resale requires a high level of customer support from the manufacturer. This is because the buyer will need to consult with the manufacturer to determine the best inverter for their needs. They will also need technical support in case anything goes wrong.
Installation and maintenance
Another important consideration when buying an elevator door inverter for resale is the installation and maintenance requirements. Here, it is important to choose an inverter that will not require a lot of maintenance. Also, the inverter should be easy to install to reduce the overall project costs.
