Function and Feature of Elevator Frame Gearless

• Traction Technology

  Gearless elevators utilize a traction system that is based on friction between the metal pulley and the hoist rope. The elevator car is lifted smoothly and silently by this system without the need for a gear reduction. The motor, which is directly attached to the lift shaft, drives the traction wheel. The absence of gears makes the system more efficient.

• Permanent Magnet Motor

  This gearless elevator frame uses a PMDC or a PMSM to drive the elevator car. The motor is known for its strong lifting capacity and energy efficiency. Because of its high efficiency, it consumes about 50% less energy than traditional elevators. This efficiency is made possible by the absence of mechanical losses associated with gear systems. The magnetization of the rotor is permanent, which eliminates the need for excitation power supply. The motor's speed and torque can be controlled with high precision, which allows for smooth and quick stops and starts.

• Reduced Machine Room Footprint

  Gearless elevators don’t need a machine room. Their machines can be installed in the hoistway. Without a machine room, the machine occupies less space. This allows for the efficient use of space in buildings. Reducing the machine room footprint allows more space for the elevator shaft. This increases the number of elevators in a building. The machine room is usually located on the top floor in overhead gearless elevators. This design is called the machine room-less elevator. Redditing the machine room footprint also minimizes the amount of construction required.

• Energy Efficiency

  These elevators consume less energy than traditional traction elevators. This is because their motors are very efficient. The absence of gears also reduces energy loss. They are designed to recycle energy. When the elevator is moving down with a load or up without a load, the energy is returned to the building's electrical system. Regenerative gearless elevators reduce the amount of energy that is consumed.

• High Speed and Smooth Performance

  Gearless elevators travel at very high speeds. Some can move up to 10 meters per second. They are the best choice for tall buildings because of this speed. Smooth performance is characterized by stable rides that have minimal vibrations and jerks. These elevators have strong lifting power and precise control. Their traction system allows them to accelerate and decelerate smoothly. The permanent magnet motors also contribute to this feature.
