Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque (rotation), it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
| Feature | Putianan Maglev Automatic Door | Traditional Automatic Door |
|---|---|---|
| Principle | Non-contact magnetic drive, between motor and moving rail there is a 1.5-2mm gap. | Mechanical physical transmission |
| Mute | 1 million Silent test <40dB(A), Cut out the Noise, Enjoy all-day serenity and comfort | Mechanical transmission noise and long-term wear noise. |
| Safety | Accurately monitors door movement, High sensitivity, and rebounds when encountering resistance | Torsional drive, Risk of loss of control. |
| Service life | Reduced Cost of Use, Caelus fewer moving parts and incurs less wear and tear, has a longer life (1 million usage tests) | Easy to wear and high maintenance costs. |
| Installation | Factory pre-adjusted, power-on self-adaptive, ready to use, easy to install | Complex structure, cumbersome and detailed installation. |
| Volume | Slim in Size, takes up little space and can be integrated into various decoration styles. | It occupies a large space, has a complex structure, and has limited installation in some sites. |
| Energy saving | 40W (About 1 kwh per month), small mechanical friction, low loss, low power, high energy efficiency | 100W, 2 times the energy loss |
| Stability | Smoothness-Vector control system, smooth operation without any frustration | The old-fashioned control has poor accuracy and is prone to jamming, and is prone to operating errors after long-term use. |
Our advanced magnetic levitation system eliminates the need for traditional rollers, providing an effortless and maintenance-free operation, ensuring that your patio door system operates smoothly and quietly for years to come. Say goodbye to the hassle and cost of maintenance and enjoy the ultimate convenience and luxury of a no-maintenance patio door with Putianan Doors, low energy linear magnetic drive automatic door opener that is activated, standard intelligent Bluetooth module, support mobile APP control.
The PTA automatic door adopts advanced linear magnetic drive technology, the main control unit adopts vector control algorithm, and the gap between the motor and the moving track is 1.5-2mm, enabling it to slide open and close smoothly and easily without friction.
Mute <= 90kg
High-end aluminum, high-performance magnets and high-quality rollers are perfectly matched and have passed 300,000 wear tests to achieve extremely quiet and smooth operation.
Adopting high-end quality aluminum material, heavy-duty reinforced and thickened engineering outer rail, with high load-bearing grade.
Digital input/output reserved to meet varies scene. Support various intelligent opening methods such as switches, remotes, infrared sensors, radar sensors, passwords/card access control, fingerprint recognition, face recognition, intelligent voice, Bluetooth etc.
★ When the power is on, push the door gently by hand for 2-3cm, and the door will open automatically.
★ Safety anti-pinch: vector control algorithm, microcomputer control system for precise monitoring. If the door encounters an obstacle, it can safely rebound to the fully open position, and then pass the conflict position at a low speed again. If there is no obstacle, it will operate at the normal door opening and closing speed.
★ Unlike traditional automatic doors, there is no other contact point except the pulley and the track, 1 million Silent test <40dB(A), and the operation is very quiet.
★ Installation takes up little space and can be integrated into various decoration styles.
Factory pre-adjusted, power-on self-adaptive, ready to use, easy to install.
A simple yet secure system for areas such as offices, hospitals, elderly homes, banks, commercial locations, and much more.
