1. High efficiency: Due to the permanent magnet motor, the overall mechanical and electrical comprehensive efficiency of the tractor is above 90%, while the traditional worm gear and worm comprehensive efficiency is only about 75%;
2. Low vibration: the motor works almost without vibration;
3. Low noise: Due to the radical change of the traditional way, the overall noise of the tractor is ≤55dB
4. Super energy saving: about 30% energy saving compared with the traditional worm and worm tractor. For example, the power of the traditional 1000kg1.0m/s elevator tractor is 11KW, while that of the permanent magnet synchronous tractor is only 6.7KW.
5. Humanized design: Multi-function LCD screen, Chinese interface, transparent quality of safe operation of the elevator, easy for everyone to understand, can be targeted to quickly find out all hidden dangers.
6. Maintenance-free: The permanent magnet synchronous tractor needs no lubrication and no environmental pollution, making it a real green elevator;
7. Small starting current: only 1.5 times of the rated current;
8. Intelligent: variable frequency driver control, variable frequency and variable voltage speed regulation, reliable operation, high accuracy, because the operation in the synchronous state conversion rate is zero, can greatly improve the operation accuracy;
9. Exquisite structure: beautiful appearance, rotor and brake combined, compact and compact body, with the advantages of light weight and convenient installation. Rear-mounted tilting device solves the structure and appearance of the tilting device and highlights the design concept of humanity.
10. Saving construction cost: the machine room area is only 50% of that of ordinary elevator machine room, which greatly saves the building space and building materials. At the same time, it increases the effective area of the building and improves the design freedom of building aesthetics.
11. Prevent ELECTROMAGNETIC interference: avoid electromagnetic pollution.
