It is not easy to ensure, normal force is big, stress concentration, and to supporting and positioning has high requirements, and thrust is easily fluctuated with air gap.This
Outside, the mode of braking of wireless elevator is generally accepted clamps disk mode of braking, but braking rail arrangement and driving using T-shaped rail
Source, guide-localization arrangement also the most key technical problem, it is i.e. interrelated and conflicting between them and lead
System, it is mostly important just as the chassis of automobile, suspension and driving, brake arrangement mode, it is necessary to resolve, just may be used afterwards first
To talk about other performance index.
In general, it is above-mentioned using linear motor as the basic structure of the wireless elevator of driving source, only solve basic driver
Power problem, mostly more or less unreasonable there are stress, complex structure and other problems, there is no solve straight drive elevator engineer application
Primary key issue.For example, how to inhibit the problem of intrinsic normal direction attraction of permanent-magnetism linear motor does not influence improving performance again, carry
The reliable brake problem of machine is risen, after guarantee problem and mover and the car carrying of motor working gas gap caused by discontinuity
It rolls, vibration problems, emc issue, influence problem of long stroke guided way machining accuracy and installation condition etc..Thus,
Urgent need finds even more ideal, simple and practical main body topological structure.
