Description

For the outer rotor gearless machine of cage lifter
Technical field
The present invention relates to a kind of gearless elevator drag machine for cage lifter, in particular to a kind of cage lifter being applicable to skyscraper, there is operation at a high speed and stronger overload capacity, the gearless elevator drag machine that also can efficiently and reliably run while saving natural resources.
Background technology
Cage lifter in the market adopts permanent magnetic synchronous traction machine mostly, and the permanent magnet rare earth material consumption needed for it is also large, thus causes a large amount of energy resource consumptions.Therefore, how to make the towing machine being applied to cage lifter can reach energy-saving run effect and reduce costs, become one of those skilled in the art's problem demanding prompt solution.Synchro traction machine has the large feature of moment, so be used widely at elevator industry.But, its rotating speed is lower, if its rotating speed is improved, due to the interference from the external world relatively many (comprise on-the-spot voltage disturbance, suddenly load increase, coder and motor produce displacement, magnet steel produce and demagnetize), so be very easy to produce magnetic collapse, and then produce sizable potential safety hazard.If select asynchronous towing machine, although the potential safety hazard such as not demagnetize, run also relatively reliable because its power factor and efficiency low, do not meet the industry policy that national energy-saving reduces discharging.Therefore, how to make the towing machine being applied to cage lifter can reach the effect of saving natural resources, also can run at high speed, reliably, also become one of those skilled in the art's problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of outer rotor gearless machine for cage lifter, it is applicable to the cage lifter as skyscraper, has operation at a high speed and stronger overload capacity, also can efficiently and reliably run while saving natural resources.
For solving the problem, the present invention is used for the outer rotor gearless machine of cage lifter, includes: be positioned at coaxial line and the stop mechanism, carrying means and the driver train that connect successively; Also include: machine bed, which support described carrying means and driver train, meanwhile, described stop mechanism is also installed on described machine bed; Being provided with in described machine bed in radial direction is the bearing of the paired setting that described carrying means provides support; Be provided with as described driver train provides the outer rotor of driving asynchronous driven unit in described machine bed is further.
As a preferred embodiment of the present invention, described driver train comprises three phase asynchronous motor.
As a preferred embodiment of the present invention, the asynchronous driven unit of described outer rotor include be connected with described machine bed rotor rack, in be located at described rotor rack and coupledly realize the rotor core of synchronous rotary and be sheathed on interior stator core assemblies for described rotor rack and rotor, this stator core assemblies is fixedly arranged on described machine bed simultaneously.
As a preferred embodiment of the present invention, described rotor core is cast aluminium or cast copper.
As a preferred embodiment of the present invention, described driver train is connected with the coder of rotor core running state described in detection and control further.
As a preferred embodiment of the present invention, described stop mechanism is folding brake, and it is positioned at the periphery of described carrying means, and includes intermeshing handwheel and jiggering gear, and wherein, described jiggering gear is connected with described carrying means further.
Technique effect of the present invention is, utilizes the asynchronous driven unit of outer rotor, has both had the advantages such as operation at a high speed and stronger overload capacity, has again the advantage that Induction Motor-Driven is convenient and reliable.While realizing high-speed cruising, the safety, the integrity problem that occur because permanent magnet demagnetization inefficacy causes can be avoided, thus improve the safety of elevator.
Technique effect of the present invention is also, has effectively evaded external rotor permanent magnet synchronous machine and has expended other metallic materials needed for nature rare earth material and magnet steel in a large number.
Technique effect of the present invention is also, under meeting steel rope footpath is not less than the restriction of 40 times with wheel, substantially reduces the wheel footpath of traction sheave, electric motor starting torque is reduced, power reduction.
Technique effect of the present invention is also, achieves the arrangement of reasonable and compact inner each component.
