Description
Technical field
The utility model relates to solid inner-rotor-type gearless permanent-magnet synchronous traction machine for a kind of elevator gearless permanent-magnet synchronous traction machine, particularly a kind of villa elevator.Belong to elevator drive technical field.
Background technology
At present, along with the rapid economic development of China, villa real estate project increasing, demand and the driving arrangement of customer to villa elevator also constantly rises.Gearless permanent-magnet synchronous traction machine have the energy, volume of saving little, operate steadily, noise is low, the advantage such as non-maintaining, very general as the driving arrangement of elevator.Therefore, developing the towing machine that is applied to villa elevator is a kind of trend.
According to patent documentation report, the minitype permanent magnetism synchro traction machine of record has a lot, if patent publication No. is CN 1850577A " minitype permanent magnetism synchronization gear wheel free traction machine ", has introduced a kind of villa elevator towing machine, and this towing machine is outer-rotor structure.Traction sheave and axle are integral type casting, the difficulty of processing of main shaft is increased, and traction sheave are consumable accessory, once wearing and tearing need to be separated stator and rotor completely, just replaceable, maintenance and part replacement cost are higher.Although the oad of its main frame is smaller, just there is relative advantage at complete machine thickness direction, axle center height is approximately 390mm left and right, and complete machine height does not reduce, and does not save height space.For machine room motor, designing requirement height of main frame is less, more can reduce space, building utilization rate could be higher, therefore, the height that more can meet villa elevator machine room is little, occupy little space install and use requirement, just more can obtain user's favor.
Patent publication No. be CN 101168423A's " minitype permanent magnetism synchronization gear wheel free traction machine ", disclosing main frame is the structure of traction sheave in middle double bracing and additional axle head supplemental support.It adopts traditional inner rotor core.Be subject to the restriction of structural arrangement, although with above-mentioned towing machine comparison, main frame profile is less, relative thickness and height dimension are also less, because total belongs to supported at three point, have three bearings, therefore if the requirement of working accuracy out of reach just there will be the problem of location.Equally, this main frame is changed also more complicated of traction sheave, whole axle system all will need to be pulled down from main frame, assemble more difficultly, and after service cost is higher accordingly.Main shaft adopts the form of castellated shaft to match with plate disc brake, for main shaft, processes more complicatedly, once that the finish size of male splines and precision can not meet the demands or use is impaired, main shaft will be scrapped.So, not only reduce the yield rate of main shaft, and if main spindle multiple spline damage, need to change whole main shaft, will cause the waste of material.
For the fixed form of permanent magnet in main rotor parts, be mostly permanent magnet and be positioned at surperficial surface-mount type structure unshakable in one's determination, also there is the damascene structures that permanent magnet is inserted to rotor core inside.Damascene structures rotor leakage coefficient is large, has reduced efficiency and the power factor of motor, and therefore, surface-mount type structure is more economic and practical.
Patent publication No. is that CN 102111029A " adopts the rotor structure for permanent magnet motor of punching component fixed permanent magnet ", its technical scheme be by non-magnetic blanked part as every magnetic stripe, utilize bolt by the bolt hole on blanked part, permanent magnet circumference to be divided equally and is fixed on iron core.Fixedly there is potential safety hazard in this kind, due to blanked part thinner thickness, in the time that motor speed is higher, the centnifugal force of one or more permanent magnet is larger, has the potential risk of blanked part insufficient pressure, and permanent magnet may be along circumference vibration.
Patent announcement number is CN 202111546U " magnetic steel fixing device of synchronous electric motor rotor ", provide a kind of sleeve to be axially arranged with magnet steel location groove, outside face unshakable in one's determination is provided with the fixing magnet steel of mode of interior location groove vertically, this kind of structure is because magnet steel is equipped with sleeve outward, therefore can increase air gap, make Efficiency Decreasing, the location groove accuracy requirement that core exterior surface is provided with is high, and therefore difficulty of processing is bigger than normal.
