Description
Technical field
The utility model relates to a kind of elevator traction machine motor, especially takes the permanent magnetic synchronous traction machine motor of air blast cooling.
Background technology
For a long time, elevator traction machine mainly uses asynchronous machine to drive, and permagnetic synchronous motor higher and energy-conserving and environment-protective because of its efficient in recent years are used widely in traction machine driving field.The ratio that the use permagnetic synchronous motor drives in the new elevator of installing has surpassed the ratio of using asynchronous machine, and using permagnetic synchronous motor to drive will become traction machine main flow driving type.At present, the traction machine that known use permagnetic synchronous motor drives has two types, be respectively have a reducing gear gear permanent magnetic synchronous traction machine and direct-drive type gearless permanent-magnet synchronous traction machine arranged.
For being used for driving traction machine, and the motor that belongs to the permanent-magnet synchronous type, temperature rise is too high to be to influence one of its stable principal element, the radiating mode of known permagnetic synchronous motor has two kinds, a kind of is natural air cooled, promptly do not take any compulsive measures of quickening to dispel the heat of being used to, only rely on casing surface heat loss through radiation under nature; Another kind is to add fan to carry out the air blast cooling heat radiation, and fan is the electric drive fan of absolute construction.
The permanent magnetic synchronous traction machine that has reducing gear is to adopt reducing gears such as worm and gear, helical gear or planetary gear to carry out speed change, and too high because of the reducing gear cost, such traction machine is used less in elevator.The permagnetic synchronous motor that drives such traction machine all is to take natural air cooled mode to dispel the heat, and does not exist at motor radiating in the electric machine structure and installs additional or improved structure member.
The direct-drive type gearless permanent-magnet synchronous traction machine saves the gear graduation link, use the permagnetic synchronous motor of low speed high torque directly to drive traction steel-cable, because such traction machine rotating speed is low, the radiating mode poor effect of flabellum is installed on rotor, so such permagnetic synchronous motor is taked natural air cooled the heat radiation mostly, radiating effect is poor, in addition, for increasing cooling surface area, cause motor volume bigger, motor cost is higher.
The direct-drive type gearless permanent-magnet synchronous traction machine motor that is applied on a small quantity in the high speed heavy elevator uses fan to carry out the air blast cooling heat radiation, for this class permanent magnetic synchronous traction machine motor, no matter be in motor, winding to be dispelled the heat, still outside casing, casing is dispelled the heat, employed fan is all independently-powered, and independent drive circuit control fan operation need be arranged.The defective of this radiating mode is all easy break-downs of fan control circuitry and fan electromagnetic drive, and needs to add protective circuit in case the motor windings temperature that fan failure caused is too high.
As seen, known permanent magnetic synchronous traction machine motor, either radiating effect is bad, or the radiator structure parts are many, and control is complicated, unstable properties.
Summary of the invention
The purpose of this utility model is: compact conformation is provided, cost is low, stable performance, the air blast cooling permanent magnetic synchronous traction machine motor of good heat dissipation effect, can solve the heat dissipation problem of permanent magnetic synchronous traction machine motor effectively, abundant existing structural member in the integrate motor structure is saved space and material again.
Technical conceive of the present utility model is: motor power directly or by the gear indirect transfer is arrived radiator fan, and the drive fan rotation, thereby motor internal is carried out the air blast cooling heat radiation.
The technical solution of the utility model, provide a kind of permanent magnetic synchronous traction machine motor that is integrated with heat abstractor, comprise motor stator, rotor, rotating shaft, casing, end cap, radiator fan, it is characterized in that permanent magnet is arranged on the rotor, radiator fan places casing or end cap inboard, and the rotation of machine shaft drives the rotation of radiator fan.
In the technical program, providing the motor of power to traction machine is permagnetic synchronous motor, on electric machine casing, have ventilating opening, fan is placed in the casing, electric fan is fixed in rotor or the rotating shaft and coaxial synchronous rotation with it, perhaps, the speed change gear wheel of drive fan is fixed in rotor or the rotating shaft, the rotation of fan and the rotation of motor be disalignment but also asynchronous not only.Can quicken the air flows on casing inner iron core and winding surface during the fan rotation, realize heat radiation electric machine iron core and winding.
A kind of form of implementation of the technical program is to install electric fan on the rotor end-face or on machine shaft additional and with the coaxial synchronous rotation of rotor, quicken the motor internal air flows, thereby motor windings and electric machine iron core are dispelled the heat, and the embodiment of Fig. 1 and Fig. 2 belongs to this type exactly in the accompanying drawing.Especially, use present embodiment in high-speed permanent magnetic synchro traction machine motor, its radiating effect can be better.A feature of this form of implementation is that flabellum is fixed on the rotor end-face or on machine shaft, has saved the pivot structure of fan itself.
The another kind of form of implementation of the technical program is to install additional in rotor end face or rotating shaft and its gear wheel that rotates synchronously, in rotating shaft place of fan design pinion with the coaxial synchronous rotation of flabellum is arranged, described gear wheel and pinion are meshing with each other, make power be delivered to fan by the gear graduation transmission from motor, and the rotating speed that makes fan is greater than rotating speed of motor, the air-flow that is driven by fan dispels the heat to motor windings and electric machine iron core, and the embodiment of Fig. 3 to Fig. 5 belongs to this type exactly in the accompanying drawing.Especially, use present embodiment in low-speed permanent-magnet synchro traction machine motor, its radiating effect can be better.
The embodiment of the technical program can have above-mentioned two kinds of forms of implementation concurrently, and the motor rotor construction type contains inner rotor core and outer-rotor structure.The number of radiator fan is one or more in the technical program, and the material of the change-speed gearing of fan and drive fan includes but not limited to metal, plastics and high tensile strength fibrous material.
The permanent magnetic synchronous traction machine motor of the technical program can be used in escalator, vertical lift elevator, the engineering hoist engine.
The beneficial effect of the technical program is:
1, the heat radiation of the fan of motor belongs to air blast cooling, obviously improves than natural air cooled its radiating effect.For motor, good heat dissipation effect just means can design higher motor heat load, reduces the volume and weight of motor, improves the power density of motor, reduces cost.
2, the type of cooling in the technical program belongs to cold from fanning, the power that the drive fan flabellum rotates comes from machine shaft, do not need to add the independent circuits drive fan, avoided electric wind dispelling to fan the situation that causes the fan stall because of the additional circuit fault, thereby fan performance is more stable.
3, the caloric value of electric machine iron core increases with the increase of motor speed, and for the geared machine of band reduction box, rotating speed of motor is higher, and core loss accounts for larger proportion in total losses.When motor speed increased in the technical program, the rotating speed of fan also increased thereupon, and when promptly the caloric value of electric machine iron core was big, meanwhile the wind dispelling amount of fan was also bigger, can dispel the heat timely and effectively to iron core.
4, can be integrated into electric fan on the rotor, compact conformation is saved the space.
