Abstract
The utility model discloses a cooling blower based on a Y series motor, belonging to the motor manufacturing field, comprising a wind-cone, a fan blade and a Y series three-phase asynchronous motor, the cooling blower is characterized in that front and the back end covers with flanges are used, wherein a bracket is fixed in the wind-cone. The Y series three-phase asynchronous motor is arranged onthe bracket, with a sealed back end cover disposed on the back end. An O-shaped sealing ring is arranged between one end of a solid shaft and the front end cover. The shaft is provided with a fan blade mounting flange. The fan blade is disposed on the fan blade mounting flange. The level of protection of the utility model reaches IP55, and the pressure and the blast volume of blown air can meet the demand of the main motor on cooling, which will not affect the service life of the motor.
Description
Technical field
The utility model relates to a kind of cooling blower based on y series motor, belongs to electric manufacturing.
Background technique
The cooling blower of traditional high-power frequency conversion motor institute adapted has two kinds of patterns.A kind of is external rotor electric machine, and 0.5 mm clearance is arranged between the rotor of external rotor electric machine, and security level does not reach IP55.Find to have a large amount of dust to embed this gap in actual use and cause that dragging armature is alive, the load that increases the weight of motor is until the stuck winding coil that burns.The bearing that external rotor electric machine adopted is less than normal, and bearing capacity is relatively poor, and bearing life is too short.In case bearing failure also can cause the stuck winding coil that burns of the rotor of motor.The inefficacy of cooling blower motor can cause main transformer frequency motor to lack the serious consequence of cooling off and burning, and the bigger complaint of client's reflection is more.Another kind of blower fan adopts inner rotor motor but the fan blade insufficient strength causes rotating speed of motor too highly can only not reach 1000 rev/mins, so not high because exist blade root eddy current loss wind to imitate, the blast that blows out, air quantity are all not enough, and influence is to the cooling effect of main motor.
The model utility content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and provide a kind of security level can reach IP55, simultaneously can guarantee the blast that blows out, the cooling needs that air quantity satisfies main motor, and guarantee the cooling blower based on y series motor in the working life of wind-powered electricity generation machine.
The technical scheme in the invention for solving the above technical problem is: should be based on the cooling blower of y series motor, comprise air duct, fan blade and Y series threephase asynchronous, it is characterized in that: adopt forward and backward end cap, support that flange is arranged, described support is fixedly installed in the air duct, Y series threephase asynchronous is fixed on the support, the rear end is provided with Packed rear end cover, between solid shaft one end and the front cover O RunddichtringO is arranged, shaft extension is provided with fan blade mounting flange, and fan blade mounting flange is provided with fan blade.
Leaf blade described in the utility model is a planar, and blade lower end and fan blade mounting flange distance are at least 65mm.
Solid shaft described in the utility model and Y series threephase asynchronous front end joint are provided with seal ring.
The utility model compared with prior art has the following advantages: because the production and processing technology of y series motor mature performance is stable, can bear the Environmental Conditions of bad working environments, the life-span is longer.Can better be applicable to the cooling blower of high-power frequency conversion motor, change 1400 rev/mins of scooters.The back-end sealing of motor is provided with rear end cover, and front end is provided with front cover and adds seal ring, has therefore significantly reduced the dust embedding, has improved security level.The distance that the blade lower end of fan blade and fan blade mounting flange are certain at interval, so there is not blade root eddy current loss in the working procedure, wind is imitated high, air pressure air flow also can satisfy the cooling needs of main motor.
