Motor generally includes variable-frequency motor and non-frequency motor, but not variable-frequency motor can be connected in series frequency converter at outside motor when needing converting operation, to realize that converting operation satisfies its user demand.Particularly, the motor of air compressor is Y400-10 type threephase asynchronous machine, and its power is 250KW, and rated frequency is 50Hz, and this motor is wind formula internally cooled, i.e. rotating shaft at motor is equipped with cooling fan.When the Frequency Converter Control motor frequency conversion moves, the frequency change of the running frequency of motor below its power frequency (50Hz) reaches, the rotating speed of motor is corresponding with frequency.Owing to the cooling fan of the electric machine built-in rotation speed change along with motor changes, then the exhaust air rate of motor also changes thereupon.Under the state of motor low-frequency operation, the rotating speed of motor is lower, and the rotating speed of cooling fan is also lower, cause the heat dissipation capacity of motor to reduce, the temperature of motor raises, and affects the life-span of motor, and easily cause motor to damage, not only impact is produced, and can produce certain maintenance cost.
In the prior art, normally connect fan at outside motor for the solution of the radiating mode of motor under the low-frequency operation state, the shell of motor is carried out cooling heat dissipation, its radiating effect is undesirable, and cause larger power consumption, take up room and the place.
The utility model content
The purpose of this utility model provides a kind of motor, and the thermal diffusivity of this motor is better, can satisfy the radiating requirements of motor under the state of converting operation.
To achieve these goals, the utility model provides a kind of motor, and this motor comprises rotating shaft and housing, has air inlet and exhaust outlet on this housing, and wherein, described exhaust outlet is provided with radiator fan.
Preferably, described exhaust outlet and described radiator fan are a plurality of, and these a plurality of exhaust outlets lay respectively at the both sides of described housing, and described a plurality of radiator fans are separately positioned on described a plurality of exhaust outlet.
Preferably, described motor has control switch, and described radiator fan is electrically connected with described control switch.
Preferably, described motor is the non-frequency motor, and the described motor frequency converter outer with being arranged on this housing be electrically connected, and described control switch is electrically connected with described frequency converter.
Preferably, described motor has cooling fan, and this cooling fan is installed in an end of described rotating shaft and is positioned at described housing.
Preferably, the position of described cooling fan is corresponding with the position of described exhaust outlet.
Pass through technique scheme, because the exhaust outlet on the housing of motor is installed radiator fan, this radiator fan can be by power drives independently, also can be driven by the external power supply of motor, so that the running of radiator fan is not subjected to the impact of the rotating speed of motor, its exhaust air rate can be along with the variation of the operating state of motor and is changed.Under the state of motor frequency conversion running, the exhaust air rate of radiator fan remains unchanged, so that the heat dissipation capacity of motor increases, satisfies the radiating requirements of motor under the state of converting operation, to guarantee that electric machine temperature rise is lower, prolongs electrical machinery life.
Other feature and advantage of the present utility model will partly be described in detail in embodiment subsequently.
