Depending on the require\u00adments and appli\u00adca\u00adtion, either an AC, EC, or DC motor is used \u2013 mainly as an external rotor motor. This is because the impeller can be mounted directly onto the rotor. This makes the impeller motor unit extremely short and compact, creating more space for air flow.<\/p>\n\n\n\n
Of course, the impeller is an elemen\u00adtary compo\u00adnent. The impeller is crucial for air accel\u00ader\u00ada\u00adtion and gener\u00adating work in the form of pres\u00adsure. Across all of the designs, the air is drawn in parallel to the axis of rota\u00adtion and flows out again according to the blade char\u00adac\u00adter\u00adis\u00adtics. For axial fans, for example, the air flows out mainly parallel to the axis. For safety reasons, the impeller blades are often fitted with guard grills so that no one can hurt them\u00adselves on them. To achieve good effi\u00adciency, an axial fan\u2019s impeller should be posi\u00adtioned in a fan housing that has been aero\u00addy\u00adnam\u00adi\u00adcally opti\u00admized. Together with a front plate, this ensures air flow control and provides the sepa\u00adra\u00adtion required between the intake and outlet sides. <\/p>\n\n\n\n
Due to the different types of flow through the impeller, the fan designs have different oper\u00adating char\u00adac\u00adter\u00adis\u00adtics. If oper\u00adated using an EC motor, commu\u00adta\u00adtion elec\u00adtronics are required. The sensors inte\u00adgrated in the motor allow the elec\u00adtronics to precisely detect the posi\u00adtion of the rotor in rela\u00adtion to the coils. To that effect, the coils are ener\u00adgized and the rotor is turned. In addi\u00adtion, the built-in elec\u00adtronics process control signals and store status infor\u00adma\u00adtion.<\/p>\n\n\n\n
Regard\u00adless of the fan type and purpose, addi\u00adtional noise insu\u00adla\u00adtion is useful for oper\u00ada\u00adtion in noise-sensi\u00adtive areas. For this purpose, a Flow\u00adGrid is mounted on the intake side of the fans \u2013 for a lower noise level and a dras\u00adti\u00adcally damp\u00adened blade passing noise. As a result, the air perfor\u00admance remains unchanged. <\/p>\n\n\n\n
If all of the parts are opti\u00admally matched, the fan is able to meet the require\u00adments with respect to oper\u00adating condi\u00adtions, perfor\u00admance, and envi\u00adron\u00admental influ\u00adences.<\/p>\n","protected":false},"excerpt":{"rendered":"
