Variable speed externally ventilated async. motor - has fan motor housing made integral with mounting shield or motor

摘要

The externally ventilated variable speed a synchronous motro with a squirrel-cage rotor is designed largely to exclude vibrations of the motor shaft commensurate with a compact layout that allows accessories such as , for example, tachogenerators etc. to be installed. Thus, the housing of the fan (ventilator) motor is made part of the mounting shield (plate) of the asynchronous motor that receives the first bearing of the motor shaft as well as the first bearing of the hollow shaft section. The motor shaft second bearing is mounted, together with the hollow shaft section second bearing, in the dust hood that connects to the mounting shield of the motor.
