WebChoice of specific magnetic loading. Advantages and Dis-advantages of choosing higher values specific magnetic loading WebThe magnetizing current of the motor depends on the specific magnetic loading and the air gap length of the machine. A large air-gap length leads to higher magnetizing current and poor power factor. A large air-gap length increases the reluctance of the path of the magnetic flux. The reluctance of the magnetic circuit is similar to the ...
