  • Rotating heating roller of the type having a three phase circumferentially laminated leg core
    Patent number: 4647744
    Abstract: A rotating heating roller includes a laminated core and four circumferential yokes provided on the core. A three-phase winding is mounted on the leg core between the yokes. The winding is divided into three coils and adjacent end parts of the coils are overlapped. These overlapped coil parts generate a higher induced electromotive force when excited than that of the non-overlapped coil parts. The higher electromotive force contributes to a uniform distribution of the surface temperature of the rotating roller.
