... in Fig. 11.20 . During spinning, the metal is deformed in a small, rather than a large, area. A large portion of the blank is unsupported, especially during the early stages of the process. For thin sections, the tool forces can be applied manually to the driven blank. Power spinning uses mechanical...

Accordingly, when starting, excessive motor inrush currents required are brought to lower levels through the use of a reduced-voltage starter. Moreover, the power needed to spin the heavy rotor is the same, whether at light load or full power...
