"Single-phase induction motors drive many arbor-mounted cutting tools in
the home workshop. Stationary grinders, table and radial arm circular saws
frequently turn abrasive or cutting disks that are directly mounted on the
motor's spindle. These disks have large inertial moments that allow them
to free wheel for a long time after the power is turned off. A lengthy
coast to complete stop often amounts to a major inconvenience."
