Abstract

PURPOSE: To prevent a motor from rotating within a fixed period of time at non- load and rotate it over a fixed period of time at inertia and wear loads, during power failure, respectively, by applying a wear breaker to always give braking and a flywheel to the rotor.
CONSTITUTION: An annular break disk 6 is fixed to an axis of rotation 4 and made of metals with wear effects. Since one side of this disc 6 is pressed by a coil spring 8 which is set up at the side end of a frame 5 and by one or a number of break shoes 7, a breaking effect always operates in the axis of rotation 4. A flywheel 10 is also fixed to the axis of rotation 4. When power goes off, such structure permits a motor to stop rotating within a fixed period of time at non-load and to rotate above a limited r.p.m. when loads consisting of inertia and wear loads are connected
