Abstract
An energy storage system particularly adapted for mobile x-ray units which uses electrical energy from an ordinary 110 volt wall outlet, stores it as mechanical energy, and then converts part of the mechanical energy back to electrical energy in a short period of time. The mechanical energy is stored in flywheels which are also parts of a generator which converts mechanical to electrical energy as required.
Claims4
An energy storage system comprising:
- (a) a case;
- (b) a motor having a vertical spindle extending therefrom, said motor converting a low power source of electrical energy into mechanical energy, said motor mounted in said case and detachably connected to said low power source;
- (c) a cylindrical flywheel for storing said mechanical energy rotatably mounted in said case having a central vertical shaft about which said flywheel operates and a ring extension rigidly connecting said shaft to said flywheel, said flywheel having laminate construction of a plurality of concentric cylinders;
- (d) a gear system for transferring rotary motion of said spindle into rotary motion of said flywheel about said shaft whereby an idler gear is disengagably connected between a motor gear mounted on said spindle and a flywheel gear mounted upon an extension of said shaft, said motor gear disengagably connected with said motor;
- and
- (e) means for rapidly discharging said mechanical energy as high power electrical energy, said high power electrical discharge having very short time duration and constant voltage such that many such discharges occur before significant degradation of said stored mechanical energy occurs.
