Power system

A power system comprising:

• a base;
• two magnetic bearings mounted on the base;
• a shaft rotatably mounted on the two magnetic bearings;
• a flywheel mounted on the shaft;
• a motor connected with the flywheel;
• an uninterrupted power supply electrically connected with the motor;
• a utility power electrically connected with the uninterrupted power supply;
• a coupling connected with the shaft;
• a speed change device connected with the coupling;
• a generating device connected with the speed change device;
• a load electrically connected with the generating device;
• a recharge rectifier electrically connected with the uninterrupted power supply;
• and
• a reactor electrically connected with the recharge rectifier and the generating device;
• wherein:
• the uninterrupted power supply provides an electric power to the motor;
• the motor drives and rotates the flywheel successively;
• the flywheel has a periphery provided with a conic portion;
• the conic portion of the flywheel has a dimension reduced from a center toward two sides of the conic portion symmetrically;
• the flywheel has an interior provided with two concave portions which are arranged symmetrically;
• the flywheel is provided with a fixed portion secured on the shaft;
• the fixed portion of the flywheel is arranged between the two concave portions;
• the fixed portion of the flywheel has a center provided with a through hole allowing passage of the shaft;
• the shaft is rotated successively by the inertia force produced by the flywheel;
• the power system further comprises two fastening members mounted on the fixed portion of the flywheel and secured on the shaft to secure the fixed portion of the flywheel to the shaft;
• the recharge rectifier delivers an electric energy from the generating device into the uninterrupted power supply so that the uninterrupted power supply provides the electric power to the motor for rotating the flywheel.
