Title:
FLYWHEEL TYPE ENERGY STORING DEVICE
Document Type and Number:
Japanese Patent JPH0236740
Kind Code:
A
Abstract:
PURPOSE: To improve the efficiency and the assembling performance by employing an induction motor in a generator motor section thereby enabling high speed rotation of a flywheel.
CONSTITUTION: When power is fed from the outside to a coil 59 of a stator core 58, magnetic induction is produced between the stator core 58 and a rotor core 62 and thereby a rotary body 65 rotates around a pivot shaft 56 at a high speed. A flywheel 64 rotating at a high speed stores electrical energy in the form of kinetic energy, which is converted into electrical energy as required and fed as power to a load. During idling operation, iron loss in the stator core 58 can be suppressed by lowering the input terminal voltage.
