Abstract
PURPOSE: To make a functional and economical power supply by providing one spare source at least to the power supply of a multiplicity of motors which have loads of distinct moments of inertia from each other and by controlling the changing with an electronic switch and a mechanical switch.
CONSTITUTION: The loads 17-57, the moments of inertia of which are distinct from each other, are driven by the motors 16-56 which are supplied power from the variable frequency power source 11-51, the electronic switches 12, 13 are used in the source 11 and the mechanical switches 22-52, 23-53 are used in the other sources, the motors are connected with the spare source 61 through the switching units 14-54 and the synchronization controller 18-58. When the spare source 61 is made wait on synchronizing the motor 16 the moment of inertia of which is the least, the power supply 11, if troubled, can be changed to the spare source at high speed. Also, the other group the moment of inertia of which is greater is changed by the mechanical switch on synchronizing the motor at low speed.
