A CLOCK-CONTROLLED CONSTANT-FREQUENCY GENERATOR (CLASSIC REPRINT)

Excerpt from A Clock-Controlled Constant-Frequency GeneratorThese limitations would be avoided by the use of a rotating device which is forced to maintain a rotary motion of constant angular velocity. This device could be used to drive an alternator for the production of alternating current of constant frequency. The use of rotating machinery maintained in synchronism With standard time sig nals from a tuning fork or similar device has two chief advantages. Figrst, the relatively large amount of energy present as energy of rotation assures continuity of operation even though the control mechanism should momentarily fail to function. Second, it can be so arranged that the control mechanism, such as a tuning fork, is no longer forced to carry the entire operating current of the device.Devices embodying some of these principles are on the market. None are available, however, Which have the big h load capacity which it was desired to obtain from the machine to be described here. A synchronous motor-generator set having an ultimate capacity of 4 kw was, therefore, designed to operate in synchronism with time signals from a clock-controlled tuning fork. The principle upon Which this machine operates is briefly as follows.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
