Starting or Stopping Control Circuits of Electric Pumps and Multi—functional Protecting Circuits of Motors
In some cases, electric pumps are requested to operate under the special circumstance and conditions continuously for a long time. So it is necessary to use special starting or stopping control circuits. Then It is desined that starting or stopping control circuits and multifunctional protecting circuits which is consist of integrated circuits is introduced in this paper. Also the paper briefly presents the protection circuits of delay to stop motors in the conditon of light-load the protection circuits of classified delay to stop motors in the condition of over-load, and the circuits which can automaticallyre-generate the motors after stopping in the condition of light-load.
