The control circuit comprises: a zero current detection circuit having a polarity detection circuit for outputting a first and a second digital signals and a signal conversion circuit for generating an analog signal; a feedback circuit for generating a driving pulse signal; and a pulse distribution circuit for distributing the driving pulse signal to a first and a second switches according to the first and the second digital signal.
|Self-reciprocating electric motor|
A motor that is distinct in that it is electric and it reciprocates it's own use, exemplifying more power than what is needed in function. Such a motor as to be used in torque to transmission of motion leverage, as well as power generation.
