SINGLE-PHASE ALTERNATING AND DIRECT CURRENT ELECTRIC MOTOR Russian patent published in 2009 - IPC H02K27/00 H02K57/00 

FIELD: electrical engineering.

SUBSTANCE: present invention relates to electrical engineering, particularly to single-phase alternating and direct current electric motors. The proposed electric motor has a case, closed by front and rear covers, a shaft and a terminal block. Inside the case there is a vaned motor, the shaft of which passes through an opening in the front cover, the inlet and outlet connecting pipes of which are hydraulically connected to the corresponding channels of a forward and reverse movement switch, which has a case, inside of which there is a slide valve with transfer slots. The inlet channel of the switch is connected to the outlet channel of a cylindrical heating chamber, while the outlet channel is connected to inlet channel of a cylindrical cooling chamber. The chambers are joined together by a pipe, inside of which there is a valve, which opens on the side of the cylindrical heating chamber, which has a cylindrical hollow case, in which is put an electrically insulating heat-resistant frame with coil of nichrome wire, the lead terminals of which are connected to terminals of the terminal block. The cylindrical cooling chamber has a hollow case with an insulating frame fitted in it, on which alternating metallic and semiconductor discs are mounted, each pair of which is insulated by spacer from a similar pair. The lead terminals of metallic discs are connected to each other and to one terminal of the terminal block through a rectifier. The lead terminals of semiconductor discs are connected together and to another terminal of the terminal block through a rectifier. At any polarity of direct current, the rectifier provides for flow of current from the metal to the semiconductor. All the inner cavities of the vaned motor, forward and reverse movement switch, cylindrical heating and cooling chambers and the pipe are filled with mercury or low boiling liquid.

EFFECT: wider field of application, saving non-ferrous metals.
