## Abstract

A linear a-c generator according to the present invention comprises a stationary magnetic system and n channels filled with liquid metal, each channel being partially located in the gap of the stationary magnetic system. All the channels are connected hydraulically in series and form a closed hermetically sealed loop. The channels accommodate armatures reciprocating therein. Electrodes are used for taking off the energy generated in the armatures. The invention makes it possible to improve the weight-dimensional characteristics of generators of this type and to provide for high efficiency and a long service life.

## Claims

### Claim 1

A linear a-c generator comprising: a stationary magnetic system having a magnetic circuit; n channels filled with liquid metal, each of said n channels being partially located in a gap of said stationary magnetic system and all of said channels being connected hydraulically in series to form a closed hermetically sealed loop; armatures located in said channels and being reciprocal therein; and electrodes for taking off the energy generated in said armatures.

### Claim 2 (depends on 1)

A linear a-c generator as claimed in claim 1, further comprising a power take-off transformer having a primary winding and a core, said electrodes and channels being electrically short-circuited and forming said primary winding of said power take-off transformer, a part of said core being aligned with the magnetic circuit of said stationary magnetic system.

### Claim 3 (depends on 1)

A linear a-c generator as claimed in claim 1, wherein the sections of said channels housing said armatures are located so that they form faces of a rectangular prism having a base in the form of a regular polygon.

### Claim 4 (depends on 2)

A linear a-c generator as claimed in claim 2, wherein the sections of said channel housing said armatures are arranged so that they form faces of a rectangular prism having a base in the form of a regular polygon.
