SYNCHRONOUS JET-ENGINE Russian patent published in 2009 - IPC H02K1/14 H02K19/10 

FIELD: electricity; motors and pumps.

SUBSTANCE: synchronous jet-engine (1) with rotor (3) and stator (6) and stator core (12) is provided with coiled cores (11) and consists of superimposed stator plates (22). The stator plates (22) cover less than the main surface of stator core (12). As a result, an empty void is formed (25). This void is connected with the external edge of stator core. The superimposed stator plates (22) are changed cyclically from one position to another to form reed parts of plates in the form of cooling ribs. The multi-sided stator plate is provided for the main surface. According to the invention, the stator plate (22) has full angle to make swelling (16) taking into account it's alteration around the circuit. The swelling is opposite to the coiled core and has side walls in radial direction, which are parallel to each other. Also, the swelling has empty area (25) within the next angle (24) of the circumferential direction, which contributes to swelling (16) in the finished stator (6). Besides, the width between swelling sides corresponds to 1.2 - 1.7 - divisible width value of the corresponding coiled core.

EFFECT: improved resonant characteristic of synchronous jet-engine; reduced weight and improved cooling, effective use of plate material for stator core production.
