ELECTRIC DRIVE FOR VEHICLES Russian patent published in 2024 - IPC B60K7/00 H02K16/04 

FIELD: electric motors.

SUBSTANCE: in electric drive for vehicles stator is made with circular magnetic conductor, on which even number of permanent magnets with the same pitch and alternating polarity is fixed. Rotor has toothed electromagnets with coils and is separated from the stator by an air gap. Distribution header is fixed on the stator housing and has current-conducting plates arranged along the circumference, connected with alternation of polarity to a constant current source and separated by dielectric gaps. Current collectors have contact with collector plates and are connected to outputs of electromagnet windings. Number of permanent magnets of the stator (n) is 10+6⋅k, where k is any non-negative integer. Number of toothed electromagnets is equal to three, where each of them has the same number of coils (m), according to the ratio m=(n-1):3. Electromagnets are connected according to a three-phase scheme, when the beginning and end of the winding of each electromagnet are connected to current collectors located opposite each other.

EFFECT: higher efficiency and reliability.
