Rotary motor and production method thereof, and laminated core and production method thereof

An electric motor-driven vehicle has a large wind turbine mounted at the rear of the vehicle that rotates about an axis perpendicular to the axis of the vehicle body. A long venturi tube extends along the upper portion of the vehicle above the passenger cab and directs air flow from the front of the vehicle and impinges it upon an upper portion of the turbine blades. A pair of elongated lower screw-type turbines are contained in separate lower venturi effect tubes extending along the lower side of the vehicle below the passenger cab. Air from the lower venturi effect tubes is impinged upon the large turbine in a direction and at a location to increase the force generated from the upper venturi tube. The turbines drive one or more electric power generators coupled to storage batteries for recharging the batteries.

Venturi effect charging system for automobile batteries

During forward motion of an electrically-powered vehicle, air is captured at the front of the vehicle and channeled to one or more turbines. The air from the turbines is discharged at low pressure regions on the sides and/or rear of the vehicle. The motive power of the air rotates the turbines, which are rotatably engaged with a generator to produce electrical energy that is used to recharge batteries that power the vehicle. The generator is rotatably engaged with a flywheel for storing mechanical energy while the vehicle is in forward motion. When the vehicle slows or stops, the flywheel releases its stored energy to the generators, thereby enabling the generator to continue recharging the batteries. The flywheel enables the generators to provide a more stable and continuous current flow for recharging the batteries.
