Technical Field

Invention relates to variable winding system for electrical engines in general.

Invention particularly relates to variable winding system providing change of magnetic field and torque-rpm balance of number of windings in stator in electrical engines as desired by moving and changing current arm by use of movable mechanism.

State of the Art

The number of windings on the slots in the stator region of the motors is fixed and the motors have a certain speed-torque balance. Depending on the use conditions, various speed-torque needs may occur. In this context, production of current motors in frame of broad scale of speed-torque balance by motor producers meets the needs. However, motors produced in line with such needs may be heavy. This situation negatively affects efficiency.

Said invention discloses a kind of proportional electron speed regulator in electro-magnet form. It discloses an electro-magnet ratio surrounding the magnetic field that is, change in electromagnetic force with the change of the electric current in the ECU regulating windings. It has electronic regulator used together with a generator. It provides opening and closing in proportion to valve located in fuel oil spraying pump. However, said application does not disclose change in magnetic field and torque-rpm balance as desired by changing the number of stator windings by moving the current arm by means of a movable mechanism. In conclusion, developments have been made in variable winding systems for electrical engines and, therefore, new embodiments eliminating the above disadvantages and offering solutions to existing systems are needed.

Detailed Description of Invention

In this detailed description, the preferred embodiments of variable winding system being subject of this invention have been disclosed solely for the purpose of better understanding of the subject and described in a manner not causing any restrictive effect.

The invention, of which illustrative view is given in Figure 1 , is a variable winding system comprising slots (4) located in electrical engines, providing current torque balance by changing stator windings (2) made from conductive material and having current passing through to form magnetic field, located on the stator windings (2) and having magnetic fields therein. In its most basic form, it comprises;

• at least one current arm (1) which has a moving structure and changing current passing through the stator windings (2) by moving,

• at least one moving mechanism (3) moving the current arm (1) as desired and

• at least one current path (5) located on stator windings (2) and whereon current arm (1) is located.

With the movement of the current arm (1), the number of windings on the stator can be varied, thereby providing variability in the speed-torque situations on the engine.

In an alternative embodiment of the invention, the moving mechanism (3) is rotated with an external effect. With the movement of the moving mechanism (3), the current arm (1) moves linearly and moves along the current path (5) by transmitting the current on it to the stator windings (2). With the linear movement of the current arm (1), the current moves over the stator windings (2) and creates a magnetic field. With the movement of the current arm (1), the number of winding in the stator windings (2) changes and accordingly, the magnetic field, torque-rpm balance is controlled. The change in the number of windings with the linear movement of the current arm (1) affects the magnetic field. In alternative embodiments of the invention, the number of current arm (1) can increase/decrease according to the slot (4) number of the motor stator and the phase/step number.

In alternative embodiments of the invention, copper, enamelled wire, aluminium and similar conductive materials can be used as conductive material. Since the current arm (1) has a movable structure on the slots (4), if it is made from conductive materials such as copper, the existing problems are eliminated after it is assembled under suitable conditions.

The magnetic field is changed by changing the number of windings on each slot (4) with the invention. Upon such change, speed-torque rate of engine changes. In addition, the system provides the speed-torque balance according to the instant need, thus increasing the engine efficiency. Since the moving mechanism (3) can change the number of windings in the slots (4), it can adjust the magnetic flux ratio as desired. As the optimum speed-torque balance can be adjusted instantaneously, it increases engine efficiency.
