    • The motor control circuit (16), which is the subject of the present invention is used to control brushless type direct current motors (1). The subject motor control circuit (16) comprises a rotor position identification circuit (4) which takes as input voltage signals at phases of the brushless direct current motor (1) and instant speed data of the same and which generates commutation signal serving to determine which phase of the brushless direct current motor (1) to enter into operation ( commutation points) in the next step, a control circuit (3) which determines switching signal (A1, A2..., An) to the transmission/cut instants of switches feeding brushless direct current motor (1) phases using commutation signals and a power switching circuit (2) which puts switches feeding phases of brushless direct current motors (1) in transmission/cut off using switching signals received by control circuit (3). While rotor position identification circuit (4) serving to determine rotor position receives commutation signals which determine which phase to follow it is ascertained that brushless direct current motor (1) operates at desired performance even at speeds which differ by ensuring operation at correct instants of brushless direct current motors (1) using motor instant speed data.

    • The object of the present invention is to obtain a high performance and low-cost electric motor that simplifies the transfer of the mechanical motion created by the motor to the driven load, requiring none or some mechanical transfer means such as belt/pulley arrangement or a gear box, on applications especially requiring varying torque and speed operations, requiring wide torque-speed range; requiring high torque value at low speeds. In the motor subject to the present invention, which has a structure with external rotor, the stator and rotor are formed by the packaging of magnetic lamination segments that are cut in 180 DEG or smaller angles in order to complete 360 DEG . The rotor yoke (2) of said motor on the inner surface of which a series of permanent magnets (3) are placed with no spaced apart intervals and said permanent magnets (3) are connected with the motor shaft (7) by the rotor body (1) and rotor hub which are made of non-polymeric or non-magnetic metal suitable for injection casting, or directly with the load shaft.
