Abstract

The present invention discloses a novel DC motor characterized in that magnetic field lines of a magnetic field are used to strictly follow the same single direction magnetic flux across the interface air gap between the rotor and the stator, so that most of the armature coils move during the motor movement. The electromotive force of the same polarity and the force of the same direction are always received. Therefore, when the armature coils are connected, the electromagnetic polarity reversal is not required, and the electromechanical bidirectional energy conversion can still be continuously generated, and the armature is collected sufficiently large. The electromotive force is induced to adapt to the proportional relationship between the motor terminal voltage and the speed or the moving speed.

Description

DC motor

The present invention relates to a DC motor, and more particularly to a DC motor without commutator.

The conventional DC motor (Dynamic Motor) is equipped with a commutator (commutator) structure to maintain the rotor magnetic field and the stator magnetic field in a direction orthogonal to the maximum torque at any time during the rotation. At the same time, the DC motor maintains a voltage proportional to the simple nature of the speed, and the control is natural and simple, which has always played an important role in the traditional speed control, servo control and other fields. The BLDC Motor-Dynamo, which is popular in the market today, is similar in structure to a permanent magnet type variable frequency synchronous rotating machine. It mainly uses multi-phase magnetic field angles to alternately grow and combine to form a rotatable angle. For example, the angles are 120. The three-phase magnetic field, the rotating magnetic field of variable speed drives the permanent magnet rotor, or the electromotive force induced by the rotating permanent magnet rotor is induced to extract AC power through the multi-phase coil. Although this method is mature, its VVVF control method is quite complicated and unnatural. Therefore, we seek a non-commutated DC motor with simple electromechanical structure, simple driving mode and better control performance than traditional DC motors.

In view of this, the present invention discloses a novel DC motor characterized in that the magnetic field lines of the magnetic field are mostly used in the same single direction magnetic flux across the interface air gap between the rotor and the stator, so that most of the armature coils are During the movement of the motor, the electromotive force of the same polarity and the force of the same direction are always received. Therefore, when the armature coils are connected, the electromagnetic polarity reversal is not required, and the force is still generated continuously. Electromechanical two-way energy conversion, while collecting a large enough armature induced electromotive force, in order to adapt to the proportional relationship between the motor terminal voltage and its speed or moving speed.
