What is the technical principle of a swinging voice coil motor?

The Swing Mode Rotary Voice Coil Motor is a special type of motor that utilizes the interaction of current and magnetic field to achieve rotational motion. Its technical principle is based on Lorentz force and Faraday electromagnetic induction principle. The following is the technical principle of a swinging voice coil motor:
1. Magnetic Field and Coil: The core of a swing type voice coil motor is a circular coil that is fixed to the motor frame. A circular coil is a conductor of electric current that generates a magnetic field by applying electricity.
2. Permanent magnet: Place a permanent magnet (usually strong magnetic) around the circular coil. A permanent magnet generates a constant magnetic field that interacts with the current passing through the coil.
3. Lorentz force: When current passes through a circular coil, the current inside the coil will interact with the magnetic field generated by the permanent magnet, generating Lorentz force. Lorentz force is a force perpendicular to the direction of the current and magnetic field, and the direction of the force can be determined according to the left-hand rule.
4. Torque generation: Due to the Lorentz force, the circular coil begins to rotate. The Lorentz force causes the coil to experience a torque in the magnetic field, causing the coil to rotate.
5. Motion Control: By adjusting the current and direction through the coil, the speed and direction of the swing type voice coil motor can be controlled. The change in current will cause a change in Lorentz force, thereby adjusting the rotational speed of the motor.
6. Feedback System: In order to achieve closed-loop control, position or angle sensors (such as encoders) can be integrated into the motor to monitor the actual movement of the motor in real-time and provide feedback control.
