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.
In short, the swinging voice coil motor utilizes the Lorentz force
generated by the coil's electrification to interact with the
magnetic field of the permanent magnet, resulting in rotational
motion. This principle enables motors to have high accuracy, high
responsiveness, and smooth motion characteristics, making them
suitable for applications that require precise control of
rotational motion.
