Swing Type Rotary Voice Coil Motor High Frequency Of Movement

The design and parameter calculation of a swinging voice coil motor is a complex process that requires consideration of multiple factors, including motor structure, magnetic field distribution, coil layout, mechanical characteristics, etc. The following are the general steps for designing and calculating the parameters of a swinging voice coil motor:
1. Requirement Analysis: Determine the application requirements of the motor, including the required rotation angle, speed range, load requirements, etc.
2. Motor Type: Choose the appropriate swinging motor type, such as torsion type, swinging type, or multi degree of freedom type, according to the application requirements.
3. Magnetic Field Analysis: Conduct magnetic field analysis to determine the distribution and intensity of the magnetic field. This can be simulated and calculated through methods such as finite element analysis (FEA).
4. Coil Design: Design the coil layout, determine the number of windings, turns, wire specifications, etc. of the coil. The design of the coil will affect the torque, response speed, and efficiency of the motor.
5. Mechanical Analysis: Conduct mechanical analysis, considering factors such as the motor's rotational inertia, load, friction, etc. to determine the required torque and dynamic characteristics.
6. Parameter calculation:
Current calculation: Calculate the required current based on the required torque and torque constant.
Resistance and inductance calculation: Calculate the resistance and inductance based on the material and geometric parameters of the coil.
Loop time constant calculation: Calculate the loop time constant to estimate the response speed based on resistance, inductance, and mechanical characteristics.
7. Feedback System: If closed-loop control is required, design appropriate sensors and feedback systems, such as encoders, Hall effect sensors, etc.
8. Control Strategy: Design appropriate control strategies to achieve the required motion and stability.
9. Thermal management: Consider the heat generated by the motor during operation and design a heat dissipation system to maintain a suitable operating temperature.
10. Simulation and Simulation: Use simulation and simulation tools such as Matlab, Simulink, etc. to verify the rationality of design parameters and optimize the design.
11.Manufacturing and Testing: Produce motor prototypes based on design parameters, conduct actual testing, and make necessary adjustments and optimizations.
It should be noted that the design and parameter calculation of a swinging voice coil motor is a complex process that requires a combination of knowledge in multiple fields such as motor engineering, electromagnetics, mechanics, etc. For complex applications, it may be necessary to use professional electromagnetic simulation software and control system design tools to assist in design and optimization.
