Linear Motor Transient Waveform Tuning by Resonant Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear motors of different types or with different resonant frequencies require distinct transient driving waveforms, leading to inefficiencies as existing vibration description files cannot adapt to individual resonant frequencies, resulting in suboptimal vibration effects.
Innovation Solution
An adjustment method and apparatus that generate a driving waveform by recognizing the resonant frequency of a linear motor and combining or selecting half-cycle waveforms to create a transient waveform that matches the motor's resonant frequency, ensuring the waveform type in the vibration description file is adapted to the motor's specific frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different transient waveforms are used for linear motors with different resonant frequencies, then the vibration effect is optimized, but the device complexity increases
Solution Approach 1:
The patent creates a universal transient waveform file that can be applied to all linear motors regardless of their resonant frequency. The waveform file contains frequency-independent control parameters that work across different motor types, eliminating the need for separate waveform files for each motor variant.
Solution Approach 2:
The patent separates the resonant frequency parameter from the waveform structure itself. Instead of creating different waveforms for different frequencies, the system uses a single waveform template where only the frequency parameter needs to be adjusted, while maintaining the same transient waveform characteristics.
2Measurement precision
If separate transient waveform files are created for each linear motor type and resonant frequency, then the driving precision is improved, but the maintenance difficulty increases
Solution Approach 1:
A single universal transient waveform file serves all linear motor types and resonant frequencies, eliminating the need to maintain multiple separate waveform files. This reduces maintenance burden while preserving driving precision through parameter adaptation.
Solution Approach 2:
The system uses a master template waveform that can be copied and adapted to different motors by adjusting the frequency parameter, rather than creating and maintaining separate original waveform files for each motor variant.
3Adaptability or versatility
If multiple transient waveform files are stored for different resonant frequencies, then the adaptability is improved, but the storage requirement increases
Solution Approach 1:
One universal transient waveform file replaces multiple frequency-specific waveform files, reducing storage requirements while maintaining adaptability to different resonant frequencies through parameter adjustment rather than file multiplication.

AI summary
Embodiments of this application provide an adjustment method and apparatus for a driving waveform, a device, and a storage medium. In the adjustment method for a driving waveform, a vibration description file is obtained; a waveform type described in the vibration description file is recognized; and a driving waveform of a linear motor is generated according to a vibration parameter described in the vibration description file and a resonant frequency of the linear motor in response to recognizing that the waveform type described in the vibration description file is a transient waveform. In this case, it can be seen that the driving waveform of the linear motor is generated according to the vibration parameter described in the vibration description file and the resonant frequency of the linear motor in a case that the waveform type described in the vibration description file is the transient waveform.
