Problems solved by technology
[0002] The motor will vibrate when it is working, which will cause certain harm to the surrounding motor equipment and surrounding personnel, especially the instability of the motor during work, which will easily form a super strong vibration frequency and cause great harm to equipment and personnel. Damage, resonance caused by setting and other dangerous situations occur. The existing motor drive circuits all have the above-mentioned problems. A motor drive circuit that is more stable in operation and can maintain lower frequency vibrations is needed.
