Description
technical field [0001] The invention relates to the technical field of motor drivers, in particular to a low-vibration motor driver structure. Background technique [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. Dangerous situations such as damage, resonance caused by installation, etc., all existing motor drivers have the above-mentioned problems, and a motor driver that is more stable in operation and can maintain lower frequency vibration is needed. Contents of the invention [0003] An object of the present invention is to provide a low-vibration motor driver with stable operation, low energy consumption and high safety. [0004] The above-mentioned technical purpose of the present invention is achieved by the follow...
