Abstract

The invention relates to the field of motor control, and discloses a motor driving circuit, which comprises a motor coil (1) and a vibration sensor (2) arranged on the shell part of the motor. The output end of a sensor circuit of the vibration sensor (2) is connected with the input end of a time domain-frequency domain conversion circuit (3); the output end of the time domain-frequency domain conversion circuit (3) is connected with the input end of a subtraction circuit (4); and the input end of the subtraction circuit (4) is connected with the output end of a preset spectrum circuit (5). The structure is stable, the operation is safe and reliable, the consumed energy is little, harms are few, heat radiation is little, aging and loss are not easy, and the spectrum energy density for motor vibration is reduced.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor drive circuit. 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 and resonance caused by setting 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. Contents of the invention [0003] The invention provides a motor drive circuit, which solves the technical problem in the prior art that it is easy to form a super strong vibration frequency and cause great damage to equipment and personnel. [0004] The purpose of the present inventio...
