The invention relates to a motor control overmodulation method and system, electronic equipment and a storage medium. The overmodulation method comprises the following steps: calculating action time T1 and T2 of two adjacent voltage vectors in each sector based on an SVPWM (Space Vector Pulse Width Modulation) control method; judging whether the sum of T1 and T2 is not less than the current carrier period Ts, and if so, modifying the values of T1 and T2 based on the value of the current carrier period Ts; a non-overmodulation area and an overmodulation area are unified, software codes are easy to implement, the engineering effect is obvious, and the utilization rate of the bus voltage is increased; the utilization rate of the bus voltage is effectively improved; the technical problems that in the prior art, an overmodulation method is complex in implementation process, time-consuming in calculation and large in occupied program space are solved. The utilization rate of the bus voltage is effectively improved; the technical problems that in the prior art, an overmodulation method is complex in implementation process, time-consuming in calculation and large in occupied program space are solved. Linear modulation and overmodulation are in smooth transition; and the stability and the response speed of the system over-modulation region are improved.
