The invention provides a control method and device of a permanent magnet synchronous motor, the permanent magnet synchronous motor and a medium, and relates to the technical field of motors. The method comprises the following steps: calculating the q-axis voltage of the permanent magnet synchronous motor; calculating the maximum amplitude of a voltage vector of a driver of the permanent magnet synchronous motor; judging whether the q-axis voltage is greater than the maximum amplitude of the voltage vector or not; if the q-axis voltage is less than or equal to the maximum amplitude of the voltage vector, determining that the permanent magnet synchronous motor is not overspeed; and if the q-axis voltage is greater than the maximum amplitude of the voltage vector, determining that the permanent magnet synchronous motor is overspeed, and controlling the driver to seal waves. Thus, the overspeed state of the permanent magnet synchronous motor is detected in real time by judging the voltage and the current, the riding safety and the riding experience are greatly improved, meanwhile, damage of the power generation state of the permanent magnet synchronous motor to a battery and a driver is effectively prevented, and the service life of the permanent magnet synchronous motor is prolonged.
