The invention discloses a locked rotor frequency conversion control method and device for drive motors. By means of the locked rotor frequency conversion control method and device, entry and exit of locked rotor frequency conversion are judged through the locked rotor rotating speed zone bit and the locked rotor torque zone bit, and therefore the temperature rise problem of a drive controller in the blocked rotor process is effectively solved. Thus, the time spent when a drive motor outputs large torque is prolonged as much as possible, and the load requirement is guaranteed. Meanwhile, the entry time and the exit time of locked rotor frequency conversion are staggered, the vehicle shaking problem under the critical working condition is solved, and driving safety and comfort are ensured.
