The invention discloses a double-motor driving structure of a double-rotor type compressor and a control method of the double-motor driving structure. The double-motor driving structure comprises twomotors which are correspondingly connected with two compressor rotors through couplers, the two motors are connected with a power supply, and the speed ratio of the two motors is controllable. The control method is divided into three control schemes according to the speed ratio control precision requirement of the compressor rotors, and the control method comprises the two motors directly connected with one power supply, wherein one motor is connected with the power supply through a frequency converter, and the two motors are correspondingly connected with the power supply through the frequency converter; and the frequency converter is provided with a controller, and the controller is used for analyzing the difference value between the speed ratio of two rotation speed sensors and the setspeed ratio; and the set frequency of the frequency converter is adjusted, the rotating speed of the motors connected with the frequency converter is controlled, and the constant speed ratio of the two motors is kept. According to the double-motor driving structure of the double-rotor type compressor and the control method of the double-motor driving structure, the normal operation of the rotor type compressor is ensured, synchronous gears required by a traditional structure is omitted, so that the problem of oil leakage is avoided, and the double-motor driving structure is symmetrical and hasthe effects of reducing noise and the like.
