The invention discloses an integrated variable frequency motor, which comprises a main inversion circuit and a motor, wherein the motor comprise multiple groups of independent three-phase windings; the three-phase windings in different groups are isolated electrically; the main inversion circuit comprises three-phase inverse circuits of which quantity is the same as that of the three-phase windings in the motor; the output end of each three-phase inversion circuit is connected with one group of three-phase windings; the direct-current input ends of the three-phase reversion circuits are connected in series, and bear the total direct-current bus voltage of the main reversion circuit together. According to the integrated variable frequency motor disclosed by the invention, the quantity of power semiconductor devices in the three-phase inversion circuits is small, and low-voltage-resistance power semiconductor devices can be adopted; moreover, application requirements can be met without connecting the devices in series, so that the problem of inherent voltage sharing in serial devices is solved completely; meanwhile, the output voltages of the three-phase inversion circuits are lower, and dv/dt is smaller, so that an output filter can be eliminated, the cost is reduced, and the equipment size is reduced.
