The utility model discloses an asymmetric cooperative control three-phase balance motor soft starter, comprising a three-phase AC power supply input end, a power adjusting unit, an output end connected to a three-phase asynchronous motor, and a main controller which are connected in sequence. The power adjusting unit comprises an A-phase control module which is internally provided with a first thyristor at least controlled by a main controller; the B-phase control module is internally provided with a pair of antiparallel second thyristors controlled by the main controller; and the C-phase control module is internally provided with a pair of third thyristors which are controlled by the main controller and are reversely connected in parallel. The main controller cooperatively controls the conduction angles of the first thyristor, the second thyristor pair and the third thyristor pair in the starting process of the motor by outputting a control signal so as to adjust the voltage applied to the motor and improve the balance of the three-phase output voltage. According to the utility model, the three phases are controlled, so that the three-phase balance during starting is effectively improved, and the vibration and noise of the motor are reduced.
