The invention discloses a two-for-many redundant soft-starting system for a motor. A conventional power network of the system is connected with a first quick fuse and a second quick fuse through a first circuit breaker and a second circuit breaker respectively; the first and second quick fuses are connected with a first soft starter and a second soft starter respectively; the outgoing line terminals of the first and second soft starters are connected in parallel to form a soft-starting power network which is connected with a plurality of motors; a soft-starting contactor is connected between each motor and the soft-starting power network; the conventional power network is connected between each motor and each soft-starting contactor through a bypass contactor; the first soft starter, the second soft starter, each soft-starting contactor and each bypass contactor are connected with a controller respectively. According to the two-for-many redundant soft-starting system, the reliability and continuous operation performance of a production control system are improved greatly, moreover, the service life of the soft starters is prolonged, and the maintainability of the soft starting system is improved.
