The invention discloses a motor safety redundant circuit and a control method thereof, and relates to the technical field of motor control. Comprising a power supply module and a brake motor driving module connected with the power supply module through a first contactor, and provides three-phase alternating current to the brake motor module through a third contactor; the steering motor driving module is connected with the power supply module through a second contactor and supplies the three-phase alternating current to the steering motor module through a fifth contactor; the fourth contactor is bridged between the three-phase alternating current lines of the brake motor module and the steering motor module through a three-phase line; a driving program and a steering program are arranged in the main control board module, the main control board module is used for controlling the contactor through the wire harness, and the driving program is used for transmitting a brake driving signal to the brake motor driving module through the wire harness; and the steering program is used for transmitting the steering driving signal to the steering motor driving module through the wire harness. According to the embodiment of the invention, the redundancy design of the circuit is realized by adopting a plurality of contactors.
