A soft start-up system for a motor that minimizes formation of surge and effectively contains its impacts upon any other source voltage in the peripheral to further promote safe power consumption is mounted on a motor source circuit and includes a power resistance and a relay; the power resistance is electrically connected in series to the motor; and the relay is connected in parallel with the motor and has a contact connected in parallel with the power resistance. Upon starting up of the motor, a drop generated at a working point to create delayed LV soft start-up for the motor under the condition of the activation point of the relay is OFF; and once the motor is started up, amperage drops and the relay is triggered off by returning to a working voltage connected in parallel to the relay, source at the working contact is conducted ON for the motor to resume its normal operation status.
