The invention discloses a motor power supply with soft starting and overcurrent protection functions. The motor power supply comprises a power supplying part circuit, a starting protection time-delaycircuit, a current detection circuit, a protection control circuit and a motor. The power supplying part circuit is connected with the starting protection time-delay circuit, the current detection circuit, the protection control circuit and the motor. The starting protection time-delay circuit is connected with the current detection circuit. The current detection circuit is further connected withthe protection control circuit. The protection control circuit is further connected with the motor. The motor power supply with the soft starting and overcurrent protection functions has the double-power-supply function so as to meet continuous operation of the motor, and the overcurrent protection function of the direct-current motor is achieved by utilizing a logic gate controller to be combinedwith a relay; and meanwhile, the anti-interference function is further achieved, and therefore the advantages of stable performance, convenient use and good protection effect are achieved.
