The application relates to the technical field of starting motors, and particularly discloses a fan heat dissipation type starting motor for a
centrifugal pump, which comprises a base and a
machine shell fixedly connected to the base, a strip-shaped air inlet is arranged on the
machine shell and penetrates through the inside and outside of the
machine shell, a filter screen for shielding dust is arranged in the strip-shaped air inlet, a rotor is arranged in the machine shell, and a transmission shaft penetrates through the rotor coaxially. At the beginning of starting, the
fan blade cannot rotate at high speed, so that the starting response slow degree and the starting current size of the
centrifugal pump can be reduced, the additional
energy consumption loss of the motor at the initial stage of starting can be reduced, the windward area of the
fan blade at the initial stage of starting of the starting motor is small, so that the rotating resistance of the
fan blade can be reduced, the starting response slow degree and the starting current size of the
centrifugal pump can be further reduced, and the additional
energy consumption loss of the motor at the initial stage of starting can be further reduced.
