As shown in the figure, u1 is an ac-dc power supply module. The current problem is that fuse f1 sometimes burns out. Is there any way to solve it, the normal working current is only a few hundred mA.

Is it burned after use? Is the motor followed?

The next one is the motor, which was burned out when the power was turned on.

Measure the current at the moment of power-on. Is the slow tube or fast tube used for the fuse?

At present, it is a bit difficult for the company to measure the power-on current. The fuse is an ordinary glass tube, and it should be a fast melting.

Change the slow tube, count 3-5 times the current when the motor starts, and reselect the fuse.
