As a company, we want to produce a DC 5V submersible water pump. I dismantled a few DC 5V water pumps that I purchased and examined their internal structure. They all have the same 4-legged (TO-94) component. It looks similar to a hall-effect sensor, but it’s a different component. Can you help me find where I can purchase this component?"
I believe devices of the type found here would be what you’re looking for.
thanks for your effort.
I used chips similar to the ones here (us91a, sdc1576) but the problem is; If I do not give the first movement to the motor shaft with my hand, the motor does not start. When I move the motor shaft with my hand, the motor starts to run.
When I assemble the chips from the pumps I bought and disassembled into my own engine, the engine starts to run as soon as I give the energy. I do not need to give the first movement to the motor shaft with my hand.
note1: i plan to put the chip in this pump.
note2: chips from inside pumps I bought and smashed.

I am unable to identify the manufacturer of either of the devices pictured.
Differences in the position of the hall sensor within the device might explain the difficulty in starting, but motors of this type have low starting torque as a general rule.
