25GA-370 DC 12V Low RPM Geared Motor Metal Gear Micro Motor for Electronic Lock Electric Curtain Actuator(5RPM)

Drop in replacement motor for a Farmlite automatic chicken door. I had to solder the wires from the old motor onto this one, but it fit perfectly. 4mm shaft, with a flat on the shaft. I got the 5rpm version. It's noticeably slower than the original. 10rpm is probably the right speed.I don't know about longevity yet, but I'm glad to have my door working again.

I create automata. Generally, I use electric gear motors. I HATE noisy motors. This little beauty is good-looking, very strong, and almost totally silent. Over time, this could become my default choice. I purchase 12 VDC motors and operate them at 5 VDC. Note: there is a corresponding reduction in speed, so plan ahead.

I used the same wire back on the dot as the old motor. When the schedule hit open it closed and close opened. Once I figure out the timing was reversed I realized was wired backwards . I just set the timing on the program and was fine.This is a solder connector so be prepared, it’s not a spade press on.

I'm using this motor to turn a custom designed ammo case loading feeder for my reloading hobby. the 5 RPM version seems to have enough torque to

I ordered the 500 RPM but receive the 400 RPM. Not a big difference but the rpm was to slow for my application

It’s quiet at low speed but gets louder as the speed increases. As others have noted it is a 4mm shaft which for me is not an issue since I was going to adapt to either.

died in 2 months of use.

Motor looks solid. I haven't used it yet. I'm building a linear stage. I bought my parts based on a 3mm diameter shaft. But they don't fit a 4mm diameter shaft.
