On Aliexpress, they sell a 410 sprocket gear with an 8mm bore and 1/2 inch pitch.

Depending on the load, torque is 0 if the load is 1 kg. 1Nt-
A PWM signal can be used to adjust the input voltage of this motor, as well as almost any other DC motor. The motor will draw whatever current (amps) it requires in proportion to the torque applied to the load. Check that the PWM controller you're using is rated for the amps you'll be using. Divide the rated motor power by the voltage to find the peak current: Watts/Volts = Amps. Because output power is proportional to input voltage using the same equation, changing input voltage will change motor speed for a given load. Expect higher amps than the motor was rated for (destruction) if you overload a motor (stall).

I haven't yet put it to the test under load. Plan on using it as a bicycle-powered generator. I expect the gear and internal bearing to take a lot of abuse. I'm not sure what these were intended to be used for. It would be fascinating to see. br>Instead of 10 mm, the shaft measures 12 mm. If you're going to remove the gear and replace it with a coupling, you'll need a 12 mm shaft. According to the specifications, the gear has 11 teeth and a 25 pitch. 8 x 1 metric thread is used for the base holes. The chain has a pitch of 25. This is a much more compact version of a bicycle chain. br>It consumes at 13 volts. 75 amps. With a light load, the amperage quickly rises. br>I'll add more as I experiment with it.
All I had to do was remove the plastic clip from the old one, then use a small flathead screwdriver to disengage and slide out the connectors. While you're at it, take a look at the black sleeve that protects the wiring. The only problem was that the motor mount had to be painted after the mounting holes were threaded. If you don't clean them out, you risk cross-contamination. threading the holes and securing the screws Use a tap/thread chaser if at all possible. If you don't have one, use a "rat tail" brush or run the screws through gently before mounting the motor. Make sure the threads aren't damaged.
This worked great for me to motorize a Fiskars reel mower. All I had to do was swap out the sprocket for one that matched the mower chain. br>br>The motor is smooth, quiet, and powerful, even when powered by an 18-volt battery.
The axle appears to be slightly out of alignment in the video. I'm not sure if it's because of my bad luck or because of a consistent quality problem. This one was returned, and a new one will be sent to confirm.
This product was supposed to be a replacement for the model that came with my scooter. There were two problems: 1. Because the mounting base was twice as thick as the original, the cover couldn't be bolted all the way down to fit properly. The length of the cables is half of what is required for connection to the controller.
It is one of my favorites. If you wanted to make a fan out of it, you could do so.
I'm still learning about the various types and sizes of chains and sprockets, so I was concerned that it wouldn't fit, but my 25 chain fits perfectly.
