What is the minimum voltage to make the motor turn? for instance would 2 rechargeable aa batteries would make it turn please? how about three?

I've just tested it down to 1.7V. It turned, but only slowly. So 2 or 3 AAs should work, even rechargables. But the higher the voltage you can use, the more speed and torque you'll get.

what is the diameter of the axle?

the diameter of shaft is 5.22 mm / 0.22 inch with 2 flats either side shaft length 8 mm hope this helps

What speed or RPM are these.?

It depends on how many volts you give them and if you fix wheels and put on a car the load will cause friction to slow them down. I tested them with no load with 5v across and they gave around 80 revolutions per minute. I used them on a car with a motor driver and found that with 4 rechargeable AA batteries around 5.2V that they were a bit underpowered so had to wire in a second small battery holder so I was using 7.8V to get them to work adequately. I have now built a second car using 8AA batteries and that works pretty well.

I’ve never done anything with electronics. What else do I need to make these run? Like wires, a battery etc, help would be appreciated :)

Not as advertised on Amazon

The motors did not come in a neat plastic box hence 4 stars. Otherwise, good value for money.

Mauvais produit

Boitier jaune n'est pas rigide, les engrenages de la réduction ont donc tendance à ne plus êtres "solidaires", même quand on fait tourner à vide. Donc fort déconseillé à moins de prévoir système de pression sur le boitier.

Very strong and affordable

These motors work incredibly as they should. Very torquey and affordable. They are ideal for teaching kids electronics, or ease of use due to the clear positive and negative leads. No soldering is needed. Would absolutely buy again
