## Questions & Answers

**Q: How fast are the motors in mph?**
A: Miles per hour is used for measuring things with linear speed. No one would be able to answer this question for you because it's entirely dependent on what you plan on using the motors for. If you are wanting to know the linear speed of, say, a toy car that you want to put one of these motors in, then it depends on the diameter of the car's wheels and the gear ratio of the car's drivetrain.

For example, let's say you put this in a toy car that has a drivetrain with a gear ratio of 10:1. The description says the motor is capable of up to 25,000 rpm (with no load, but we'll ignore that part for simplicity's sake), so this means the car's wheels would be rotating at 2,500 rpm. Then, let's say the car's wheels have a diameter of 1 inch - this means the wheels have a circumference of  3.14 inches. So every time the wheels make one full rotation, the linear distance traveled would be 3.14 inches, and since the wheels are making 2,500 rotations per minute, this means the car would travel at 7,850 inches per minute. Convert that number into miles per hour and you get 7.43 mph. But again, that speed would only be true if the gear ratio was 10:1 AND the wheels were 1" in diameter.

However, even if your wheels and drivetrain matched that example, you would never actually reach 7.43 mph in the real world. The motor would spin slower because it would have a mechanical load applied to it, plus friction in the system and gear inefficiencies would reduce the total power output. Realistically, you might see a speed around 6 - 7 mph, depending on how heavy the car is. Theoretically, you could achieve a higher top speed by reducing the gear ratio, but this will also reduce the amount of torque the wheels are capable of producing, which means you might have a harder time leaving the starting line.

**Q: can you reverse the direction that the motor spins?**
A: Yes.

**Q: Can the motors run at a variable speed?  24000 rpm is way too fast for my application.**
A: Yes,it can run at a variable speed if you can adjust voltage lower or higher ( from 3V to 12V).Good luck!

**Q: Please advise how to wire positive and negative to the DC motor? What would happen, if positive and negative are reversed**
A: It would spin backwards.
