Globe Motors?

Why does no one use the globe motors for the drive train? What are the Pros and Cons of the Globe Motors .My thought is, if you gear the globe motors up and gear down the drill motors you would have semi-good speed and pretty good tourque. Please correct me if i am wrong. thanks

First, I will start out by saying you can do anything you want to do.

With that said, I would highly recommend against using the globes for drive motors. The main reason is they do not have the power to justify using them.

Second, by gearing up (increasing speed) you are double dipping on gear ratio. What I mean by this is that the gearbox attached to the globe motor already has a pretty big reduction, so you are “reversing” that ratio to get more speed … very ineficient.

Last, the shaft on that motor can’t take any side load so you need to add another bearing.

It is too much work for not much gain.

If you are going to pick drive motors use the Chiaphua, drill, or Fisher-Price or any combination of the three.

Plus I think that the drill and maybe others have protection that holds the smoke inside incase it stalls/overheats.

There are several reasons the Globe is not a good drive motor. First, as was stated above, the motor was designed for axial torque, which means that it doesn’t handle side-load well. Second the globes aren’t as strong as the other motors. The bosche, FP, and Atwoods are all considerably stronger than the Globe. Lastly the Globe has a very limited range output. It is very close to having just two speeds, on and off. The other motors utilize a wider range in output speeds.
