You can change the turbine(I think that's the proper terminology; @"Ucwepn" might know more) within the motor to enhance either speed or pulling power, or even both! Each Plarail engine is different, with some having 2-Speed motors (Default and faster), Hi-Power motors (faster, but stronger; takes a bit more to make the gears skip), and things of the nature.
I think you mean the rotor, but to be honest although it is possible to change the rotor in a Motor, it is much easier to just to change the entire motor for something which has more power, I think ucwepn uses the hyperdash2 motor with a lot of success

I've used this motor and it's nice to use, a good allrounder which is faster than the original, and is a direct replacement, for the standard item,
