how to speed up my robots drive
Hi guys
At the last event Steve suggested I swap out Judge Mentals 24v scooter motors with 12 volt scooter motors to get a bit more speed .....But Because I have a pile of 24v scooter motors , Im thinking is there a way of turning them into 12v motors(by cutting some wires or something?? I'm running them on 6cell 22v so they are running a bit under speed anyway. Running on hacked tz85s I think they are maxed at 6cells.

You cannot easily alter a motor to spin faster on the same voltage - the motor armature would have to be completely re-wound. The classic ways to get more speed are:
Increase the voltage (also increases pushing power & motor heat)
Decrease the gearing between the motor & wheel
increase the wheel size (another form of gearing)
Change the motor for a lower voltage model
Of course, you can combine any of these to get the result you want. As you are limited to 6 cells, I would look at the gearing options first.

Righto will just have to buy some of those 12v motors from oatly electronics.
Yeh you really need more power move to 12V scooter motors I think. Changing the gear ratio might help but will reduce its pushing power. Not sure if that is an issue currently.
