The wheel in question is hooked directly to the motor shaft.
Sorry this is a noob question.

A wheelchair motor runs on DC (direct current), thus one pole is positive, the other is negative. The rpm is limited by the governator and/or the load. By removing the governator the rpm no longer limited. Now you have to increase the power per rotation. This is done by raising the Voltage. So you have to connect another battery in series with the other one. Connecting a variabel resistor is reccomended if it doesn't already have one (throttle), because the motor can burn trough by the generated extra heat.

You can buy a speed controller which controls the amount of volts and/or amps going to the motor, thus the speed can be varied. Installation may be difficult as far as mounting and wiring.
There are probably other electronics you will need to rip out because the wheelchair may have a failsafe for limiting motor voltage.

The speed of the permanent magnet motors used in these devices is proportional to voltage delivered to it. If the battery voltage is 12 volts than the motor uses 12 volts to get top speed. Adding a few more volts will get proportionately more speed but can damage support electronics.

each and every resistors and transformers will define the acceptable rigidity velocity of a motor. To the equation of FD = r * V the place: FD = a made up value for the rpm of the motor shaft. R = resistance (usual) V = Voltage (user-friendly) The motor is spinning at a p.c.. based on the over all "energy" (watts) it gets/makes use of. it's going to prefer to "use" all energy handy, to an volume. to regulate the a million.5V fan, firstly be sure you would be effectively providing a million.5V, then upload a variable resistor to the circuit (calculate which values you like, and purchase it from an electronics shop, ones with Dials are pronounced as Potentiometers, or "Pots"), this provides you with a dial to alter the resistance, hence slowing down or dashing up the motor. you may additionally upload a fuse to the circuit for a undeniable Wattage, desperate with the aid of utilising the max energy you prefer to have the motor to apply. If the motor burns out, it cut back down it performance and easily desire extra capability to spin on the trouble-free rpm, which with blow the fuse if effectively calculated. Capacitors are not extreme, notwithstanding a diode is had to transform to DC, yet your transformer will would desire to try this for you. stable fulfillment with the 'lectrics.

Increasing the voltage to the motor will increase the speed. So maybe two batteries instead of one. If there is a controller two batteries may damage it, so be careful.

The cheapest would be to remove the governor on the motor if there is one.

Ooh - great question! Sorry I don't have an answer for you... it's not gas powered so nitrous oxide won't help. Good luck!

You would need a super-charger!
