Accurate Motor for Wheelchair?

Hello, teammates!
I have been in search of accurate motors that can be compatible with Arduino and can withstand the person weight. Can anyone suggest me which motor shall I be using?
Thank you!

Well, this is valid for prototype but not actual wheelchair!

I mean it’s capacity is not that high and can’t be compatible with heavy motor and high torque motors.

Shrey Fadia I can understand the confusion you might be going through

The two basic things here are motor and gearbox
( there are lot of things to be considered while selecting ,but I’ll try to simplify ,So that you can collaborate well with mechanical engineers

Motor usually runs on high rpm ,but for a wheel chair we do not need high rpm ie you don’t want the wheel chair to move fast

So the gearbox reduces the speed and gives your wheelchair a safe speed
Gearbox also does the work of increasing torque

And high torque is needed to increase it’s load carrying capacity

We can say torque and speed are inversely proportional

So basically what you want to keep in mind is you need less speed and more torque for which you need a gearbox

There are various type if gearbox you need to look into that
In which planetary is one ,but I wouldn’t recommend you planetary because of their high cost and it’s not needed in this application

You need to define the reduction ratio before selecting gearbox

You might have to go through some research papers
