We have a old wheel chair with 2 24vdc motors on it. We are looking for a motorcontroller board that we could use to control them with arduino. I was wondering if anyone has worked on a similar project and could suggest a motor controller board(with a reasonable price tag).
Would we be better off building one from scratch? If so, can you link us to a good design?
Do you know the resistance of the motor windings? I suspect it will need controller in the region of 20 to 50A, but without more information its hard to really know - any panel or label on the motor with part number or specifications on it? 2 or 4 brushes?
Before you can purchase or build a pair of h-bridges to control these motors, you're going to need to know the current draw for the motors under load and stall conditions; do you know this (is it written on the motor? Have you measured it?). If you can post that information, then maybe we could recommend an h-bridge for you...
ok my name is Chris I’m 39 I am from the UK but i have moved to Thailand, i just got a new dog and i also have a beautiful young girl called fair she 4 years old now, here my thing i want to take my dog and my kid on the beach to play and have fun, right now i have to site on the road and which my wife and kid play, Thailand are very behind the times when it comes to wheelchairs and lets face it we are looking at around 10,000 to 15,000 for a 4x4 chair and if i imported it, how would i repair it, need that money to pay the school fees.
so can this be possible. i can get everything in Thailand is its easier to repair, but i don’t know about changing the volts can anyone help me.
