Homemade 100 HP Motor Controller for an Electric Car
200kW AC Motor Controller for Electric Car
Great project, thanks for sharing!
Hi, I think this is a great project. Thank you for sharing. Is this for brushed or brushless?
This is a 200KW speed-controlling inverter. That is about 268HP with the right motor and batteries! For a wheel-chair 2KW/2.68HP would be more than enough and you wouldn't need the "Regenative braking" either so you could happily go for DC motors. There are lots of off-the-shelf solutions for low powered stuff. What makes MPaulHolmes project great is that now there is a feasible solution for converting a car to electric where before it was cost prohibitive.
Paul,Awesome job on the controller. I am very interested in your instructable. My DIY EV car has a DC motor (no regen) and operates at 120 Volts off a modified Chevy Volt battery. It has dismal low end torque (0-60 in 30 seconds!!!) and have been looking at AC as a possible fix. I want to try your controller but I don't see the PCB and components listed. Is it possible to buy that component from you?
can I pay you to make one for me for 400kw 360v
Cheers Paul to an impressive project.Do you have a spec for the maximum rpm the design can realize?It is probably dependant on the PIC-capabilities and I need much more than the 200 rpm asked for above.
Do you have one for sale?
Hi, I would like to make controller like that one but i can't see anyhing from the pictures above. Do you have scheme or better quality pictures of this control board?
hello , I would buy this controller or the board , to my kart, paraens to work you have fans in Brazil . v8artesanalgmail.com
I'm curious because those half-bridges are so expensive, could you build the half-bridges out of individual IGBTs like this one: http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FGPF4633TU/?qs=sGAEpiMZZMv4z0HnGdrLjg2lSZBYbkWPL4w9lb0h0yc%3d . So you would theoretically 6 IGBTs to make three half-bridges right? I'm asking because it would drastically reduce the total cost if this were the case.
Hi guys! I Found this Website, it has a detailed PDF and they are selling the boards as well.http://www.paulandsabrinasevstuff.com/evmotorcontrollers.html
What actually limits the controller to 400v? Both the igbts you linked are 600vdc max. What else is limiting the max voltage?
Pretty amazing pdf.
Hello, this controller looks great. But I have a couple questions as I haven't had the time to go through thoroughly. I am working on a similar project myself. the only main difference is that I am working with a 12 pole motor of my own design. and am going with Beefier IGBTs as I plan to go as high as 600v-750v and higher amperage. Also, I am trying to do without an encoder as my motor has a 6" hollow shaft, and I have yet to find one to fit. And latter work on connecting 2 or more of these controllers together to control multiple motors. I was wondering if you were able to build in Regen? I am trying to figure the best way to make it variable. so that the harder the brake is applied the more regen is fed back to the batteries. And of course if it goes out of limits to dump the rest via resistor. Also I am trying to figure out how to add a reverse switch. So that just as in a regular car you can have a drive position and accelerate with the throttle. Use the regen braking to stop, "shift" to reverse and use the same throttle control to accelerate in reverse. And of course I would probably add a limit to the max reverse speed.
Hi there... Love this projeckt Where can i get bill of material for pc board and the layout ?
Hi i am wery interested in this projeckt where can i find partslist for the Control/Driver board and the motherboard for that ? (plate)
I would like to see those files too :) I was searching through many many forums, old posts and blogs, but sadly not really much. :/
