So, if you want to modify the board, you can, and then can get your own board made at the PCB manufacturer of your choice. They were made in DesignSpark, which is also completely free to download:
#Electric autohelm 2000 motor driver
If you want to modify it, MPLab is free:Īlso, I made the PCB used for the control and driver section, and am making the schematic and pcb artwork available for you to modify to your heart's content.
#Electric autohelm 2000 motor software
I wrote the field oriented control software that goes on the dsPIC30F4011 microcontroller, and am making it freely available to do with as you please, as long as you don't make money off of it. It can be less than that if you get a few good deals on Ebay, or are content with less power.
I'm going to walk you through the process of building your own 200kW (268 HP!!) AC motor controller for around $1000. For example, a 211kW Brusa AC motor controller for use in an electic car will run you $21,000: Why is that? One big reason is that the motor controller is typically very expensive. Yet, almost all DIY electric vehicle conversions are done using a DC motor. The market is literally flooded with 3 phase industrial AC motors, so you can get them CHEAP if they are used. This also makes the brakes last almost forever! There are almost no parts that get any wear in an AC motor except for the ball bearings, which are typically very durable. You get regenerative braking for free, so that the energy you used to get your car moving can be captured and put back into your battery pack. A 3 phase AC motor is the absolute standard for car companies when they make an electric vehicle. However, they are still pretty expensive. Electric cars are the future, and are beginning to take off today.
