What options are there for controllers for a brushless Etek? I have seen the specs for the Sevcon one but I haven't seen where I can get one to run the full 48 volts. Who else makes one?
I am also (just kill me now) pondering the idea of starting an open source project to make one. I have developed DSP firmware for this type of motor before using the TI 2812 series chips but on a much smaller scale where the motor was about the size of half a beer can and drew 1 amp max. So I am aware of the issues involved and also that handling 300-400 amps might involve some challenges on its own. I will probably see reality again soon but if there is someone similarly motivated with the EE skilz to complement mine in the power control area we could try to get this going. jv -- Blog: http://volcano.newts.org
