Not a huge amount.... IGBT's have come a long way. And the problem with your situation, is that between them and Kelly, they're the only ones that make a 120VDC BLDC motor controller that is commercially available. And I won't recommend Kelly.
Not sure about price, you should contact one of their distributors.
sevcon is a great company with good quality and the performance on the controllers I've seen is good. These are their new line.
Thanks for reply.
I will write inquiry to Sevcon.
Maybe someone else have found other manufacturer.
I have also found Sigmadrive controllers http://www.dmcde.de
But they limit max. to 120V battery supply

It is slightly overvoltaged perm motor. nominal voltage 96V.
Due different battery configuration the nominal voltage will be 115-120V.
Motor is rated at 16kW nominal S1, peak 2.2 x 16kW ~35kW
Hmm...
I have to say, it is the reason I did not buy that controller. It was not clear for me why they wanted 900$ for pure usb>can programmer ... now I know. The dealer didn't tell me that this is package of software and programmer kit. I was totally sure that software/programming support was included in controller price.
Over all, it seems to be cheaper to develop my own controller and sell kit version in future.
so does that mean that using the hand-held programmer a sevcon controller can be paired to an AC motor relatively easy??? if that is the case, it seems reasonable that controller dealers would rent the programmer to their customers, or people planning to use a sevcon would chip in and only buy one programmer...but that's only if the hand-held programmer makes matters easier which I am not sure if it is the case.
It's a bit like the Curtis AC controllers. They need a programmer to set them up for the motor and current limits, battery voltage, etc. Many places that sell the controllers will rent a programmer to you. I know ElectricMotorsport and Thunderstruck do.
It was first controller I have considered to buy.
Unfortunately there is no available version for higher voltage for PMS motor (max battery voltage in my system is 135V).
These controllers only work with 12bit encoders (I have 8bit)
Second link - sigma2 is not available - coming soon as stated on website.
PMSM is easier to control than ACIM because of the ease of finding the rotor flux angle. It's just the same as the rotor angle. I'm 99% done with some FOC software for a PMSM motor, and have some boards on the way. There's a power board (4 ounce copper), low side driver, high side driver, and then 4 layer control board. It's all open source so once it gets posted to the ecomodder wiki you can decide if you want to go that route. It uses 24 TO-247 (or t-max) package igbts, and through-hole film caps. Rated to around 330v DC bus, and maybe 200ampRMS per phase. We'll see though. Assuming a PMSM motor, that works out to
power = Vrms * Irms * Sqrt(3) * power_factor
Power = 330/sqrt(2) * 200amp * sqrt(3) * 0.95
Power = 77kW
There's really not much to drill, and the parts cost is around $500 or so I think. I"ll have to add it up, but it should be pretty cheap.
i.e. I found an infinion hybrid car kit1, semicron skai, etc... the question is if you can get your hands on them. But again you might contact the respective student team, they can help your further!
Sevcon now has a sales department to deal with private customers like us, contact is : Glyn Martin Managing Director Sevcon distributer uk south Aviation Equipment Resources Ltd Office 53 , Airways House 1st Avenue , Stansted Airport , Essex , U.k.
Glyn Martin just told me that they are only picking up business now and start after easter! Just got a quote for the Gen4 size 8 controller = 7.012 Euro! + VAT
I found out, that the 2 controllers I posted before are more or less identical!
DMC / The German trader of pg-drives sigma ("sigmadrive") sort of sold the product development of their own pro-range to pg-drives and they will lauch them now as "Sigma 2"!
Now what I came upto:
obviously all the high-voltage systems do cost !
I have following price quotes so far respectively (not yet Piktronik - but I guess they can´t do magic-prices either!):
Unitek Bamocar D3 for Eur 3.400,-only sold to OEM, from Turn-E (Munich) Eur 4.400,-
tritium wavesculptor200 for Eur 4.700,- (AU$ 6.000) NO CE-Mark!
EVE quantum330 for Eur 5.900,-
Paragon MoDrive40 for ca. Eur 7.000,-
Sevcon Gen4 size 8 for ca. Eur 7.000,-
Mes Dea Tim 600 for ca. Eur 7.000,-
Rinehart PM100DX for Eur 7.200,- (US$9.500)
Brusa DMC 524 AC Eur 19.200,- !
all prices excluding taxes & shipping
I haven`t heard of anybody to succeed in getting an Unitek Bamocar D3 yet, except for student race teams though!
All the others fall (more or less) in the same price range, except for the Wavesculptor200 - but TÜV, etc might be complicated and cost intensive (EMV) here, as I know from people who used it!
Better try to get a Bamocar D3, if you can get your hands on it!
