Custom Controller Vendor Search

Custom Controller Vendor Search

Custom Controller Vendor Search

(OP)
Hello, I'm looking for an automotive brushless dc motor controller vendor. The controller will be less than 1kw, operate a small motor at 20,000 rpm. The controller will operate at up to 450 VDC. Operate on hall sensor feedback. Must have CAN control capability. The vendor must be capable of supplying units in prototype quantities. I am interested in any/all leads. Thanks.

Your location?  The people I know are in NW New York.

I am located in Tempe, AZ. However, I am willing to look at all domestic suppliers. -SK

Look at Elmo controller with build-in servo amp (www.elmomc.com) - HARmonica series. This amp has CAN and allows to operate with Halls.
Do you have automotive application with up to 450VDC supply really?

RE: Custom Controller Vendor Search

blacksea, my Q exactly, not only that up to 1kW and 20KRPM?

Anyway, you could also try Industrial Indexing Systems, in Victor, NY.  (iis-servo.com)  

My experience with Halls has been somewhat disappointing; resolvers supply better data for the brushless DC apps I have seen.

RE: Custom Controller Vendor Search

One question before I make a recomendation;  what is the anticipated production quantities following the prototype stage?

RE: Custom Controller Vendor Search

(OP)
Thanks for the feedback so far. Here is some additional information ... The controller will drive a fuel cell system component. Prototype quantities will be several hundred units.  Hall sensors are adequate for speed control in this application. 1 kW and 20 Krpm are real. I'm not interested in servo-type controllers. I simply need speed control.  Production quantities will depend on the success of fuel-cell cost reduction success. There will not be significant quantities for at least 5 years, if at all. Anticapated quantity over next 2-3 years is several hundred. A smaller company that that can customize an existing automotive controller design would the ideal fit for this application. Thanks again. -SDK
