Yeah the Lectra use to use them (an electric motorcycle). I don't know about the efficiency though, I wasn't impressed with the numbers I saw for it.
As I recall they also have a problem with cogging unless you spin them really fast...in which case you need a high ratio reduction (transmission). The weight and expense of the motor/transmission combo eliminated most of the advantages. I think you would be better off using an E-tek motor and suitable controller (cheaper, same or better efficiency, smaller and lighter, possibly more powerful). I'm not sure about the more powerful though, NEDRA lists one or two records using modified Lectra motor/controllers in cycles and gocart(s). > Hi EVers > > I've been reading a little about Switched Reluctance motors and I was > wondering if anyone is using one in an EV?
