To save me from a lot of headache, can someone send me the DCF file for this motor to be run with a Sevcon gen4 (size 2)controller?

So how much did it cost with shipping and VAT?
bionicon said:i am running the motor now for a few months with a sabvoton 72150 unlocked at 58 volts on my derbi senda.
Settings are 200 batteryamps 450 faseamps, we make hard drives in the woods for 3 hours every week with no problem so far
Maybe i will change to 84volts for more power

larsb said:What is your wheel size and reduction ratio?
I run 17" wheels and 1:4 to the rear wheel. Power wheelies is the goal but right now my moped does 90 km/h so it's not very strong

This design is called IPM.
Instead of placing the magnets on the surface, steel laminations are used to direct the magnetic flux to the stator.
As it happens inside the stator steel there can be also eddy currents in the magnets, which means the magnets will become hot just if they pass the stator teeth, and this IPM design schould reduce the eddy currents in the rotor to a minimum (lower no-load losses and higher usable RPM).
So basically what spinningmagnets said, just bit more detailed explained.
