I've built an electric moped by replacing the ICE with a Turnigy 80-100 on an old Puch Maxi.
The motor is fitted with SS411A hall sensors and rewinded with double strands of 1.5 mm copper wire for 90 rpm/V. I use a Lyen 12 x IRFB3077 controller to run it from 12s2p Turnigy 5 Ah 20C batteries. The motor drives the 17" rear wheel with a 10/43 chain reduction. When I first got the controller it was set to 40 A battery current limit which resultet in a pretty slow and weak moped. I reprogrammed it for 65 A (160 A phase) instead and the moped was extremely nice to drive. I was playing around in with this configuration for 20-30 km during a couple of days, and it worked perfect. I made a GPS log to get some figures of the top-speed and acceleration. The log was recorded back and forth and the peak difference in speed depends on some pretty strong headwind.
Top speed 68.9 km/h (43 mph) and a lot of torque.
For some more info about the build, my project blog.
Now to the question:
After several hard accelerations in a short period of time I managed to cook the motor, How much current are you reliably putting through the Turnigy 80-100?
