Hello
Well I finally got the first of the Pumas tested! using the BMX as my trusty test machine I have attached the new controller alongside the existing xlyte controller, I removed the BMX wheel and swapped the motor innards for the first of the new Pumas.
These new motors are made by the same factory as the BMX ones, so they have the nice durable gear in the wheel and decent quality winds and build.
The first motor tested in the batch is the 500W 250 RPM motor, all the new motors come fitted with Xltye controller connections and Puma motor connections, this makes it easy for me as I want to test the new motors on the Puma controller and the Xlyte controller.
The 1st motor combo was the 500W 250 RPM, the factory have beefed up the phase wires on these motors and the overall quality is very good, they still insist of thread locking the covers on grrrr this is a pain as there is always one screw that wont budge, I had to drill one of them out in order to free the drive mechanism.
I got it all swapped over and fitted the torque arm, by the way the stock stainless torque arm takes a real battering when running a 20 inch wheel, its just about ok, any more power and I would run 2 of them on each side or get a thicker one made.
Here are the Test results
I did a fixed circuit both times and used the GPS to compare both runs alongside the Watts up to gauge the Amps used and power consumed.
500W - 250 RPM Puma connected to The new 36-72V 35A Puma (silver controller) BMX - 20 Inch wheel. Tested at 37V (LIPO).
17mph on the flat, good hard acceleration with a lot of torque, motor running very smooth and quiet.
1.2KW Peak power at 34.6A.
500W - 250 RPM Puma connected to The Xlyte 36-72V 35A (Black controller) BMX - 20 Inch wheel. Tested at 37V (LIPO).
18-19mph on the flat, good hard acceleration, slightly less torque than when connected to the New Puma controller, and a little more lumpy.
1.25KW Peak Power at 35A.
I also found that the old Puma phase colour match isnt the same, when I tried to connect the new Puma to the Xlyte controller ALA the BMX it didn't work, I had to swap the phases around and hit the reverse on the controller in order to get it to spin properly, see below.
New Puma Front 500W - 250 RPM connections to Xlyte controller.
Phases - Controller to Motor.
Yellow - Blue
Blue - Green
Green - Yellow.
Hall colours were a direct match, the no load amps in both cases was about 2.1A or so which seems normal.
So these new motors are looking pretty good, I will have a play with the phase combinations to see if some work better than others, they look ok though, the new Puma controller seems very nice indeed, it certainly runs the motor smoother than the Xlyte but they are very similar in performance terms, it remains to be seen how reliable it is at 72V that will come in time.
Right the next Test will be on the 500W 320RPM motor, watch this space! all in all its looking pretty good and I am overall impressed with the new controller, its a lot lighter than the Xlyte one as well.
See pics enclosed.
