Here is another installment of the front wheel drive Catrike
So with the batteries installed is was on to testing... It took some time on the phone with Grin to get the Phaserunners working 100% and not flashing error codes or warnings. Here are a couple pics of the settings:
After about a week of ripping around testing, the wheels started to feel a little loose, and tightening the headsets did not cure it. Further examination revealed that both of the aluminum spindles had come loose on the headsets. So they were just floating around, and I could have lost a wheel... The aluminum spindles are press fit into the steel headset on the Catrike
, and they may also have been epoxied. So the solution was to have my friend the machinist make a pair of steel spindles, that press fit in, then weld them for further insurance.
While at the machinists I had him make up some covers for the phase wires where they exit the motor and loop back inside the spindle. The wires are very vulnerable to damage here, as this is the widest part of the trike.
The cap has spots for recessed LED lights. We changed it from the rendering to have one central spot for three surface mount LEDs.
This is the back side with a cut out for the phase wires.
So with the spindle issue fixed, on to another round of testing
The trike has exceeded my expectations for this build. It easily keeps up with local traffic at half power, and at full power it goes into warp drive, the acceleration is fantastic, and it just shoots up steep hills. The power is super controllable with the PhaseRunners working in Torque throttle mode. Is feels nice and smooth at low power, and the power comes on in a linear way across the throw of the throttle.
Top speed is over 80 Km/h, which is too fast, 50-60 is just fine. I will have to do a timed 0-60 Km/h run, it seems to get there awfully fast.
