Stock 72volt 500amp(peak) controller this controller would not drive this motor anywhere to its peak if you put on water cooling.
The biggest thing toolman2 and I did was be really careful with the hall sensor position in the motor. In the prototypes the halls are glued between the stator teeth by hand and with hot glue. (NOTE the production model does not have this design). From the factory one of our sensors was out by 25 degrees or so. We corrected this electronically using Burties Timing adjuster, and later physically by re-gluing it.
When we did stress tests and the motor heated up the glue softened and the halls moved again. We then cleared all the hot glue and then used High Temp glue and some mounting wedges to ensure all of the halls were within a few degrees of perfect. Once the halls were perfect the controllers had no issue under load or at speed.
