Testing different motor preset templates in VESC Tools Motor Wizard

The motor templates provide an estimated value for max watts it can turn into heat, open loop and sensorless eRPM, and poles. In the ebike motor, the watt loss of 150w maximum is probably right because that’s only a ~400w motor. But for a ~10 kg motor rated at 2000w, 400w loss seems reasonable My conclusion is this is why most people ignore the recommended max phase amps and use what they know the motor can handle. And max battery amps should be based on what the battery can handle. 0:00 Testing different motor wizard templates 0:30 I select E-bike Direct Drive ~6 kg motor: 150w loss which it uses to set phase current limit 0:40 Strangely, the ~2 kg motor allows for 400w loss so as will be seen it sets phase current higher for the same motor. 0:50 I set battery to 10s and 10ah 1:00 I set battery regen to -10a and battery discharge to 30a 1:10 I click 1:1 for Direct Drive motor, 355 mm tire diameter, and 40 poles so that VESC can calculate RPM and Speed 2:06 Notice it set max phase amps to 62a because thats where the motor loses 150w to heat. 2:32 runs smoothly forward but a bit glitchy in reverse. 3:08 Rated speed (no field weakening) unloaded is 39 mph 4:20 I try 6 kw ebike motor again but this time I change 150w allowed loss to 400w allowed loss. 5:50 This time it set max phase amps to 101a because thats when 400w will be turned into heat. 6:01 still silky smooth forward but glitchy in reverse 6:57 next I try 2 kg motor template with 400w loss 8:03 it set phase limit at 101a again because thats 400w loss with the motor resistance measured.
