Gen 3 prius inverter and em61 motor connected to a hydraulic pump. replacing a 50hp 2700 rpm diesel engine.
im only getting 245 apms on the phase wires and rpm drops to 1300.

42s lips battery
At 1300rpm motor voltage is 67 and 246 ac rms amps max so 28.5kw input to motor
At 2100 rpm motor is 98v ac
Amp clamp says 40 amps, inverter gui says 17 amps
84s
Motor side
Max ac amps 245, min volts 67, max 144vac
Battery side
46amps max
Im learning that phase amps as a rating are meaningless and really need a the 1 hour max battery amps. if i can not maintain 500 battery amps then i think i will just a use a vesc instead.
