You clearly do not understand power units (hp & watt) and efficiency calculation.
Don't be silly. The specs state both continuous mechanical hp (Torque and RPM) output = 4.14 hp and specifies electrical input power of 88 amps @ 48 volts. Efficiency = 3088 / 4224 x 100 = 73.1%. Now if I assume an efficiency of 73.1%, to get 1 mechanical hp out will cost me 746 watts / .731 = 1020 watts Electrical Input Power.
From the Specs Max Peak HP is 10 Hp. I assume that is mechanical HP and if I assume 73.1 Efficiency Input Power required is 10 x 1020 watts = 10,200 watts. My assumptions may be wrong, but my math is spot on.
At 73.1% efficiency requires 1020 watts for every HP mechanically out. So how is that wrong?
Disagree. The DC stall current using the equivalent series resistance of the motor is almost always, maybe always, higher, usually much higher, than the current limit of the controller. On any full throttle start, current limit is active. After maybe the first few pulse cycles (like 10 ms), there is no ramp function.
Funny stuff because you just agreed with me. I said Stall Current = Battery Voltage / Motor Resistance.
That is what I asked,and you cannot disagree with that, it is in all university subject matter on motors and boils down to simple Ohm's Law.
Now I agree with you DC Stall Current might, maybe, could, and/or will be higher than the Controller. Allow me to remind you the whole point of the thread was to pair a Controller/Motor. Question boils down to this.
Do you push a motor to DC Stall Current to obtain maximum start-up torque, or do you want to limit it and how much? Should not affect speed, just very low speed torque. I would think limiting Stall Current would be worth giving up some low end torque?
Induction motor LRA is not "the exact same thing as Stall Current on a DC motor." Yes, both values are the respective maximum current draw for the motor across the mains. That's where the similarity ends, IMO.
Well let others decide for themselves. I can define to textbook definitions easily looked up
LRA = Locked Rotor Current aka Start-Up current is the amount of current the Rotor will draw when the Rotor is at 0 RPM or locked. As the RPM's spools up, back EMF will press back on the voltage applied to the Rotar and current will follow Ohm's Law for AC circuits. LRA = Applied Voltage / Rotor Impedance. Sound familar?
DC Stall Current occurs at 0 RPM when full battery is applied. As RPM's spools up Back EMF presses back against the battery, lowering voltage and current of Ohm's Law. DC Stall Current = Battery Voltage / Motor Resistance.
Sounds the same to me. I am just stupid. But you are right, they are different. One use Resistance to determine Current, and the other uses Impedance which will be a little higher than it would be for DC. What do I know?
