If I have a Brushless 3-phase motor that spins at 3000rpm when given 6.0A @ 20v (no load) will it produce 6.0A and 20v (or anywhere close) when used as a generator and spun at 3000rpm??
And i suppose this comes into it too... Will a 3-phase bridge rectifier make DC more or less as efficiently as an ESC turns DC into a 3-phase signal??
....UPDATE: So this is the motor I am thinking of using now:
MOTOR: 5065 KV: 270 MAX POWER: 2200W WIRE WINDS: 9 MAX AMP: 60A ESC: 80/120A MAX VOLT: 8S RESISTANCE (Ohm): .42 NO LOAD CURRENT: 1,5 SIZE: 50 x 65 ( without shaft ) WEIGHT (g): 0,380 SHAFT: 8mm with 3mm keyway
I will use a pulley to spin it at 18000rpm hopefully resulting in about 60v..
Does anyone know what current I can expect?
And being a 2200w motor (more than the engine that is powering it (700w)) ,when i connect it to the mppt charge controller will the engine struggle to turn as the load creates effort? Or can I expect that it will be creating far fewer amps than it draws when used as a motor at this voltage and under load?...
