Hi – a thank you to everyone for their help, advice and information (and patience!). I understand design fundamentals but readily concede I’m just not grasping the electrical basics.
I realise that power required is related to plane weight/ performance required. And a motor/ battery combo is then chosen to deliver that power. And the chosen propeller causes the motor to draw that power.
A 2200kv motor with a 10V battery would turn at 22,000 rpm with no load (ignoring losses) and minimum current.
When the motor is hooked up to a propeller and an ESC, am I correct in thinking the ESC controls the current/amps delivered to the motor? And that at design maximum current/amps with a well chosen motor/ battery combo, the motor will approach the theoretical maximum speed (22,000 rpm) and deliver its maximum power?
Returning to the EZ upgrade, I’ve seen articles that show a 28mm diameter inrunner (ie same diameter as stock motor) fitted into the nacelle – no mention is made of any additional cooling requirement so I have assumed it’s not an issue. With outrunners on an EZ, I’ve assumed exposure to natural air cooling in flight is sufficient.
Regards.
