Electronic Speed Controller

What should be the specification of ESC that I should use for a 320KV 1820W brushless DC Motor?. Is it necessary to use an 80A ESC?, Basically, How can I choose the required ESC for a motor?

• What voltage is your motor? – Mark Booth May 29 '19 at 9:56

It depends on the voltage.

Say you are running 12V:

1820W / 12V = 151A


With a 24V system:

1820W / 24 = 75A
