motor question
 

let's say i have 2 motors of the same KV.
Example would be 3500KV.

and one motor is 60mm long and 36mm in diameter
the other is 74mm long and 36mm in diameter
both are the same brand and 2 pole motors.

which one would draw more amps? does the size of the motor mean it will draw more or less with all other variables the same?

thanks-

Really? nobody knows?? :surprised::whistle:

The longer motors will always pull more amps. This is with the kv being the same.

Application would also determine amp draw.

thanks! :yes:

Same application = same amp draw.
The longer motor will run cooler than the short one and sometimes more efficient if not undergeared.
For the same temp, the longer motor can be geared up, but this will increase the amp draw.
