good morning from snowy Switzerland…
(sorry, in case I have overlooked a discussion thread on this kind of topic).
There are many different motor sizes but with the same kv rating…ranging from 6374 to the much smaller 5055 motors.
I am using a 10s4p battery pack Sony VTC6 (12000mah / 120amp) with a 40amp fuse (that can support 54amps (135%) for 30min. In order to reduce voltage sag, I have chosen such a high discharge rated cell, even though I would only use 54amps max.
For a dual setup with 83mm flywheels and 15/36 ratio, I am planning on using dual rear mounted motors, on a custom made truck…so motor size to fit on a single truck would not be a problem. I weigh 90kg and according to the skate calculator basis 190kv i should get a weighted top speed of about 35km/h which is plenty for me.
But the big question is: what kind of motor can size would be most suitable going not just on flat terrain but also should carry me up some hills? Is my assumption correct that a bigger motor 6374 would generate less heat / wasted energy compared with a much smaller 5055 motor? Where exactly are the advantages/disadvantages?
I usually cruise at an average speed of about 29km/h. Would at this average speed the motor efficiency differ between big motor and small motor?
thanks to all of you and have a good Sunday, Flo
