Hi,
I need two HV esc' s for outrunner motors. Stator poles = 12 and Motor poles = 8.
8S batteries and 1250kV motors, so 37000 RPM Max.

The HW specs don’t say the maximum switching rate and an 8-pole motor at 37,000 rpm requires a high rate. But the problem I see is the motor Kv choice - that is excessive rpm for a large outrunner. The case will be under too much stress; I don’t know any motor maker who condones such a high rpm.
BTW, why do we never see any of Alfa’s builds running? The build pics usually look great. Enquiring minds want to know...

The HobbyKing YEP 180A HV (4 ~ 14S) Marine Brushless Speed Controller can drive a 2 pole motor at 240 000 RPM, I don' t know this esc.
I am running a Scorpion 4035/800 Kv on 10 S very reliable !!Water cooled on the mounting side and blower on top, and is all in the green even, in south Florida !!
I?m very happy for you, but that is only 23,000 rpm. The OP wants to turn 37,000 rpm, 60% more rpm than your motor. Apples and oranges.I am running a Scorpion 4035/800 Kv on 10 S very reliable....

No, 30 000 RPM (37 x 800) and the Scorpion 4035 is 10 poles. I will send an e-mail to Hobby Wing.
Ooops. Yes, so you’re only running 25% higher rpm than he is - still way too high. But you know what you know...
