Hello

I have a serious overheating problem
I use AXI5345 motor with Jeti Spin 99 Opto Brushless ESC
The voltage is static: 31.3 V
The current is static 70 A
The rotation speed is static 5400 RPM

ESC parameters
Timing 24 DEG
Frequency 8 KHz
Temperature Protection 100 Celsius
The ESC is located in the open air flow for best cooling

The problem
After 1 minute, the ESC reaches the temperature of 100 Celsius and reduces power. I need the system to work at least 10 minutes with the above parameters
Jeti spin 99 is rated to 90 A continues and up to 50V

What may be the problem and what is the solution?
